You can measure your roof accurately from your couch in about 60 seconds. Enter your address into a satellite roof measurement tool, trace the outline of your roof (or let AI do it), and you get your total square footage, roofing squares, and even gutter length — no ladder, no tape measure, no waiting for a salesperson.
We built a free roof measurement tool that does exactly this for any home in the Seattle Eastside area. Here's how satellite roof measurement works and how to get an accurate number.
Satellite roof measurement uses high-resolution aerial imagery with a known scale — every pixel represents a precise number of inches on the ground. When you trace your roof's outline on the image, the tool converts the traced area into real square footage using that scale, then applies a pitch multiplier to account for your roof's slope.
That last step matters: a roof is bigger than the house footprint beneath it. A 2,000 sq ft footprint under a moderate 6/12 pitch roof is actually about 2,240 sq ft of roofing surface.
Within a few percent of a physical measurement for most homes — accurate enough for realistic budgeting and quotes. Our tool also cross-checks your trace against Google's AI roof analysis (the same data used for solar panel planning), so you get two independent measurements. Final numbers are always verified on-site before any material order.
One square = 100 square feet of roof surface. A 2,400 sq ft roof is 24 squares. Contractors price in squares, so knowing yours instantly makes every quote you receive easier to sanity-check. Full breakdown here: How Many Squares Is My Roof?
Works on any phone or computer. No account, no obligation — you get your numbers and a professional PDF report on the spot.
Is a free satellite roof measurement as good as an EagleView report?
For homeowner budgeting, yes — both use aerial imagery and the numbers land close. Paid reports add certified accuracy guarantees contractors use for material orders. Full comparison here.
Can I measure my gutters from satellite too?
Yes. Our tool measures gutter runs, hips, ridges, and valleys in linear feet — just draw the lines along the eaves.
Do I need to know my roof pitch?
No. Pick from simple visual options (most Northwest homes are "moderate"), and the tool handles the math. The report shows exactly which multiplier was applied.
Measure your roof free from satellite — square footage, gutters, and a real cost range in about a minute. Then get a free, no-obligation estimate from Roof4Life. Serving Seattle, Bellevue, Kirkland & the entire Eastside since 2012.
