This will first show your building footprint, then allow you to calculate roofing materials.
Calculation Process
Building Detection
We use OpenStreetMap building data overlaid on Google Maps satellite imagery to accurately identify your roof. This gives us a precise footprint area measurement.
Area Calculation
We calculate your true roof area by adjusting the footprint area based on your roof's pitch. Steeper roofs have a larger surface area than the building footprint.
Bundle Calculation
Our bundle-based approach calculates to the nearest bundle instead of the nearest square (100 sq ft), reducing waste and saving you money.
Cost Estimation
We calculate material and installation costs based on the bundle-adjusted area and your selected material. Our estimates account for pitch difficulty, tear-off fees, and contractor margins.
Building Visualization
View your building footprint on a satellite map with accurate measurements of each wall.
