Roofing Calculators

Footprint and pitch to approximate squares or packs for planning.

1 calculator

Estimate roof area, squares, and shingle bundles from a plan footprint and pitch.

Turn a building footprint and pitch into squares, bundles, and a planning waste allowance — without treating the result as a roofer's takeoff.

Why calculators add waste, typical ranges by material, and how to avoid both short orders and expensive overbuying.
