Roof square estimate
Roof squares calculator that shows footprint, pitch-adjusted area, and waste
Use roof planes and pitch to estimate squares, then translate the result into bundles, rolls, accessories, and cost assumptions.
Main workflow
Roofing material workspace
Estimate pitched roof area, squares, bundles, underlayment, accessories, and cost as a planning estimate.
Planning estimate only. Verify final dimensions, site conditions, material defects, and supplier requirements before ordering or cutting.

Why planners use it

Square calculation notes
Roofing squares are convenient for shingles, but manufacturer coverage and local waste rules can vary. Review product data before ordering.
