Roofing cost calculator FAQ
Is this a contractor quote?
No. It is a planning calculator. A site inspection and written contractor proposal are still required for a binding price.
What is a roofing square?
A roofing square equals 100 square feet of roof area. Our Methodology page cites the GAF source used for this definition.
Why does the calculator show a range?
Actual roofing bids vary by labor market, material, roof access, pitch, tear-off scope, permit requirements and project complexity.
