Don't let missing field data hold up your design.

When satellite imagery can't see the roof, we put a technician and a drone on site. In-person site surveys, PE stamped engineering and inspection, so design doesn't wait on field data. All 50 states.

In-person surveys, PE stamped engineering and inspection. All 50 states. Nationwide, 500+ technicians.

  • Bring us one project. Pick the survey, engineering or inspection you need.
  • Not a pilot. An operation. 50,000+ surveys completed.

How it works

  1. Book a callScope the site with the team.
  2. On-site or drone captureA technician on the property and/or aerial capture to a fixed spec.
  3. Processing and QAPhotos sorted and mapped; findings classified against the as-built record.
  4. DeliverableData and findings in the client portal, ready for design, permitting, or remediation.

What you get

  • Photos sorted and mapped.
  • A measured record for design and engineering.
  • Inspection imagery and located findings where that service applies.
  • One partner from first site visit through inspection.

Where design stalls

  • Imagery out of date in rural areas
  • No usable satellite imagery for the property
  • Missing field data holds up design

What we put on site

  • A technician on the roof
  • A drone where the roof can't be reached
  • Data tied to the site
The problem

The survey is a rounding error in the budget
and it decides the whole project.

A measurement taken from a driveway. A roof plane estimated off satellite imagery. An electrical panel nobody photographed. None of it looks like a problem until it is one, three weeks later, with a crew already on site.

It surfaces late

Bad field data never fails at the survey. It fails at design, at permit, at inspection, or on the roof, where every hour costs ten times more and the customer is watching.

It compounds downstream

One wrong azimuth becomes a redesign, a re-permit, a re-schedule and a change order. The original error costs nothing. The chain reaction is the invoice.

Nobody is measuring it

Revisits get logged as scheduling. Redesigns get logged as engineering. The cost is real and continuous, and it almost never appears on a line item anyone owns.

Where you operate

Pick your ground. We'll show you
exactly how the work runs.

The failure mode is different at every scale, and so is the fix. Choose everything that applies; plenty of our customers run two or three of these at once.

Select one or more. The sections below adapt, and your calculator gets tuned to match.

Bring us one project. We'll survey it, deliver it, and you can compare it against whatever you're doing now.

LiDAR topography

Centimetre-grade terrain capture before earthwork commits you to a number. Grading volumes, drainage paths and racking layout come off measured ground rather than a desktop estimate.

Why we get better and they don't

Every survey we run makes
the next one sharper.

A survey company sells you hours. We're running a data flywheel: every site we capture becomes labelled training data, every model improvement makes the next capture faster and more accurate, and that speed wins more surveys, which produces more data. It compounds, and it can't be bought. Only accumulated.

99.99%data accuracy
01
Capture
A technician or a drone captures a site to a fixed spec: the same fields, the same angles, the same photo discipline, every time.
02
Label
Every capture is verified against what was actually built. Right and wrong both become ground truth, which is the part most datasets never get.
03
Train
Computer-vision models learn roof geometry, obstruction detection, thermal signatures and defect classes from real installed outcomes.
04
Automate
What a person measured last year, a model measures this year: faster, cheaper, and without the variance between technicians.
05
Compound
Faster and more accurate wins more surveys. More surveys produce more ground truth. The gap widens every quarter.
New · The Solar Survey AI platform

Every roof we touch becomes
a live, measured model.

Every site we capture now lands in your own client portal as working data: photos sorted and mapped, every roof section measured in 3D, and shade calculated for every hour of the year.

Live

Client portal

Every delivered site in one place: sorted photo sets, a photo map, the model and the report.

Live

3D roof model

Pitch, azimuth, area and edges for every roof section, each with its tolerance.

Live

Shading analysis

Solar access, TOF and TSRF per roof section, on typical-year NREL weather.

Next

Predict & protect

Remote shade reports, P50 / P90 production estimates and performance monitoring.

Now in the web platform: follow your company's survey pipeline, add company capture checklists and discuss specific measurements or photographs. Explore contextual 3D site maps, where coverage is available, alongside confirmed equipment callouts, visual sun playback and preliminary electricity-use estimates. Explore the client workspace → The initial Sales Studio adds pre-survey concepts, a separate roof designer where source coverage is available, illustrative cash/loan comparisons and branded proposal PDFs.
