Satellite roof measurements, without the wait or the per-report fee
Traditional aerial measurement reports cost money per address and can take hours or days to come back. Rooftops AI measures the roof the moment you type the address: high-resolution satellite imagery is combined with 3D elevation data to compute each facet's true plane area and pitch — not just the footprint. You get squares with waste factor, ridge, hip, valley, and eave lines, and a confidence score, while you're still in the driveway.

Roofing squares calculator
Convert roof area to squares and bundles, with waste included.
Simple gable roofs run 8-12% waste; cut-up hip roofs with valleys run 15-20%. Rooftops AI recommends a waste factor per roof based on its measured complexity.
How it works
Enter the address
Search any US address. We pull current high-resolution satellite imagery and Google's 3D elevation model for the parcel.
AI measures every facet
The roof is segmented into facets, each measured for true area and pitch. Ridges, hips, valleys, and eaves are classified and drawn on the imagery.
Use it on the job
Get total squares with waste factor, a materials takeoff, and an estimate range — export the PDF or convert it into a proposal in one click.
What you get
True plane area, not footprint
Pitch factors are applied per facet from 3D elevation data, so a cut-up 8/12 roof doesn't get measured like a flat rectangle.
Line-by-line roof geometry
Ridge, hip, valley, and eave lengths are mapped automatically — the numbers you need for ridge cap, ice-and-water, and trim orders.
Confidence you can defend
Every report carries a confidence score, and complex or heavily tree-covered roofs are flagged for on-site verification instead of silently guessing.
Unlimited under your plan
No per-address invoice. Run measurements on every lead that comes in, not just the ones you're already confident about.
How satellite roof measurement works
Modern satellite measurement combines high-resolution aerial imagery with elevation data to model the roof in three dimensions: footprint, pitch per facet, ridge and valley lines, and total surface area including the slope correction that flat-map tools miss. A roof that measures 2,000 square feet on a flat map is roughly 2,240 square feet of actual surface at a 6/12 pitch and over 2,500 at 9/12. Skipping the pitch correction is the classic way manual estimates come up a full square or two short.
Rooftops AI cross-checks its AI measurement against independent geometry for the same address, and every report states its confidence and flags anything worth verifying on site. Trees over a corner, new construction, and complex intersecting rooflines are the honest failure modes of any aerial method, so the report tells you when it is unsure instead of pretending.
Accuracy, and what to verify on site
For bidding purposes, aerial measurements on typical residential roofs land within a few percent of a tape pull, which is inside the waste factor you carry anyway. The measurements that most affect the order (total squares, ridge and valley footage, predominant pitch) come through reliably. What deserves an on-site check: layers (aerial can't see a second layer under the top one), decking condition, and anything under heavy tree cover.
The economics are simple. A measurement service that charges per report and takes hours makes you ration measurements to serious leads only. When measuring is 30 seconds and effectively free, you measure every lead, every canvass door, and every referral while they are still on the phone, and you show up to the appointment already knowing the roof.
From measurement to material order
A measurement becomes an order through squares, waste, and linear items. Field shingles come from total area plus a waste factor matched to the roof's cut-up: 8 to 12 percent on simple gables, 15 to 20 on hip-heavy or valley-heavy roofs. Linear items come from the measured edges: drip edge from eaves and rakes, starter from the same, dedicated ridge cap from ridge and hip lengths, ice and water from eave runs and valleys where code requires it.
Rooftops AI recommends a per-roof waste factor from measured complexity and facet count rather than a flat 10 percent guess, and its material list carries the linear quantities so the order matches the roof instead of a rule of thumb. Order short and you pay for a second delivery; order long and margin sits on a pallet in the garage.

Frequently asked questions
How accurate are satellite roof measurements?
Rooftops AI combines high-resolution satellite imagery with Google's 3D elevation data to measure each facet's true area and pitch. Every report includes a confidence score, and roofs with heavy tree cover or unusual geometry are flagged for field verification.
How fast do I get the measurements?
About 30 seconds from typing the address. There's no ordering queue and no per-report turnaround time.
Does it include pitch and waste factor?
Yes. Predominant and per-facet pitch are computed from elevation data, and squares are reported with a waste factor appropriate to the roof's complexity.
How much does it cost?
Your first 3 full roof reports are free — no credit card. Paid plans start at $30/month billed annually ($50 month-to-month) with 10 reports included.
