What would a new roof cost? Start with your address.

No. It’s a ballpark from aerial data, so you know roughly what you’re looking at before anyone comes out. Houston’s free estimate gives you the exact, itemized price, and that’s the number we stand behind.

The Commonwealth of Virginia maps the outline of every building in the state. We take the outline of your house, adjust for the slope of the roof, and price it from our own price book. In Henrico and Chesterfield, county tax records help us judge how steep and cut-up the roof is.

We tested it against 72 roofs we’d had professionally measured. About 9 in 10 came within 20% of the real roof area. That’s why we show a range, not a single number.

Some roofs fool a satellite: flat or low-slope sections, very large or very complex roofs, or an address that sits between buildings. In those cases a guess would mislead you, so we don’t give one. Houston will measure it in person, free.

Rotten decking under the old shingles, a second layer to tear off, chimneys, skylights, steep pitches and how hard the roof is to get to. None of those show up from above.

Not unless you book or ask us to email you the ballpark. The aerial photo is fetched by our server, so your address never ends up in a link. If you email yourself the ballpark, we keep your email, ZIP and the range, not your street.
