Based on our September 2026 release

AI Instant Reports

One test. Three honest numbers.

Every model release is graded the same way, month after month, and every release publishes the same three headline numbers. These grade our AI Instant Reports. Human Certified Reports are checked and signed off by a person, so they are highly accurate every time and are not part of the grading.

88%

Order-Ready Rate

88 out of 100 AI Instant Reports pass every check at once: roof size, every edge length, and steepness all close enough to order materials without anyone getting on the roof.

2.3%

Bust Rate

The rare AI Instant Reports where the roof size came back off by more than 10%. We publish these instead of hiding them in an average.

96%

Coverage

Out of 100 addresses we try, 96 come back with an AI Instant Report we can hand you. The rest are roofs we simply cannot measure, usually because the imagery is too old or too blurry, and we count those as misses instead of quietly dropping them.

How often each measurement is right

These are our AI Instant Report scores. A measurement counts as right when it is close enough that it would not change what you order or what you bid.

Roof size (squares)

The total area of the roof, the number that sizes the shingle order

94%

Steepness (pitch)

How steep the roof is, which sets the labor tier

95%

Ridges

The peak lines at the top, for ridge cap and vent

93%

Eaves

The bottom edges where gutters hang

91%

Facet count

How many separate surfaces the roof breaks into

90%

Rakes

The slanted edges at the gable ends

89%

Hips

The sloped outside corners running down from the peak

85%

Valleys

Where two slopes meet and water runs

83%

Graded against reports measured and certified by human experts. Every number on this card is from our September 2026 model release and covers AI Instant Reports only. Human Certified Reports sit outside the card: a person checks and signs off on each one, so they are highly accurate every time.

Human Certified Measurement Reports

Want a human to measure it? Get a Human Certified Report.

A Human Certified Measurement Report is our instant measurement checked line by line and certified by a human expert.

  • Highly accurate every time, because a person checks and signs off
  • Same fast measurement, certified by a human expert
  • Built to be order-ready, just like our AI Instant Reports
  • The double check when a confidence score on any line looks low
  • The certification our AI is graded against, so the standard never drifts

The human yardstick

Here is the part most measurement companies skip: we check how far apart two human experts land when they measure the same roof. That gap is the fair definition of perfect. Our AI's goal is to sit inside that human-vs-human range, and on its most confident reports, it already does.

That is also why the certified reports matter so much: they are the answer key our AI is tested against, release after release.

That is also why certified reports are not on the report card. There is no percentage to publish when a person checks every line and puts their name on it.

The rules we hold ourselves to

Accuracy claims are easy. Ours are backed by data science.

One test, never changed

Every new model version takes the exact same test with the exact same passing grades. If the score goes up, the model got better. There is no other explanation.

Every roof counts

A roof we can't measure counts against us. A roof we measure badly counts against us. Nothing gets quietly removed to make the numbers look better.

Graded against people

The right answers come from reports measured and certified by human experts. The AI's job is to match what a highly trained person would produce.

Published every release

The same report card comes out with every model release, good news or bad. You can watch each line improve over time, or hold us to it when it doesn't.

Common questions

What does order-ready actually mean?

It means the report is accurate enough to order materials from. The roof size, every edge length, and the steepness all landed close enough to the human-certified answer that a contractor could buy shingles, drip edge, and ridge cap without paying for a legacy report first.

What is the difference between an AI Instant Report and a human certified report?

An Instant Measurement Report is generated by our AI in 15 seconds, about 50x cheaper than a legacy report. A Human Certified Measurement Report is that same measurement checked and certified by a human expert: $10 flat, back in about an hour, and highly accurate every time.

What do you mean by legacy reports?

The measurement reports contractors have ordered for decades. Someone traces the roof from imagery by hand, you pay per report, and it takes hours or days to land. If you have ever bought a roof measurement report, that is what we mean.

Does the report card cover both report types?

No. The card and the three headline numbers grade our AI Instant Reports, because you should see exactly how often they are right. A Human Certified Report is checked line by line by a person before it reaches you, so it is highly accurate every time and has no percentage to publish.

How do you test the AI?

We compare the AI's measurements against roofs that professional estimators measured and certified by hand. Every new model version takes the same test with the same passing grades, so when the score goes up, the model genuinely got better.

What happens when the AI gets a roof wrong?

It counts. Misses show up in the Bust Rate, and roofs we can't measure in the first place show up in Coverage. We publish those numbers next to the good ones because an accuracy claim that hides its failures isn't worth much.

How do I know when to trust an AI Instant Report?

Every AI Instant Report comes with a confidence score, and so does each measurement inside it: roof size, edges, steepness, ridges, valleys, and so on. A high score means you can order materials straight from the report. If any line scores low, that is your sign to double check it, and a $10 Human Certified Report is the easy way to do that.

Does accuracy keep improving?

Yes. Every month brings a new model version, and each one is graded on the exact same test as the last. Waste estimation and roof-to-wall flashing lines are the areas improving fastest right now.

The fastest way to judge a measurement is to compare it to a roof you already know. Run your address and see for yourself.
