How Many Shingles for a 2,000 Sq Ft Roof?

Bundles, Squares & Waste for an Average Home

A 2,000 sq ft roof at 6/12 pitch covers about 2,236 sq ft of actual sloped surface area (using a 1.118 multiplier). At 3 bundles per square plus 15% waste, that works out to roughly 78 bundles of architectural shingles, or 26 squares total. This article walks through the full calculation including ridge cap, starter strip, drip edge, and underlayment for the same 2,000 sq ft home, with a complete materials list and budget estimate.
