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 and satellite imagery through Google's Solar API and reconstructs the roof.

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, with waste-factor allowances built in.

Pitch & slope

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

Facets & lines

Every plane segmented, with ridge, hip, valley, eave, and rake lengths labeled.

3D roof model

An interactive 3D reconstruction you can rotate, inspect, and share with the homeowner.

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.

Pricing

A fraction of what a report or site visit costs.

Same measurements you're paying for today — at remote-software pricing.

"We dropped EagleView for everything but the trickiest commercial jobs. Solar81 gives my estimators numbers before the homeowner's even off the phone."
DM [Customer name]Owner · [Roofing company]
"Our solar designers used to wait days on survey data. Now it's part of the intake call. The 3D model alone has cut our revisions in half."
RK [Customer name]Design lead · [Solar EPC]
"At a few dollars a report, we run one on every lead now — not just the ones we've already won. It's changed how we qualify jobs."
