Understanding Shingle Bundles
Bundle Coverage
Standard 3-tab shingles: 3 bundles = 1 square (100 sq ft)
Architectural shingles: 3 bundles = 1 square (100 sq ft)
Ridge cap shingles: 1 bundle ≈ 35 linear feet
Why Waste Factor Matters
Waste factor accounts for cuts, overlaps, damaged pieces, and future repairs. Complex roofs with many valleys, dormers, or angles require higher waste factors.
