For roofing contractors, estimators, and owners of roofing businesses

A licence, two policies, and a bond are four promises to four different people.

Practitioner reference · residential and commercial · United States

They get conflated constantly — in marketing copy, in bid documents, and in the sentence “licensed, bonded and insured,” which describes four unrelated instruments as though it were one credential.

30-second answer

What do a contractor licence, general liability, workers' compensation, and a surety bond each actually do?

A licence is a government's permission to contract for the work, and its rules are state and sometimes city law. General liability pays third parties for injury and damage your operations cause; your own defective work is treated separately. Workers' compensation pays your injured employees and buys you exclusive remedy. A bond pays your customer or the state — and the surety collects it back from you.

Stop — immediate hazard

If someone on your crew is hurt, the coverage question waits. The medical care and the reporting clock do not.

Those windows run from the death or the hospitalisation, not from the day you work out who the insurer is or whether the injured person was on your payroll or a sub’s. Whether a state-plan state adds its own requirements on top is a separate question to put to your state agency, and 29 CFR 1904.39 is the federal text.

Nothing further down this page is more urgent than either of those two things. Fall protection is its own subject — OSHA states that “falls are the leading cause of death in construction,” citing BLS data for 2024 showing 389 fatal falls to a lower level out of 1,034 construction fatalities, a construction-wide figure rather than a roofing-specific one. See fall protection on roofing work.

Get the person medical attention first. Then note the time: where OSHA’s reporting rule applies to your operation, a work-related fatality must be reported within eight hours, and an in-patient hospitalisation, an amputation, or the loss of an eye within twenty-four hours, by phone or in person to the nearest OSHA Area Office, by phone to 1-800-321-OSHA, or through the reporting application on OSHA’s website.

Learning paths and saved lessons

At a glance

Four instruments, in one line eachSection link

Every jurisdiction statement on this page names the agency that issued it and the date the source was read. There is no national contractor licence and no national roofing licence; the six jurisdictions used here — five states and one city — were chosen because they run genuinely different systems, not because they represent the country.

A licence or registration: A government's permission to contract for the workSome states license roofing specifically, some license contracting above a dollar threshold, some register home-improvement work only, and some do neither at state level while cities do. Verify with the issuing authority, not with an aggregator.
General liability: Pays third parties for bodily injury and property damage arising from your operationsHow it treats your own defective work is the part contractors misread. South Carolina legislated on the question in 2011 and still wrote the carve-out into the statute: “exclusive of the faulty workmanship itself.”
Workers' compensation: Pays your injured employee without proof of fault, and bars most suits against youWhether you must carry it — and whether you may exempt yourself — is state law. California forbids a C-39 roofing licensee from claiming the no-employee exemption at all. Texas lets most private employers decline coverage entirely.
A surety bond: A three-party guarantee: you, the surety, and a beneficiary the statute or contract namesThe surety pays the beneficiary and then collects from you under the indemnity agreement you signed. Treat the bond line on your balance sheet as contingent debt, not as cover.
A certificate of insurance: A dated summary of policies that existed on the day the agency issued itNew York's regulator: a certificate “cannot confer new or additional rights beyond those set forth in the referenced insurance policy.” Texas's regulator says a certificate “may not use terms that would alter, amend, or extend coverage.”
Where the rules come from: State statute, state administrative rule, city ordinance, and your own contractsFour independent layers. A commercial general contractor's insurance requirements routinely exceed anything your state asks of you, and they are enforceable against you because you signed them.

Tradeoffs

This page's position — carry more than the minimum, classify honestly, and treat a bond as debt — and where that position is wrongSection link

The general advice here is to buy above the statutory floor, to put people on payroll when they behave like employees, and to read a bond as a credit facility rather than a badge. Each of those is wrong under conditions worth naming.

Best when

You employ a crew, work at height every day, and operate in a state whose minimum limits were set decades ago and never indexed.
You bid commercial or institutional work, where the general contractor's insurance schedule and bonding requirement will exceed the state's floor anyway and the cheap policy simply loses you the job.
Your crews are directed by your foreman, use your equipment, and work your schedule — the facts the IRS calls behavioural and financial control point one way, and the paperwork should not point the other way.
You want bonding capacity later. Sureties underwrite working capital, net worth and completed-job history; the file you build now is what a bond line is priced off in three years.
You are the named insured on a policy that has never had a claim, and you are tempted to read that as evidence the policy is broad. It is evidence of nothing except that you have not tested it.

Think twice if

You genuinely are a one-person operation in a state that offers an exemption, and buying coverage you are not required to carry is a real cost against a real cash-flow problem. That is a business decision, not a compliance one — but see the divergence section: the exemption may move an exposure onto the property owner rather than remove it.
You are being sold limits by someone paid on the premium. Higher is not automatically better; the right question is what your contracts require and what your realistic worst case is, not what the largest number on the quote sheet is.
A bond is being demanded on private residential work by a customer who has read that “bonded” means their money is protected. It usually does not mean that, and buying one to close a sale is buying a misunderstanding.
You are in a state that publishes a low licensing bar. A bond and a licence that cost a few hundred dollars and require no examination tell your customer very little, and pricing yourself as though they told them a lot is a losing argument.
You are considering a captive, a PEO, or a group self-insurance arrangement. Those change the analysis on this page substantially and are outside what a published guide can evaluate for your business.

What changes the answer

Your state, and often your city. The four instruments exist everywhere; which of them the government requires, and at what level, does not.
Whether you have employees, and whether your state counts owners, officers, family members, and subcontractors' workers toward that number. The counting rules differ from the coverage rules.
Your experience factor. It is the multiplier on your comp cost and it moves with your own claims history, so today's safety programme prices next year's payroll.
The contracts you sign. Additional-insured wording, waivers of subrogation, indemnity clauses, and required limits are negotiated obligations that sit on top of anything the state requires.
Whether the work is insurance-restoration. Several states regulate what a roofer may do inside a claim, and those rules bind you regardless of what your licence permits.
Whether you are ever going to sell the business. Classification exposure and uninsured periods surface in diligence, and they are priced.

The mechanism

Four instruments, four beneficiaries, one return arrowSection link

The reason these get conflated is that you buy all four from adjacent-looking people and file all four in the same folder. They are not the same kind of thing, and only one of them sends the money back.

What each instrument costs you, and who receives what it pays. The dashed return arrow on row four is the distinction that matters most: a surety expects to be made whole, an insurer does not.Original diagram, Understanding Roofing

A licence is permission. A government has decided that this work should be done by people it can identify and discipline, and it has attached conditions to that permission. Some of those conditions are competence tests. Many are not — several of the credentials below require documented experience and no examination at all.

General liability and workers’ compensation are insurance: you pay a premium, the insurer takes the risk, and the insurer does not come back to you for what it paid. They cover different people. General liability faces outward, toward third parties. Workers’ compensation faces inward, toward your own employees, and in return for that no-fault payment most states bar the employee from suing you in tort — the exclusive-remedy bargain, which is the part that protects you rather than them.

A surety bond is not insurance and behaves nothing like it. It is a three-party guarantee. The surety promises a beneficiary — a customer, a state agency, an obligee named in a construction contract — that you will perform or pay. If the surety pays, it looks to you for reimbursement under the general indemnity agreement you signed, and in a small contracting business that agreement is usually personal and usually includes a spouse. The premium is the fee for lending you the guarantee, not the price of transferring the risk.

A certificate of insurance is none of the above. It is a piece of paper that describes two of them as they stood on the day it was printed.

“Ultimately funds it” is the question that separates insurance from surety. On rows two and three the insurer bears the loss. On row four you do, and the premium only buys the guarantee.

The jurisdiction problem

There is no such thing as “a roofing licence”Section link

There are at least four different regimes operating simultaneously across the United States, and which one you are under is decided by geography rather than by trade.

The four regimes, in the order a contractor usually encounters them:

A roofing-specific state licence. The state has decided roofing is its own regulated trade, with its own classification, its own examination or experience requirement, and its own insurance and bond conditions.
A general contracting licence gated on money. The state does not care what trade you are in; it cares what the job costs. Below the threshold you need nothing from the state. Above it you need a licence, and the licence is not roofing-specific.
Home-improvement registration or licensure. The state regulates the consumer transaction rather than the trade. Insurance and a fund or bond are usually conditions; a test of roofing competence usually is not.
Nothing at state level. The state licenses other trades and not this one — and cities in that state may license or register you anyway, with their own experience requirements and their own permit consequences.

Six jurisdictions, below — five states and one city — running four of those systems. Each entry names the issuing authority and the date its own page or statute was read. None of it is legal advice, and none of it substitutes for asking the authority itself: adopted rules change, thresholds get amended, and a live URL proves nothing about whether the page behind it is current.

Six jurisdictions — five states and one city — across four regimes. Every cell is drawn from the issuing authority's own statute, rule, or page, read on 27 August 2026. This is a demonstration of range, not a survey — forty-five states and every other city are missing.

Workers' compensation, unconditionally: C-39 licensees “are required to carry workers' compensation insurance or a valid Certification of Self-Insurance, whether or not they have employees” (B&P section 7125). A C-39 may not file the no-employee exemption other classifications may file. Letting coverage lapse suspends the licence, and work performed while suspended “is considered to be unlicensed.”	A $25,000 contractor licence bond, at that amount since 1 January 2023 under SB 607, “filed for the benefit of consumers who may be damaged as a result of defective construction or other license law violations, and for the benefit of employees who have not been paid wages that are due to them.”
Illinois — IDFPR	Roofing-specific state licence	Limited or Unlimited roofing licence under the Illinois Roofing Industry Licensing Act, 225 ILCS 335. The Act makes it “unlawful for any person to engage in the business of providing professional roofing services … without having been duly licensed.” Limited covers “roofing residential properties consisting of 8 units or less”; Unlimited covers residential, commercial and industrial.	Liability cover of $250,000 per occurrence for property damage and $500,000 per occurrence for personal injury or bodily harm, with 30 days' notice of cancellation to the Division.

A surety bond of $10,000 for a limited licence and $25,000 for an unlimited one, from an insurer authorised to write surety in Illinois, with 60 days' notice of cancellation (68 Ill. Adm. Code 1460).
North Carolina — statute	General contracting, gated on the cost of the job	The statutory definition turns on money, not trade: a general contractor is anyone who undertakes work “where the cost of the undertaking is forty thousand dollars ($40,000) or more” (G.S. 87-1).

It excludes consequential damage, legal fees and court costs, and it “will not reimburse a claimant for money paid to an unlicensed home improvement contractor.”

There is a third for green roof systems only.
Insurance required to hold it: Not stated on the certificate page read here.
Bond or fund: Not stated on the certificate page read here.

The point of the table is the variation between rows, not any single row. Confirm your own jurisdiction with the authority that issues the credential — a state board, a state agency, or a city building department — and not with a directory that aggregates them.

The two things the table is actually for

The first is the entry-cost asymmetry. Denver’s two roof-covering certificates each require two years of experience and at least twenty-four documented projects from different months — and no test. Illinois requires an examination, a qualifying party in responsible control, named insurance limits, and a bond. California requires a bond and workers’ compensation that a sole operator cannot exempt out of. Texas requires nothing of you as a roofer at state level. If you expand across a state line, the cost and the lead time of becoming legal there can differ by an order of magnitude, and the difference is not correlated with how hard the roofs are.

The second is that the credential says less about competence than either you or your customer would like. Two years and twenty-four projects is a real bar and it is not a skills test. A bond is priced off your credit. A licence number proves that a government has a file on you, which is genuinely valuable — it is what makes a complaint go somewhere — but it is not evidence that the last roof was flashed correctly. That work is judged by the roof, which is what flashing details and workmanship and the defect catalogue are for.

What to actually do about it

Identify the level of government that regulates you, and confirm it is only one. State plus city is common; assuming the state licence covers the city is how permits get refused on a Monday morning.
Read the reciprocity rules before you assume there are any. Most roofing credentials do not travel.
Diary the renewal, the continuing-education requirement if there is one, and — separately — the expiry date of every policy the credential is conditioned on. In California a comp lapse suspends the licence, which retroactively makes work unlicensed. The insurance calendar and the licence calendar are the same calendar.
Check whether your state counts a qualifying individual, a responsible managing employee, or a qualifying party separately from the business entity. If that person leaves, the licence can go with them.

The exclusion nobody reads

General liability and your own defective workSection link

The single most consistent misunderstanding in this subject is the belief that a general liability policy is a backstop for bad workmanship. It is very largely the opposite.

A commercial general liability policy responds to bodily injury and property damage caused by an occurrence. The architecture that surprises contractors is that the policy is built to pay for what your work does to other things and other people — and is not built to pay for replacing the work itself.

Whether it pays at all, and for what, is a question about your specific policy, its endorsements, and the law of the jurisdiction whose law governs it. This page will not tell you the answer, because there is no national answer and publishing one would be a false comfort.

What is not arguable

What is beyond argument is that the question has been contested hard enough that legislatures intervened. South Carolina’s statute, effective 17 May 2011, requires a commercial general liability policy offered for sale in the state to define “occurrence” to include an accident and to include:

“property damage or bodily injury resulting from faulty workmanship, exclusive of the faulty workmanship itself.”

Read the last four words. That is a legislature requiring insurers selling in its state to treat faulty-workmanship damage as an occurrence — a requirement that plainly operates in contractors’ favour — and writing the faulty workmanship itself back out of it in the same sentence. The same statute adds that it “is not intended to restrict or limit the nature or types of exclusions from coverage that an insurer … may include.”

The practical translation, stated as an expectation rather than a coverage determination: plan on funding the removal and replacement of your own defective work yourself. The money to tear off and redo a slope you nailed high is a callback cost, not usually a claim. What may be a different question is the damage that defective work caused to something that was not your work — the ceiling, the flooring, the contents, the wall assembly below a missing kickout. Whether your policy reaches that is for your policy and your jurisdiction to say.

Consequences for how you run the business

Price callbacks as an operating cost, not an insured event. A callback reserve is a real line in a real budget. If your margin model assumes the policy absorbs rework, the model is wrong in a direction that compounds.
Your workmanship warranty is unfunded unless you fund it. A ten-year workmanship warranty is a promise backed by your own future cash flow and by your continued existence as a business. That is worth saying out loud to a customer rather than implying that an insurer stands behind it.
Completed-operations matters more to a roofer than to most trades. Roof leaks announce themselves years after the crew left. Confirm with your agent how long your completed-operations exposure is covered and what happens to it if you change carriers, and get the answer in writing.
Read the additional-insured wording you are agreeing to. On commercial work you will be asked for additional-insured status, primary and non-contributory wording, and a waiver of subrogation. Those are contractual obligations you accept by signing, and your policy may or may not deliver them. The certificate that says you have them is not the endorsement that gives you them.
Subcontractor requirements are your exposure, not theirs. If you sublet and your sub is uninsured, the claim tends to find you. The controls are a written subcontract, a certificate obtained from the sub’s agency, and a real check of the policy dates against the dates the sub was on your roof.

Where the money and the risk are

Workers' compensation, classification, and the exposure that bitesSection link

Comp is the largest insurance line most roofing companies carry, and the way it is priced creates a permanent temptation to describe crews as something they are not.

The arithmetic above shows why. Comp is rated on payroll or on hours in a roofing classification, so anything that moves people off payroll — or into a cheaper classification — moves the number. Paying a crew as 1099 subcontractors makes the comp line, the payroll-tax line, and the unemployment-insurance line smaller immediately. That is precisely why it is the most examined arrangement in the trade.

Three separate authorities, three separate tests

The mistake is thinking classification is one decision. It is not. Federal tax law, federal wage-and-hour law, and each state’s workers’ compensation and unemployment systems each apply their own test, and a worker can come out differently under different ones.

On the federal tax side the IRS applies common-law rules grouped in three categories: behavioural — “does the company control or have the right to control what the worker does and how the worker does his or her job?”; financial — who controls how the worker is paid, whether expenses are reimbursed, and who supplies tools and supplies; and type of relationship — written contracts, employee-type benefits, permanence, and whether the work is a key aspect of the business. The IRS is explicit that there is “no ‘magic’ or set number of factors” and that “no one factor stands alone.” A business or worker who genuinely cannot tell can file Form SS-8 and ask for a determination; the IRS says that takes at least six months.

Apply those three categories honestly to a roofing crew that shows up in your truck, works the schedule your foreman sets, uses your compressor and your nailers, and roofs only for you. Most people who do that exercise carefully already know the answer.

The federal wage-and-hour test is a different test with a different standard, and it has been the subject of successive rulemakings and litigation. This page does not state its current content, because the Department of Labor’s own pages could not be read from here — see the limitations. Ask an employment lawyer in your state what standard applies to you today rather than relying on any published summary, including this one.

The exposures that make this urgent rather than merely expensive

An injured worker with no coverage anywhere. The person still needs care, and the cost lands somewhere. Where it lands depends on your state’s rules about uninsured employers, about general contractors’ liability for uninsured subs, and about who counts as an employee for comp purposes — which is a different question again from who counts for tax.
Premium audit. Comp premium is audited against actual payroll and, in many arrangements, against payments to uninsured subcontractors. A sub who cannot produce a current certificate can be charged to your payroll at audit. Collect certificates before the sub starts, not at audit time.
Licence conditions. Where the licence is conditioned on coverage, a lapse is not only an insurance problem. California suspends the licence, and work done while suspended is unlicensed work.
The exclusive-remedy bargain only holds if you kept your side. The reason comp bars most employee suits is that the employee gets paid without proving fault. An employer who was supposed to carry coverage and did not is, in many states, outside that bargain. Texas makes the trade visible because it is optional there: a non-subscriber keeps the premium and loses the protection, and its regulator says so plainly.

Credit, not cover

What a bond is, what it costs, and why it is on the wrong side of your balance sheetSection link

“Bonded” is the word in the phrase that means the least to a customer and the most to your banker.

A surety bond involves three parties. The Texas Department of Insurance describes them as “the Surety (insurance company) that guarantees the faithful performance of the Principal (sometimes referred to as the Obligor) to the Obligee the owner or entity that is expecting an obligation to be completed.” You are the principal. The surety is not taking your risk; it is lending you its credit and expecting to be made whole if it has to pay. That expectation is written down in an indemnity agreement, which the same regulator describes as requiring “that the surety (insurance company) is completely indemnified against any liability, loss, cost, attorney’s fees and expenses whatsoever that the surety shall sustain by having been surety on this bond.”

Who signs that agreement is a question about your agreement rather than a rule this page can state. In a small contracting business it commonly reaches the owners personally, and a surety may ask a spouse to sign as well. Read the signature page of yours before you assume otherwise; that is the document that says who the surety can collect from.

California’s licence bond is a clean example of what the instrument is for. It is $25,000, at that level since 1 January 2023, and the Board states it is “filed for the benefit of consumers who may be damaged as a result of defective construction or other license law violations, and for the benefit of employees who have not been paid wages that are due to them.” Note who is in that sentence and who is not.

The kinds you will meet, in the order you meet them

Licence or permit bond. Required by a statute or a city as a condition of the credential. Sized by the government, usually small, and usually the only bond a residential contractor ever buys. Its face amount is a limit on the bond, not an allowance per customer — California’s Board says of its own bond that “the bond amount is not per job” and that once it is depleted a new one must be purchased for the licence to remain in effect. Check how the bond you are required to carry is written.
Bid bond. Guarantees that if you win, you will enter the contract and provide the performance bond. Common on public work.
Performance bond. Guarantees the owner that the contract gets completed. Sized on the contract value.
Payment bond. Guarantees that your suppliers and subs get paid — which is why it exists on public projects, where a lien against public property is generally unavailable.

Bonding capacity is an asset you build, not a product you buy

A surety underwrites your working capital, your net worth, your organisation, and your record of finishing jobs of a comparable size. It will want reviewed or audited financial statements, a work-in-progress schedule, and a continuity plan. None of that can be assembled the week a bid is due.

The practical consequence is that the bookkeeping discipline you build for your own job costing is the same file a surety reads. If you intend to bid commercial or institutional work later, the accounting habits you set now determine the size of the job you are allowed to bid then — which is a reason to take overhead recovery and job-level costing seriously well before the first bond is needed.

A fund is not a bond, and it is worth knowing the difference

Some states replace the individual bond with a pooled fund. Maryland runs a Guaranty Fund “supported by licensed contractors, who pay a Guaranty Fund assessment” at licensing and at each renewal, which reimburses a homeowner’s “actual loss” from unworkmanlike, inadequate, incomplete or abandoned work — up to $30,000 per claimant or the amount the homeowner paid, whichever is less, and $250,000 in aggregate against a single contractor.

Two features of that arrangement are worth a practitioner’s attention. The fund pays a customer of a licensed contractor — it “will not reimburse a claimant for money paid to an unlicensed home improvement contractor,” which is a direct financial argument for the licence being visible on the contract. And it excludes consequential damage, legal fees and court costs, so it is a floor under a customer’s loss rather than a resolution of a dispute.

Paperwork that gets misread in both directions

Certificates of insurance, and why the customer calling your agent is reasonableSection link

A certificate is evidence about a moment. It is not coverage, it is not a contract, and treating a request for one as an insult is a mistake.

Two state regulators put the legal character of a certificate about as plainly as it can be put. New York’s Department of Financial Services, in a 2011 general-counsel opinion, described a certificate as “a document that summarizes the terms, conditions, and duration of an insurance contract, but it is not the contract itself,” and said it “cannot confer new or additional rights beyond those set forth in the referenced insurance policy.” The Texas Department of Insurance says a certificate “may not use terms that would alter, amend, or extend coverage that is provided in the insurance policy,” and that the certificate-holder box may not be used “to imply or confer any new or additional rights beyond what the policy or any executed endorsement of insurance provides.”

Three things follow that are useful on both sides of a driveway.

A certificate is a snapshot with an expiry problem. Your general liability and your comp almost never renew on the same date. A certificate issued in March showing both policies can be accurate on the day it is printed and stale before the crew arrives in September. When you send one, send one that spans the work.
Being named certificate holder confers nothing. If a general contractor needs additional-insured status, that is an endorsement to your policy, not a line in a box. Sending a certificate with “additional insured” typed into it, without the endorsement behind it, is at best an accident waiting for a claim and at worst something your regulator treats as a misrepresentation.
Forwarding a PDF is not the same as having your agency issue one. A document that arrives from your own inbox has been through your hands. A document that arrives from the agency named on it has not.

The overlap with the buyer side of this site, stated honestly

This site’s guide to choosing a roofing contractor tells homeowners to get the certificate from the agency rather than from the contractor, and to check the policy dates against their scheduled work. That guide and this page are written for people on opposite sides of the same transaction, and it would be dishonest to soften the advice here because the reader changed.

So: the advice stands, and it is not an accusation. Agencies issue certificates constantly; it is routine, it is free, and it takes an email. Asking your agency to send one directly costs you nothing and removes a category of doubt that you cannot otherwise remove, because any contractor could forward any PDF. Contractors who make it easy find it becomes a small proof point rather than an awkward moment — and contractors who resist it hand a well-prepared buyer a reason to hesitate, for no gain.

Being straight with both sides

Where your interests and your customer's genuinely divergeSection link

This is an independent consumer-education site with a trade section, not a contractor's business partner. Pretending the interests always align would make everything else here less useful.

There are places where the cheaper choice for you is the riskier position for the person paying you. Naming them is more useful than pretending otherwise, and none of them makes you a bad operator — they are structural.

Coverage levels

Carrying a state-minimum limit, or taking a lawful comp exemption as a sole operator, lowers your cost and moves an exposure rather than eliminating it. If something goes badly wrong, the money has to come from somewhere, and the homeowner is in the chain. Whether it actually reaches them depends on their own policy and on your state’s law — which is exactly why a buyer is told to ask, and why the honest answer when they do is the real one.

Classification

A crew paid as subcontractors costs you less per hour. If those people are functionally your employees, the saving is a transfer of risk to them, to your customer, and eventually to you when an auditor or a claim arrives.

Scope language in a proposal

A vague scope is easier to sell and easier to defend on price against a competitor. It is also the thing that makes three proposals incomparable, and it is what the buyer-side pages exist to defeat. The defensible answer is not vagueness; it is a scope specific enough that a cheaper bid has to explain what it left out — the argument the hiring and quotes path is built around from the other direction.

Practices that are simply off the table

Some of this is not a question of interests at all. Texas is an instructive example because its regulator writes it down: the Texas Department of Insurance states that “Texas doesn’t allow a roofer or contractor to act as a public insurance adjuster on insurance claims if they’re also doing the work,” and that “it’s also illegal in Texas for a contractor to offer to waive, rebate, or absorb a property policyholder’s deductible,” with a required notice in contracts of $1,000 or more. Those are Texas rules, read on 27 August 2026, and they are not national — but the pattern is: several states regulate what a roofer may do inside an insurance claim, and the practices they target are the ones that help close a sale.

The general position of this site is unchanged in the trade section: nothing here is intended to help anyone present a roof, a credential, or a price as something it is not. Good practitioners do not need that, and it is the fastest route to the enforcement file that a licence exists to create.

What this page is not

This page needs jurisdiction-appropriate legal review, and has not had itSection link

Licensing, insurance, bonding, and worker classification are all areas where a published summary can be accurate in general and wrong for you in particular.

Everything above describes instruments and cites the authorities that govern them in named jurisdictions on a named date. None of it is a determination about your business. In particular, this page does not and cannot tell you:

whether you need a licence where you work, or which one;
whether your policy covers any particular loss;
whether any contract term you have signed is enforceable;
whether any worker you engage is an employee or an independent contractor under any of the tests that apply to you; or
whether you are in compliance with any obligation, to any agency, at any time.

Those are questions for the issuing authority, your carrier or broker, and a lawyer admitted where you work. The site’s editorial and corrections policy explains how a claim on this page is challenged and changed; the source stamp below records exactly which document supports which sentence, and which ones could not be read at all.

The practical residue

A compliance calendar, not a compliance folderSection link

Most of the failures in this subject are date failures rather than knowledge failures. The instruments were bought and then not watched.

One calendar, four kinds of date. Licence renewal, continuing education if required, each policy’s expiry, and each bond’s renewal. Where a licence is conditioned on a policy, a lapse in one silently invalidates the other.
Ask your carrier for your rate and your factor in writing, annually. Both are inputs to your unit price. If you cannot state them, you cannot load them into a bid.
Check your classification assignment. Payroll in the wrong class code is expensive in one direction and a premium-audit problem in the other.
Collect subcontractor certificates before mobilisation, from the sub’s agency. Diary the earlier of the two policy expiry dates against your schedule.
Keep the qualifying-individual question answered. If your credential depends on a named person, know what happens to it the week that person resigns.
Read the insurance schedule in any commercial contract before you price it. Additional insured, primary and non-contributory, waiver of subrogation, and required limits are cost items, and they are sometimes not available on your current policy at any price.
Know which of your certificates is the current one. If you cannot produce a certificate spanning today’s work in under five minutes, neither can a general contractor’s compliance system, and that is how invoices get held.

Scaling up

What changes when the work becomes commercialSection link

On a residential reroof the state sets the floor. On commercial work the contract sets the floor, and it is usually much higher.

The practical shift is that a general contractor or an owner’s risk manager, not a state agency, becomes the party dictating your insurance. Expect a schedule that specifies limits well above statutory minimums, additional-insured status on an ongoing and completed operations basis, primary and non-contributory wording, a waiver of subrogation, and sometimes an umbrella. Expect payment and performance bonds on anything public and on much private work above a threshold the owner picks.

Expect also that compliance is automated. Many general contractors run certificate-tracking systems that hold your payment application when a policy date passes, without a human deciding to do it. The administrative cost of that is real and belongs in your overhead, not in your evenings.

The prequalification package itself — financials, safety record, EMR, bonding letter, references of matching scope — is a separate subject from this page, and roof-specific commercial context sits under commercial roofing. What belongs here is the sequencing point: bonding capacity and an insurance programme that satisfies a commercial schedule are both built from financial records over years. Deciding to bid commercial work is a decision you implement two or three years before you make it.

The arithmetic

What workers' compensation actually costs a roofer, worked throughSection link

Washington publishes its state-fund rates by risk classification, which lets this arithmetic run on a real, checkable, government-issued number rather than an invented one. Washington's figures do not transfer to your state. The shape of the calculation does.

Roof work, Washington, 2026: $5.7930 per worker hourRisk classification 0507, Roof Work — Construction and Repair. Composite base rate for state-fund firms, at an experience factor of 1.0000. The 2025 rate was $5.8440, a change of −1%.
Same rate, per full-time worker-year: $11,122.565.7930 × 1,920. L&I's own rate notice defines a full-time employee as 1,920 hours worked.
All building construction and trades, same table: $2.5106 per worker hourRoof work is 5.7930 ÷ 2.5106 ≈ 2.3 times the composite for the entire building-trades group in the same document. That ratio is the priced consequence of working at height.
The cost of an experience factor of 1.40: $2.84 more per worker hourAgainst a factor of 0.91: (1.40 − 0.91) × 5.7930 = 2.83857. Over one 1,920-hour worker-year that is $5,450. On a 30-square roof at two worker-hours per square, $170.

Derivation: hourly rate × experience factor × worker-hours per square. 0.91 is the average factor L&I assumes when it computes standard premiums; 1.40 is chosen to show the slope, not because it is typical. Rounded to the cent at the last step only. This is Washington's state fund and Washington's rating basis — worker hours, not payroll dollars — and none of it is a quote for any employer, including one in Washington.

Units: U.S. dollars per worker hour worked, and per roofing square (100 sq ft) after multiplication by a worker-hours-per-square input.
Scope included: The state fund's published composite base rate for one risk classification, and arithmetic performed on it.
Not included: Every other cost of employing a roofer: wages, payroll taxes, general liability, vehicle and equipment cover, unemployment insurance, and any employee-paid share. It also excludes self-insured employers, retrospective-rating participants, and any employer outside Washington's state fund.
Geography: Washington State only. Washington rates workers' compensation on hours worked in a risk classification. Most states do not use that basis, and the number does not travel.
Data as of: 2026 rate year. L&I's published 2026 rate notice, read 27 August 2026.
Confidence: High for the published rate itself, which is quoted from the agency's own table rather than from a summary of it. The per-square figures are arithmetic on that rate and on a worker-hours-per-square figure the reader supplies; they are exact given those inputs and meaningless without them.
Method: How this site builds and states any figure

Why this is the one number worth publishing

In much of the country workers’ compensation is bought from private carriers at rates that are not published as a single public table, so a national figure for roofing comp would have to be invented. Washington publishes its state-fund rates by risk classification every year, which means the arithmetic above runs on a real, checkable, government-issued number. That is the whole reason Washington is here — it is not the only state fund that publishes rates, and it is not a proxy for your state. If your own state runs a fund, look for the equivalent table; if it does not, your carrier has the rate and the factor and can put both in writing.

What does transfer is the structure. Somewhere in your own arrangement there is a rate, a classification, and a factor that scales the rate by your own claims history. Those three things multiply. Once you can see the multiplication, two things become obvious that are invisible when comp is a single annual invoice.

The first: comp is a variable cost, and it belongs in the unit price

At two worker-hours per square — the number you should be taking from your own job-costing rather than from this page — the Washington rate puts $11.59 of comp into every square you install before you have bought a single bundle. On a 30-square roof that is $348. A bid that recovers overhead as a flat percentage and never separates this out will systematically underprice steep, cut-up, slow work and overprice fast, simple work, because comp follows hours and hours follow difficulty. That is the same failure the pricing and margin page attacks from the overhead-recovery side, and the same reason takeoff that stops at area is not takeoff.

The second: your safety record is a line item with a two-year echo

The gap between a 0.91 factor and a 1.40 factor is $2.84 per worker hour on the Washington rate — $5,450 a year for every full-time roofer, and about $170 on a single 30-square roof at two hours per square. A five-person crew at that spread is roughly $27,000 a year of pure factor. Nothing about the work changed; only the claims history did.

This is the honest commercial argument for a fall-protection programme, and it is worth stating in the same breath as the moral one rather than instead of it. A claim you avoid this year prices your payroll for years afterward, and no bid you win in the meantime recovers it.

For how this site states any figure — units, scope, geography, as-of date, and confidence — see the cost methodology.

This is a published rate for one classification in one state, not a premium and not a quote. Your premium depends on how your payroll is classified, on your own experience factor, on the carrier or fund you are with, and on arrangements — deductible programmes, retro, group self-insurance — that this page cannot evaluate. Ask your carrier for your own rate and factor, in writing.

Considerations

What changes this on a real businessSection link

Four axes decide how much of this page applies to you, and none of them is the roof.

Jurisdiction, and how many of them you are in: Every credential above is issued by a named authority under a named statute or ordinance. The instruments are universal; the requirements are not. Crossing a state line, and often a city line, restarts the question — and a state licence does not normally satisfy a municipal registration requirement or the reverse.There is no national contractor licence and no national roofing licence, so there is no single answer to check. Confirm requirements with the authority that issues the credential, on its own site, and record the date you did it — a requirement can change without the page you read last year changing.
Whether you have employees, and who counts as one: Coverage requirements, exemptions, and the number of workers that triggers them are state law, and the counting rules are not the same as the coverage rules. Owners, corporate officers, family members, and an uninsured subcontractor’s crew are each treated differently in different states, and a person can be outside the count for one purpose and inside it for another.A determination that a specific worker is an employee or an independent contractor is made by an agency or a court on your facts. Nothing on this page is that determination.
Your own claims history: The experience factor is the one input in the comp arithmetic you control directly, and it moves slowly in both directions. It is also the number a general contractor asks for during prequalification, which means a bad year prices your work and narrows the work you are allowed to bid at the same time.
The contracts you have already signed: Additional-insured obligations, indemnity clauses, required limits, waivers of subrogation, and bonding requirements sit on top of anything a state requires and are enforceable against you because you agreed to them. Read the insurance schedule before you price the job, not after you win it.Whether any particular contract term is enforceable is a question of the law where the work is performed, and one this page cannot answer.
Height, and what it does to the price of the risk: Roof work in Washington’s published 2026 table is rated at about 2.3 times the composite rate for the whole building construction and trades group. That is one state’s rating of one classification rather than a national measurement of the hazard, but the direction of it is not surprising, and it is a straightforwardly financial argument for the fall-protection programme you should be running anyway.

The promises you make

Warranties, callbacks, and who is actually standing behind themSection link

Three different documents get called a warranty on a roofing job, and only one of them is yours to fund.

The manufacturer's material warranty: A contract between the owner and the manufacturer, on the manufacturer’s terms, covering the product. It is not your obligation, and it is not evidence about your work — but the installation instructions it depends on are, which is why an installation defect can end the conversation before the material is examined.
Your workmanship warranty: A promise you fund from your own future cash flow. There is no policy behind it and no surety standing under it. Its real cost is a reserve and a callback process, and its real value to a customer depends entirely on whether your business still exists when it is called on.
A manufacturer system or NDL warranty: Available only through a credentialled installer and usually conditioned on specified components, an inspection, and registration within a window. Read it as an obligation you take on — a documentation and sequencing commitment — rather than as coverage you acquire. The consumer-side detail is on roofing warranties.
What your liability policy does with a warranty claim: Not what most contractors expect. A general liability policy is not a workmanship warranty, and the standard architecture treats damage to your own completed work differently from damage to everything else. Plan the rework as an operating cost. Ask your broker, in writing, what your policy does with resulting damage to other property.

Repairability

The economics of a callback are the reason this section sits on a licensing page. Rework is priced at standalone mobilisation — a truck, a crew, a day, no adjacent work to absorb the overhead — and it lands on a job whose margin was booked and spent. A callback rate of a few percent of jobs is enough to erase the difference between a profitable year and a flat one.

Which makes the defect catalogue an accounting document as much as a technical one: the specific details that generate callbacks are knowable in advance and mostly the same ones every time. See common roofing defects and flashing details and workmanship, and the planning-range framing on roof service life for why a warranty term is not a lifespan.

A warranty is a contract between a reader and whoever wrote it. What it covers, what voids it, whether it transfers, and how it is enforced are set by that document and by the law where the reader lives. Read the actual warranty for the product and the installer in front of you — not a summary of one, including this one.

Ask before you renew

Questions to put to your agent, your broker, and your suretySection link

These are the questions whose answers you will need under pressure, when there is no time to find out. Ask them at renewal, when there is.

What is my classification code, my rate, and my experience factor this year — and what were they last year?
These are the three inputs to your largest insurance line and to your unit price. A broker who cannot produce them quickly is not managing the account. A factor that moved without a claim you remember is worth a conversation with the rating bureau or fund.
How does my general liability policy treat damage to my own completed work, as distinct from damage that work causes to other property?
This is the exclusion most misread in the trade, and the answer is specific to your forms, your endorsements, and your state's law. Get it in writing, and get the actual policy language rather than a description of it.
How long does my completed-operations coverage run, and what happens to work I finished under a previous carrier?
Roof leaks surface years later. A gap between carriers on completed operations is invisible until a claim lands in it.
When a contract asks for additional insured on an ongoing and completed operations basis, primary and non-contributory, with a waiver of subrogation — can my current policy actually deliver all four, and at what cost?
These are contractual promises you make by signing. A certificate saying you have them is not an endorsement giving you them, and finding out at claim time is the worst possible moment.
What happens to my licence if a policy this credential is conditioned on lapses, even for a day?
In California a workers' compensation lapse suspends the licence, and work performed while suspended is treated as unlicensed. Other states differ. The answer determines how tightly you have to run the renewal calendar.
At premium audit, how are payments to subcontractors treated if I cannot produce a certificate for them?
In many arrangements an uninsured sub's payments are charged to your payroll, which turns a paperwork lapse into an audit adjustment sized by how much you paid that sub. This page cannot tell you whether your policy works that way — ask, in writing — but the fix either way, collecting certificates before mobilisation, costs nothing.
What would it take to get a bond line, what size, and what do you need from my accountant to underwrite it?
Bonding capacity is underwritten off financial statements and completed-job history you have to have already built. Asking two years early is the difference between being able to bid commercial work and watching it.
Who signs the indemnity agreement behind any bond, and does it reach me personally and my spouse?
It usually does, in a small contracting business. A bond is credit; the surety expects to be repaid. Knowing exactly who is on the hook is not a detail.

Get these in writing, at each renewal

Your classification code, rate, and experience factor, stated as numbers rather than described.
The declarations page and the endorsement list for every policy — not only the certificate.
Written confirmation of how completed operations is handled across a carrier change.
Copies of the additional-insured and waiver-of-subrogation endorsements you are relying on, by form number.
The general indemnity agreement behind any bond, with the signatories identified.
Renewal dates for every policy and every credential, on one list, with the conditional dependencies marked.

What goes wrong

What contractors get wrong about this, and how it failsSection link

These are not customer misconceptions. They are ones that circulate inside the trade, and each of them has a cost attached.

Common misconceptions

Common belief
“Licensed, bonded and insured” describes one credential.
What is actually true
It describes four unrelated instruments with four different beneficiaries, three different funding mechanisms, and — in most of the country — three different issuing bodies. Using the phrase is fine. Believing it is one thing is how a contractor ends up assuming the bond covers something the bond has nothing to do with.
Common belief
“My general liability covers my workmanship.”
What is actually true
A liability policy is built to pay third parties for what your operations do to them, and standard architecture treats your own defective work differently from everything else. South Carolina’s statute requires insurers selling there to treat faulty-workmanship damage as an occurrence — and writes the carve-out in anyway: “exclusive of the faulty workmanship itself.” Whether your specific policy reaches resulting damage to other property is a question for your policy and your jurisdiction, and is worth asking in writing before you need the answer.
Common belief
“Being bonded means my customer's money is protected.”
What is actually true
A licence bond is a statutory instrument sized by a government — $25,000 in California, $10,000 or $25,000 in Illinois depending on licence type — and its face amount is not a per-customer allowance. CSLB, describing California’s bond in its December 2022 Fast Facts sheet, put it as plainly as anyone: “The bond amount is not per job; it is the amount available for all the jobs a contractor takes on during the life of the bond.” Whether your bond works the same way is a question for the statute that requires it and for the bond form itself. It is not escrow, and it is not insurance for you: the Texas Department of Insurance describes the indemnity agreement behind a bond as requiring “that the surety (insurance company) is completely indemnified against any liability, loss, cost, attorney’s fees and expenses whatsoever that the surety shall sustain by having been surety on this bond.”
Common belief
“If I pay the crew on 1099s, the classification question is settled.”
What is actually true
The paperwork is one factor among many and it is not the decisive one. The IRS applies common-law rules across behavioural, financial and relationship categories and says plainly that there is “no ‘magic’ or set number of factors” and that “no one factor stands alone.” Separate tests apply under federal wage-and-hour law and under your state’s comp and unemployment systems, and they can reach different answers on the same worker.
Common belief
“I sent them a certificate, so I have proved I am covered.”
What is actually true
A certificate summarises policies as they stood the day it was printed. New York’s regulator: it “cannot confer new or additional rights beyond those set forth in the referenced insurance policy.” Texas’s: it “may not use terms that would alter, amend, or extend coverage.” It proves a policy existed. It does not prove one still exists, and it does not create anything.
Common belief
“A licence tells my customer I do good work.”
What is actually true
It tells them a government has a file on you and a way to discipline you, which is genuinely valuable and is the reason licensing exists. It is not a workmanship assessment. Denver’s two roof-covering certificates each require two years and twenty-four documented projects, and no examination at all. The argument that your work is good has to be made with your work.

How it actually fails

A policy lapse takes the licence with it: Where a credential is conditioned on coverage, the two calendars are one calendar and most people run them as two. California is explicit: failure to maintain workers’ compensation “will result in the license being suspended,” and “any work performed while the license is suspended is considered to be unlicensed.”What you can see: A renewal notice from a carrier that was never acknowledged; a board record showing a status change you did not initiate; a permit application refused for a reason nobody can explain on the phone.
The premium audit finds subcontractors on your payroll: Payments to subcontractors who cannot produce coverage are, in many arrangements, charged to your payroll at audit. The certificates were going to be collected later, and later arrived as an auditor.What you can see: An audit bill several times the expected adjustment; a request for certificates for people you engaged eighteen months ago; a sub who has since gone out of business and cannot supply anything.
The experience factor moves and nobody notices until the renewal: A claim from two years ago works through the rating calculation and lands as a multiplier on every payroll dollar going forward. The estimating sheet still carries last year’s burden rate, so every bid written after the change is short by the difference.What you can see: Gross margin drifting down across jobs that all look normal individually; a renewal premium that jumped without a change in headcount; a prequalification form asking for an EMR you have not looked at.
An additional-insured promise that the policy never delivered: A subcontract required additional-insured status on an ongoing and completed operations basis, primary and non-contributory. A certificate went out with the words typed into it and no endorsement behind them. The gap is invisible until a claim tests it.What you can see: No endorsement form numbers anywhere in your file; a broker who answers the question with a certificate rather than with a policy form; contract language you have never read against a policy you have never read.
Expansion across a state line without a credential: The regimes are not equivalent and rarely reciprocal. A licence that satisfies one state may be irrelevant in the next, where the requirement may sit at city level instead, or turn on the dollar value of the contract, or not exist.What you can see: A permit refused at the counter; a customer who checked and could not find you on a state register; a completed job in a state whose statute makes an unlicensed contract difficult to enforce.

Scope and limitations

It cannot tell you what your jurisdiction requires.
Six jurisdictions are described here, chosen to show that four incompatible regimes operate simultaneously in the United States.
Forty-five states and every other city are absent, and the six described can change their rules without this page knowing.
It cannot tell you whether any policy covers any loss.
Coverage is decided by the policy forms, the endorsements attached to them, the facts, and the law of the governing jurisdiction.
Nothing here is a coverage opinion, and none of it should be relied on as one.
It cannot tell you whether any worker is an employee or an independent contractor.
That determination is made by an agency or a court on your specific facts, under at least three different tests that can reach different answers.
It does not state the current federal wage-and-hour standard for independent-contractor status.
The Department of Labor's pages returned HTTP 403 to every request made while writing this page, so its current content could not be read and is therefore not described here.
That is a bot-blocking response rather than evidence the guidance does not exist.
It does not state any roofing-specific injury or fatality figure.
The one fatality statistic quoted here is OSHA's construction-wide statement and the 2024 BLS count OSHA attributes to it; BLS's own pages returned HTTP 403 to every request made while writing this page, so no rate, no ranking within the trade, and no comparison between trades is asserted anywhere.
It does not give a national figure for workers' compensation cost.
Washington is used because Washington publishes its state-fund rates by risk classification; the arithmetic is exact and the number is real, and neither travels to another state, because Washington rates on hours worked rather than on payroll.
It does not state California's current minor-work licensing threshold as a number.
The Board's own building-official guide, read on 27 August 2026, states $500 under Business and Professions Code section 7048, and the Board has separately published a 2024 bulletin describing an increase to that threshold which could not be opened.
Read the current statute rather than either document.
It makes no claim about North Carolina beyond the definition section of G.S.
87-1, or about Maryland beyond the Guaranty Fund page, or about Colorado state law at all — the Colorado Division of Professions and Occupations page returned HTTP 403.
Absence from this page is not evidence of absence in law.

Bond Requirements — contractor license bond, bond of qualifying individual, disciplinary bond
California Contractors State License Board (CSLB), Department of Consumer Affairs
That the California contractor licence bond is $25,000, at that amount since 1 January 2023 under Senate Bill 607, and that it is “filed for the benefit of consumers who may be damaged as a result of defective construction or other license law violations, and for the benefit of employees who have not been paid wages that are due to them” — that is, not for the benefit of the contractor.
California only. The page describes the bond as a licensing condition; it does not describe the indemnity agreement between a principal and a surety, which is a private contract and is not published by the Board.
Fast Facts — A Guide to Contractor License Bonds
California Contractors State License Board (CSLB), Department of Consumer Affairs / Rev. 12/22
That a California contractor licence bond is not a per-customer allowance: “The bond amount is not per job; it is the amount available for all the jobs a contractor takes on during the life of the bond. Once the bond has been depleted, a contractor must purchase a new one for the license to remain in effect.”
California only, and it describes the CSLB licence bond specifically — not bonds generally, and not any bond required by another state, a city, or a construction contract. CSLB has since published a 2025 consumer-facing rewrite of the same Fast Facts title which does not repeat this sentence, so the wording is quoted here with the December 2022 revision date it carries. It says nothing about the indemnity agreement between a principal and a surety.
Workers' Compensation Requirements for licensees
California Contractors State License Board (CSLB), Department of Consumer Affairs
That C-39 Roofing contractors “are required to carry workers' compensation insurance or a valid Certification of Self-Insurance, whether or not they have employees” under Business and Professions Code section 7125; that a C-39 may not file the exemption other classifications may file; that failure to maintain coverage “will result in the license being suspended”; and that “any work performed while the license is suspended is considered to be unlicensed.”
California only, and it describes the licensing consequence rather than the coverage obligation under California's labour code, which is administered by a different agency.
Building Official Information Guide
California Contractors State License Board (CSLB), Department of Consumer Affairs
That Business and Professions Code section 7048 exempts minor work from licensure below a statutory threshold, stated on this page as an aggregate contract price of less than $500; and that section 7031.5 requires a jurisdiction issuing a permit to obtain a signed statement that the contractor is licensed and that the licence is in force.
The threshold in section 7048 has been amended by later legislation, and CSLB has published a 2024 industry bulletin about an increase which could not be opened for this page. This guide's $500 figure may therefore be superseded. Read the current text of section 7048.
Illinois Roofing Industry Licensing Act, 225 ILCS 335
Illinois General Assembly / 225 ILCS 335
That Illinois licenses roofing as its own trade; that it is “unlawful for any person to engage in the business of providing professional roofing services … without having been duly licensed”; and the statutory definitions of a limited roofing licence (“roofing residential properties consisting of 8 units or less”) and an unlimited roofing licence (residential, commercial and industrial). Also that the Act requires a licensed roofing contractor to designate a qualifying party who participates in day-to-day operations and who must pass an examination authorised by the Department, with the technical portion differing between the limited and unlimited licences.
Adopted Illinois law. It says nothing about any other state, and the Act is amended from time to time — the General Assembly's own site is the version to check.
68 Ill. Adm. Code Part 1460 — Illinois Roofing Industry Licensing Act rules
Illinois General Assembly, Joint Committee on Administrative Rules
The Illinois insurance and bond conditions: liability cover of $250,000 per occurrence for property damage and $500,000 per occurrence for personal injury or bodily harm with 30 days' notice of cancellation; surety bonds of $10,000 (limited) and $25,000 (unlimited) with 60 days' notice; and that a workers' compensation applicant may supply either proof of coverage or self-insurance or “a certifying statement that the applicant has no employees.”
Administrative rule, which changes more often than the statute above it. Illinois only.
North Carolina General Statutes § 87-1 — definition of “general contractor”
North Carolina General Assembly
That North Carolina's general contractor licensing requirement is defined by the cost of the undertaking — work “where the cost of the undertaking is forty thousand dollars ($40,000) or more” — rather than by trade, and the exemptions listed in that section.
Only this definition section was read. This page makes no claim about North Carolina's other licensing, insurance or bonding statutes, or about the licence tiers and their project-value caps, which are in other sections.
Guaranty Fund Frequently Asked Questions
Maryland Home Improvement Commission, Maryland Department of Labor
That Maryland uses a state Guaranty Fund “supported by licensed contractors, who pay a Guaranty Fund assessment” at licensing and each renewal; that it reimburses a homeowner's “actual loss” from unworkmanlike, inadequate, incomplete or abandoned work; the $30,000 per-claimant cap or the amount paid, whichever is less; the $250,000 aggregate against one contractor; the exclusion of consequential damage, attorney's fees and court costs; and that the Fund “will not reimburse a claimant for money paid to an unlicensed home improvement contractor.”
This page describes the Fund, not the licensing requirements themselves. Nothing here should be read as a statement of what Maryland requires of a licensee.
Programs Licensed and Regulated by TDLR
Texas Department of Licensing and Regulation
That roofing is not among the programs TDLR licenses and regulates. The full list was read; the only entry beginning with R is Residential Solar Retailers.
TDLR is one Texas agency. Its list is evidence that TDLR does not license roofing, not proof that no Texas authority does; municipal registration exists and was not verified for this page.
Workers' compensation — employer resources
Texas Department of Insurance, Division of Workers' Compensation
That “in Texas, private employers can choose to carry workers' compensation insurance coverage, but it is not required in most cases”; that a non-subscriber must report that it has no coverage and must report work-related injuries with more than one day of lost time, illnesses and deaths; and that coverage “limits liability if an employee sues your business for damages,” except where gross negligence results in a fatality.
Texas only, and it is the single clearest counter-example to the assumption that workers' compensation is universally mandatory. It does not describe how any other state treats the question.
Roofing and insurance: know the law
Texas Department of Insurance / Last updated 24 March 2025
That “Texas doesn't allow a roofer or contractor to act as a public insurance adjuster on insurance claims if they're also doing the work”; that “it's also illegal in Texas for a contractor to offer to waive, rebate, or absorb a property policyholder's deductible”; and that contracts of $1,000 or more must carry a notice that the policyholder must pay the deductible.
Texas rules only. Other states regulate roofers' conduct inside insurance claims differently, and some not at all.
Certificates of insurance — frequently asked questions
Texas Department of Insurance / Page dated 31 October 2022
That a certificate “may not use terms that would alter, amend, or extend coverage that is provided in the insurance policy”; that a certificate holder “may not use the ‘Certificate Holder’ box to imply or confer any new or additional rights beyond what the policy or any executed endorsement of insurance provides”; and that a holder may ask the agent about specific policy language or request a copy of the policy.
A Texas regulator's description of Texas requirements for certificates issued in Texas. The underlying principle is widely shared but this document is not evidence of any other state's rule.
OGC Opinion No. 11-01-08: Certificates of Insurance
New York State Department of Financial Services / 31 January 2011
That “a certificate of insurance is a document that summarizes the terms, conditions, and duration of an insurance contract, but it is not the contract itself,” and that it “cannot confer new or additional rights beyond those set forth in the referenced insurance policy.”
A New York general-counsel opinion, which is guidance on New York law rather than a nationwide rule, and which predates later New York statutory activity on certificates.
South Carolina Code § 38-61-70 — commercial general liability insurance
South Carolina Legislature / Effective 17 May 2011
That a commercial general liability policy offered for sale in South Carolina must define “occurrence” to include an accident and “property damage or bodily injury resulting from faulty workmanship, exclusive of the faulty workmanship itself,” and that the section “is not intended to restrict or limit the nature or types of exclusions from coverage” an insurer may include. Effective 17 May 2011.
Adopted South Carolina law and nothing more. It is cited here as evidence that the treatment of a contractor's own defective work was contested enough to legislate on, and that even a statute written in contractors' favour carved the faulty workmanship itself back out. It is not authority anywhere else, and it is not a coverage opinion for any policy.
Independent contractor (self-employed) or employee?
Internal Revenue Service / Page last reviewed 19 May 2026
The three common-law categories the IRS uses — behavioural control, financial control, and type of relationship; that there is “no ‘magic’ or set number of factors that ‘makes’ the worker an employee or an independent contractor and no one factor stands alone”; and that Form SS-8 asks the IRS for a determination, which the agency says takes at least six months.
This is the federal tax test only. It does not decide status under federal wage-and-hour law, or under any state's workers' compensation or unemployment statute, and those tests can reach different answers on the same worker.
29 CFR 1904.39 — Reporting fatalities, hospitalizations, amputations, and losses of an eye
Occupational Safety and Health Administration, U.S. Department of Labor
The eight-hour window for reporting a work-related fatality and the twenty-four-hour window for an in-patient hospitalisation, an amputation, or an employee's loss of an eye; and the three reporting routes — the nearest OSHA Area Office, 1-800-321-OSHA, and the reporting application on OSHA's website.
Applicability depends on the employer and the work, and states operating their own OSHA-approved plans may impose additional or different requirements. Nothing on this page is a compliance determination for any employer.
Bond Resources — surety and fidelity bonds
Texas Department of Insurance
The three-party structure quoted on this page — “the Surety (insurance company) that guarantees the faithful performance of the Principal (sometimes referred to as the Obligor) to the Obligee the owner or entity that is expecting an obligation to be completed” — and the regulator's description of an indemnity agreement as requiring “that the surety (insurance company) is completely indemnified against any liability, loss, cost, attorney's fees and expenses whatsoever that the surety shall sustain by having been surety on this bond.”
A Texas regulator's general explanation of surety bonding. It is not the text of any particular indemnity agreement, and it does not state who a given surety will require to sign one. Read your own agreement for that.
Stop Falls — National Safety Stand-Down to Prevent Falls in Construction
Occupational Safety and Health Administration, U.S. Department of Labor / 2024 BLS data as cited by OSHA
OSHA's statement that “falls are the leading cause of death in construction,” and the figure it attributes to BLS for 2024: 389 fatal falls to a lower level out of 1,034 construction fatalities.
Construction-wide, not roofing-specific. It is not a fatality rate, it is not a ranking of hazards within the roofing trade, and this page makes no roofing-specific fatality claim. BLS's own pages returned HTTP 403 to every request made while writing this page, so the underlying series was not read here.
2026 Rates per Hour Worked for State Fund firms, by business type and class code
Washington State Department of Labor & Industries / 2026 rate year
Risk classification 0507, Roof Work — Construction and Repair: a 2026 composite base rate of $5.7930 per hour worked against $5.8440 in 2025, a change of −1%; the building construction and trades composite of $2.5106; the note that base premiums are calculated assuming an experience factor of 1.0000 and standard premiums an average factor of 0.91; and the definition of a full-time employee as 1,920 hours worked.
Washington State Fund rates only. The document does not price any individual employer's premium, does not apply to self-insured employers, and does not describe how any other state rates workers' compensation. Washington rates on hours worked; most states do not.
Rates for Workers' Compensation
Washington State Department of Labor & Industries / 2026 rates
That Washington publishes hourly rates by classification code and expected loss rates “in dollars per worker hour”, that an experience factor applies, and that “the composite rate is the sum of the individual base rates assuming an experience factor of 1.0” — the basis on which the arithmetic in the cost section is built.
The page confirms the rating basis and the existence of the experience factor; it does not explain how the factor is calculated, which is a question for L&I directly.
Specialty Class D Certificates — contractor licensing
City and County of Denver, Community Planning and Development
That Denver issues its own roofing certificates: “Roofing-Shingles – Residential Only” for “installation of residential only roofing systems” and “Roof Covering/Waterproofing – Commercial & Residential” for “installation of commercial and residential roof coverings, including valleys, gutters, downspouts and waterproofing”, plus a green-roof-only certificate; that each requires two years of experience and at least twenty-four documented projects from different months; and that no test is required.
One city. It is cited as evidence that municipal roofing credentials exist with their own requirements, not as a statement about Colorado state law — the Colorado Division of Professions and Occupations page returned HTTP 403 and was not read.
