Roof measurement for roofing contractors
Type the address. RoofCalc finds the building, measures the roof and gives you the area, the facet count and a complexity rating, saved to your account. Then check them on the roof before you order.
Free plan: 2 measurements, no card needed to sign up. Choose Contractor when you create your account.
What the measurement API returns
Plan view, not to scale
Squares, pitch, edge lengths, valleys, hips and waste are built for OpenStreetMap results today, and the app does not show all of them yet. The app shows area, facets, complexity and a confidence label.
How it works
Four steps. You do the first and the last; RoofCalc does the middle.
RoofCalc turns it into coordinates and looks for the building there. One address at a time; each successful measurement uses one credit.
Paid plans try Google Solar roof data first, which carries the roof’s slopes and is graded high, medium or low by imagery quality. Every plan falls back to OpenStreetMap building footprints.
By default, Solar results from April-to-October imagery (leaves on the trees) are skipped in favour of the fallback. A footprint has no slope, so on that path pitch comes from the building’s map tag when there is one, otherwise a regional or building-type estimate.
Area in square feet, facet count and complexity, with a confidence label. Edge lengths, pitch and waste are estimates and not all of them are on screen yet.
If no source has the building, you get a no-data message and no credit is used.
The result is saved to your history, and you can save your own job rates in the app today.
Coming soon A report in the format contractors already use*, a waste factor with its reason, and turning a measurement into a priced quote you can send.
Available now
Each of these runs in the app now. Where one is only part-built, the card says what is missing.
Type an address and get the roof area in square feet, a facet count and a complexity rating, saved to your account.
Not yet: Squares and pitch are calculated but not on the result screen yet. If no source has the building, you get a "no building data" message; drawing the outline by hand is not built yet.
Paid plans try Google Solar building data (sloped roof segments and pitch) first. Every plan falls back to OpenStreetMap building footprints.
Not yet: A LiDAR source is in the code but not part of any plan yet. Footprint estimation and manual tracing tiers are not built.
Every measurement comes back with the data source that produced it, a confidence score, and why better sources were skipped for that address.
Not yet: The app shows a two-level label; the score, source name and skipped sources are in the API response but not on screen yet.
Save your price per square foot, tear-off per layer, decking per sheet, disposal fee and margin on your account.
Not yet: Applying your rates to a measurement to build a quote is not connected in the app yet, and quotes cannot be saved or sent. Saving rates may not work yet in Safari or other browsers that block third-party cookies.
Every measurement you run is saved with its address, area, confidence and data source, and listed in the app.
Not yet: The detail view for a saved measurement is not wired to your data yet.

On the way
These are planned or part-built. None of them is part of what you get today.
Re-tracing from imagery is not built yet.
Not on every data source yet, the app does not show all of it correctly, and PDF export and sharing are not built.
The app does not show the waste percentage, its reason or the take-off correctly yet.
Corrections are not stored between sessions and in-app upload is not connected yet.
The form is live at /homeowner-intake but its field validation needs a fix before we point homeowners at it.
The portal screens show sample data and weather alerts have no data source yet.
No invites, seats or shared workspace yet.
No customer-facing admin screen yet.
Planned for Enterprise.
Who it's for
The app has a side for each. Only one of them is ready.
Measure a roof before the site visit, check where the numbers came from, and keep every job on file.
The homeowner side of the app is still being built. Its screens show sample data today, so we are not asking homeowners to sign up yet. We will switch these on here when they work with your real roof.
