About

RoofCalc is built by Harmony AI Technologies

Harmony AI Technologies, founded by Luiz Ribeiro, builds and runs RoofCalc: roof measurements from an address, for roofing contractors.

Why roofing

Every quote starts with a measurement

Before you can price a roof you need its size and pitch. That usually means a ladder and a tape, or ordering a report, paying for it and waiting hours for it to come back. For a job you might not even win, that is a lot of time and money up front.

So we start from the address

RoofCalc measures the roof from building data it can look up, and keeps the data source and a confidence score with each result. You get a first number from the office, then decide whether the job is worth the drive. Applying your saved rates to build a quote is coming soon.

We tell you what is not built

Every feature on this site was checked against the code before it went up. Anything that is not built yet is marked Coming soon. We do not publish accuracy numbers we have not measured, and there are no made-up reviews here.

Where it stands

Live today and coming soon

Live today

  • Measure a roof from an address. Type an address and get the roof area in square feet, a facet count and a complexity rating, saved to your account.
  • Google Solar roof data, OpenStreetMap fallback. Paid plans try Google Solar building data (sloped roof segments and pitch) first. Every plan falls back to OpenStreetMap building footprints.
  • Confidence score and data source with every result. Every measurement comes back with the data source that produced it, a confidence score, and why better sources were skipped for that address.
  • Save your job rates. Save your price per square foot, tear-off per layer, decking per sheet, disposal fee and margin on your account.
  • Measurement history. Every measurement you run is saved with its address, area, confidence and data source, and listed in the app.
  • Dashboard and measurement credits. See your measurements, activity and remaining credits on one dashboard.

Coming soon

Coming soon
  • Automatic cross-check on footprint measurements. OpenStreetMap measurements checked for common footprint problems and, when flagged, re-traced from imagery.
  • Reports in the format contractors already use. Results laid out the way roofing measurement reports usually are: total squares, predominant pitch, facets, ridge, eave and rake lengths, and valley and hip counts.
  • Waste factor with the reason. A recommended waste percentage for each measurement, with the reason, based on roof complexity, pitch and number of facets.
  • Calibration from your past reports. Upload measurement reports you already have so RoofCalc can learn a correction for your area.
  • Homeowner estimate request. Homeowners can request a roof estimate with their address and contact details, with a regional price range preview.
  • Homeowner portal: roof health, maintenance, weather alerts. A home for the roof: a health score, a seasonal maintenance checklist and local weather alerts.
  • Team workspaces. One workspace for your crew with shared measurements and per-seat credits.
  • Admin controls for your company. Manage users, roles and usage for your company account.
  • White-label reports and integrations. Reports under your company brand, and connections to the tools you already use.
