Built for roofing, solar & gutter teams
How it works

From address to report in three steps.

No site visit, no scheduling, no waiting on a third party. The whole measurement happens remotely while you stay at your desk.

01

Enter the address

Type any U.S. residential or commercial address. That's the entire input — no coordinates, no forms.

02

We pull the data

Solar81 fetches high-resolution aerial imagery through Google's Solar API and reconstructs the roof, facet by facet.

03

Get measurements + report

Area, pitch, and facets render instantly, plus a branded PDF you can attach to a bid or hand to a crew.

What you get

Everything you'd send a crew up a ladder for.

Roof area

Total and per-facet square footage, pitch-corrected so you get true surface area — not just the footprint.

Pitch & slope

Predominant and per-plane pitch in rise:run and degrees, for accurate material math.

Facets & orientation

Every roof plane segmented with its pitch, compass facing, and area — plus an estimated roofline length for gutter runs.

Photorealistic 3D view

Flip any report into Google's photorealistic 3D — the homeowner sees their actual house, rotatable, from every angle.

PDF report

A clean, branded document ready to attach to a bid or hand off to your install crew.

Instant turnaround

Results in about a minute — not the hours or days a report vendor or site visit takes.

Measurements are estimates derived from aerial imagery — built for quoting and qualifying. Field-verify before final material orders. 3D view availability varies by location.

Pricing

A fraction of what a report or site visit costs.

Quote-ready measurements at remote-software pricing — run a report on every lead, not just the jobs you've already won.
