About this calculator

This calculator converts a roof's area into roofing squares — the trade's standard unit, where one square equals 100 square feet — and then estimates how many shingle bundles that requires, typically three bundles per square for standard architectural shingles.

Roofing contractors and estimators use squares to quote jobs and order materials in the units suppliers actually sell them in, and homeowners use it to sanity-check a quote or plan a DIY reroofing project. Enter the roof's dimensions or total area to get the square count and bundle estimate.
