How the estimate is calculated
- Footprint. The house outline from OpenStreetMap, or your living area plus garage.
- Roof area. Footprint plus eave overhang, times the pitch factor (1.118 for a 6/12 roof).
- Price. Roof area times the 2026 installed price range for each material, adjusted for complexity and tear-off layers. Sources.
Frequently asked questions
How much does a new roof cost in 2026?
For a typical 1,900 sq ft one-story home with a two-car garage (about 29 squares of roof), architectural shingles run about $11,600–$26,000 installed and standing-seam metal about $28,900–$52,000. Your size, pitch and local labor move the number.
How does RoofGenius estimate my roof from an address?
It finds the house outline in OpenStreetMap, adds the eave overhang, multiplies by the pitch factor to get true roof area, then prices that area with 2026 national installed ranges for each material.
Is the estimate free, and will anyone call me?
It is free with no sign-up. We don't ask for a name, email or phone number, so nobody calls you.
How accurate is an address-based roof estimate?
Close enough to budget and compare bids. A map outline can be a few feet off, and it cannot see roof damage or extra layers. A roofer measures on site before a final price.

Why RoofGenius
- Shows the math. Formulas, worked examples and tables on every page, so results can be checked by hand.
- No signup. Calculators run in your browser. The one exception is the address lookup, which sends the address to free public map services to find the house, and nothing else.
- Roofing calculators since 2001. RoofGenius has published roof pitch and estimating tools for over two decades, and the site was rebuilt from scratch in 2026.
