Roofing material takeoff calculator

For roofing pros: enter the roof area and a waste factor to get a fast material takeoff — squares, shingle bundles, underlayment rolls, and nails — as a starting bill of materials.

What a takeoff covers

This gives the core field materials from your roof area: squares (with waste), shingle bundles (3 per square), synthetic underlayment rolls (10 squares each), and coil nails. Add starter strip, ridge cap, drip edge, and ice-and-water shield based on your eave, rake, hip, and valley measurements. For pricing, pair it with the markup & margin calculator.

Cost ranges reflect 2026 U.S. installed prices (BLS producer/labor data, Remodeling Cost vs. Value, and manufacturer pricing). Your real price depends on your roof, region, and pro — see the full cost guide.
