Quick Summary & Key Answer

To calculate roof shingle bundles: multiply ground footprint by your pitch multiplier, add 10-15% for waste, divide by 100 to get roofing squares, and multiply by 3 bundles per square. For example, a 2,000 sq ft footprint at 6:12 pitch equals 22.4 squares, requiring 25 squares with 10% waste, or 75 total shingle bundles.

1 Roofing Square = 100 square feet.
3 Bundles of architectural shingles = 1 Square.
Standard hip and valley roofs require 15% waste allowance.

Total Roofing Squares (100 sq ft): 25 squares
Actual Roof Surface Area: 2240 sq ft
Area Including Waste: 2464 sq ft
Nails Required (4 nails per shingle): 8,000 nails

Note: Standard architectural shingles are packaged at 3 bundles per square (100 sq ft of coverage).

Estimating Asphalt Shingle Bundles

Order starter shingles and ridge caps separately; cutting 3-tab shingles for caps reduces warranties on architectural roofs.
