This free tool from Roof4Life, a Kirkland, WA roofing contractor, measures your roof from satellite imagery. Enter your address, trace your roof, and get the total roof area with pitch applied, your roofing squares, and gutter, ridge and valley lengths in a few minutes, with no ladder and no sales visit.
Yes. Measuring your roof costs nothing and does not require a site visit or a sales appointment.
You enter your address, the tool loads a satellite image of your home, and you trace each roof section. It calculates the area of each section, applies the roof pitch, and totals it into square feet and roofing squares.
One roofing square equals 100 square feet of roof surface. Roofers price materials and labor by the square, so knowing your count helps you compare bids.
It is accurate enough for budgeting and comparing contractor bids, but accuracy depends on image quality, tree cover and how carefully the roof is traced. A contractor will still verify measurements on site before a final price.
A satellite image shows the roof from directly above, so it understates the true surface area of a sloped roof. Pitch typically adds about 12–30% to the flat footprint.
The tool works on any address with clear satellite imagery. Roof4Life’s cost ranges and installation services cover Kirkland, Bellevue, Seattle and the Eastside.
