Free manual-input planning calculator
Free Roofing Material Waste Calculator
Calculate additional material square footage from measured sloped roof area and your chosen waste allowance. Roof geometry and installation details must be evaluated separately.
What's included—and what's not
This is a preliminary manual-input calculation, not a blueprint takeoff or construction bid. Roofing results do not cover ridge and starter products, flashing, underlayment, penetrations, labor or supplier-specific packaging. Excavation results exclude soil classification, overburden restrictions, haul-distance costs, weights, legal truck limits, disposal fees and actual fleet dispatch. Verify site conditions and supplier specifications.
