Roofing Material Estimator
Estimate roofing squares and shingle bundles from roof footprint area, pitch multiplier, waste, and bundle coverage.
Limitations: Does not include ridge cap, starter, underlayment, ice-and-water shield, vents, flashing, or manufacturer-specific starter/ridge bundle counts.
What to do next: Architectural shingles are often sold 3 bundles per square, but verify the wrapper. Valleys, dormers, hips, and cut-heavy roofs often need more waste than simple gable roofs.
Planning estimate only. Final roofing takeoff should be verified from actual roof measurements and the selected shingle product.
