Find your house, click around the edge of your roof, and we'll work out the approximate area. It takes about a minute and makes your price indication a lot more accurate.
Start typing your address and pick it from the list, or just zoom and drag the map to your house.
Click each corner of the roof edge, eaves included (the overhang past the walls). Three or more corners, then press Finish section. Separate garage or patio roof? Finish the first shape, then trace the next.
Satellite sees your roof flat from above. The slope adds area, so pick the closest match.
Approximate only. It's plenty for a price indication; the final quote is always based on an on-site measure.
