You can measure any roof footprint for free in 3 minutes using Google Earth's built-in measure tool. Works on desktop and mobile. No EagleView needed for a quick estimate.
Go to earth.google.com on your phone or laptop. Or open the Google Earth app on iPhone/Android.
Type the property address in the search bar (top left on desktop, magnifying glass icon on mobile). Hit enter. Google Earth zooms you to the property.
Press R on desktop, or tap the compass icon on mobile, to reset to a straight-down view of the roof. You should see the whole roof from above.
Click the ruler icon on the left toolbar (desktop), or tap the 3-dot menu → Measure (mobile).
Click each corner of the roof footprint, working around the perimeter. When you close the shape, Google Earth gives you the area in square feet.
Google Earth gives you the footprint (flat area). For actual roof area, multiply by pitch:
Back on the Calc tab, enter the L × W of each roof section in Roof Sections, set the pitch, and the calculator handles the rest with waste factor built in.

Built by Will Brambila, owner of BSR Constructions LLC. A family-owned roofing and exteriors company in Seattle, WA. Founded with my brother Art, we serve Pacific Northwest homeowners and contractors with the same focus every day. Do the work right. Treat people fair. Build something that lasts.
Every day on jobsites, contractors waste time doing math on the back of an envelope. Estimates take hours that should take minutes. Numbers get fuzzy. Profit gets lost in guesswork.
I built this tool to fix that for my own crew. Then I figured I'd share it.
It's a calculator I actually use. On roofs. In driveways. In front of homeowners. I wanted something that gave me a real bid number in 60 seconds without pulling out a laptop or doing 12 steps of math on a calculator app.
If you're another small business owner, contractor, or estimator out there grinding it out, this is for you too. Free. No login. No email capture. Just open it and use it on the jobsite.
