What you can count on

Questions

Which areas are covered?

Roof reports: the United States and Canada, where public lidar elevation data exists. Storm history: United States addresses, for the last 10 years. In Canada the storm history lists hail reports 2005–2024 only.

What is it measured from, and how accurate is it?

Software measures the roof from public aerial lidar elevation data: USGS 3DEP in the United States, Natural Resources Canada in Canada. Nobody visits the property. Every figure is an estimate, and the report prints the date the elevation data was captured. Verify on site before you order materials.

What if my address cannot be measured?

We tell you why and nothing is charged. Not every address has usable data.

What files do I get?

Roof report: PDF, CSV, JSON, XML and DXF. Storm history: PDF, CSV and JSON. The report also opens in your browser, and we email you the link.

How do I pay?

Through Stripe Checkout: by card, or with Apple Pay or Google Pay where your device supports them. Your card details go to Stripe and never reach our servers. One payment per report, with no account and no subscription.

Can I get a refund?

Yes, in the cases the Refund Policy sets out. For example, a roof report that is materially wrong when you check it on site is refunded in full if you write to us within 30 days of buying it.
