Hiring & quotes
The lowest total is not always the same job.
Turn proposals into an apples-to-apples comparison of scope, materials, quantities, details, allowances, responsibilities, warranties, and price.
30-second answer
How do I compare roofing quotes fairly?
Compare the work before the total. A bid that omits deck allowances, flashing replacement, ventilation, permits, disposal, or warranty responsibilities can look cheaper because it defines less.
Read the proposal
Six words that quietly shrink a scope.
Most bid gaps are not price differences. They are definition differences, and they hide behind familiar words. Ask the follow-up before you compare totals.
- “As needed”
- Ask insteadHow many square feet of deck replacement are included before it becomes a change order, and at what unit price after that?
- “Standard”
- Ask insteadStandard by whose definition? Name the product, the thickness or weight, and the fastening pattern.
- “Per code”
- Ask insteadWhich adopted code edition, and which local amendments? That answer belongs to the jurisdiction, not to the bidder.
- “Allowance”
- Ask insteadWhat quantity does the allowance cover, and what is the price per unit once it runs out?
- “Lifetime warranty”
- Ask insteadWhose lifetime, whose warranty, what is prorated, what voids it, and who answers a claim in year twelve?
- “Includes cleanup”
- Ask insteadMagnet sweep, gutters, landscaping—and who pays if something is damaged during the work?
A written answer makes the proposed scope easier to compare. If it changes the work or the price, request a revised proposal so every bidder is being evaluated against the same defined project.
