Roofing Cost Estimator

Preparing a roof repair, callback, or quick bid? Roofing Cost Estimator turns roof size and pitch into roofing squares, shingle bundles, underlayment rolls, waste, and a materials-only cost estimate before you call a supplier. Use it to: - enter rise, run, roof width, roof length, overhang, and waste - calculate roof area, roofing squares, pitch angle, and rafter length - estimate shingle bundles from the coverage and waste assumptions you enter - add bundle price, underlayment roll coverage and price, and an accessory allowance - see bundle count, underlayment rolls, materials-only total, and cost per roofing square - save repeat roof profiles as presets and reopen recent estimates from local history - share the current materials-only estimate with the input assumptions behind it Built for roofers, remodelers, and owner-builders preparing a supplier call or early material estimate. It works offline with no account, ads, subscription, analytics SDK, cloud sync, or server dependency. This is a field estimation aid, not an engineering certificate, code-compliance decision, permit approval, labor quote, tax or delivery estimate, or guaranteed bid. Verify geometry, product coverage, waste, local requirements, and supplier pricing before ordering.
