Roof area & pitch
Transparent geometry, mixed roof planes, squares, and a printable result.
Calculators & worksheets
A useful estimate names what it does not know.
Use measured inputs, check the assumptions, and keep a copy of the result. Start with roof geometry or the scope of actual proposals.
30-second answer
Can a roofing calculator tell me what my roof will cost?
Area arithmetic can help explain a quote, but it cannot establish a local installed price. Our former cost beta has been withdrawn while its rates and scope are verified. Compare measured proposals and their exclusions instead.
Available tools
Measure the roof. Compare the scope.
These tools work in your browser without an account. They do not upload your inputs, and each provides a print option.
Calculate roof area, pitch & squares
One plane or mixed slopes; horizontal area or measured surface; square feet or square meters; separate ordering waste.
Compare roofing quote scope
Put two written proposals side by side and identify missing answers before comparing prices.
Use the right evidence
A calculation is only as useful as its inputs.
Start with plans or a professional measurement report. Do not climb onto a roof to fill out a tool.
Quote comparison
Manual scope comparison with prices, allowances, exclusions, and questions. No automatic winner.
Replacement cost
Numerical cost outputs are paused. The tool has no active, scope-matched pricing dataset. Use written project proposals.

The methodology records what the tools calculate, why cost outputs were removed, and which evidence is needed before more advanced models can be released.
