Roof Calculator & Estimator
Measure roof areas, calculate roofing squares, estimate materials, and create professional reports.
Roof Calculator & Estimator helps contractors, roofers, adjusters, and homeowners measure roofs from satellite imagery. Enter an address, trace roof sections, assign pitch, and classify edges such as eaves, rakes, ridges, hips, and valleys to calculate footprint area, true roof area, roofing squares, waste, and material quantities.
Turn roof measurements into practical job estimates with custom material prices, labor rates, tear-off costs, tax settings, markup, discounts, waste percentages, and coverage assumptions. Save customer details, site notes, jobsite photos, photo observations, roof diagrams, and satellite snapshots, then export PDF roof reports or materials lists with Pro.
