About FreeRoofingCalculators.com

Draft: the owner's legal business name will be added here before launch.

FreeRoofingCalculators.com is a set of free roofing calculators: roof area and squares, roof pitch, rafter length, shingle bundles, metal roofing panels, underlayment, roofing nails and a cost estimate that uses only your own prices. Everything runs in your browser, works on a phone and needs no sign-up.

Who runs it

The site is owned and operated by FreeRoofingCalculators.com, a small U.S. publisher of free online tools. We are not a roofing contractor or supplier and we don't sell roofing.

How the numbers are made

The formulas and manufacturer coverage figures are listed on the methodology page. Coverage figures come from published data sheets and product pages. The math has automated tests, including checks against published rafter tables.

How the site makes money

We may show display ads below the results. We may later link to roofing lead-generation or quote services; if we do, those links will be labeled and explained on a disclosure page. Payments never change the math.

Estimates, not quotes

Results are planning estimates. Your roof, your product and your installer all change the real number. See the disclaimer. Questions or a correction? Contact us.
