🏠 Understanding Roofing Squares and Bundles

When planning a roofing project, understanding the relationship between squares and bundles is essential for accurate material estimation. Roofers use "squares" as the standard unit of measurement, while shingles are sold in bundles.

Key Measurements

  • 1 Roofing Square = 100 square feet of roof area
  • 1 Bundle covers ~33.3 sq ft (so 3 bundles = 1 square for standard shingles)
  • 1 Bundle contains ~29 shingles (standard 12" × 36" three-tab)
  • Add 10-20% waste factor for cutting, overlaps, and mistakes

Shingle Types Compared

3-Tab Shingles (3 bundles/square)

Basic, flat appearance. Most affordable option at $25-$35/bundle. Lifespan of 15-20 years. Best for budget-conscious projects.

Architectural Shingles (4 bundles/square)

Dimensional, textured look. Mid-range pricing at $30-$45/bundle. Lifespan of 25-30 years. Most popular choice for homes.

Luxury Shingles (4-5 bundles/square)

Premium, slate-like appearance. Higher cost at $45-$60/bundle. Lifespan of 30+ years. Best curb appeal and warranty.

📊 Did You Know?

Average US roof = 17 squares (1,700 sq ft)

That's about 51-68 bundles depending on shingle type

Architectural shingles are now 80% of the market

⚠️ Common Mistakes

  • Using house sq ft instead of roof sq ft
  • Forgetting the 10-20% waste factor
  • Not accounting for valleys/dormers
  • Mixing shingle brands (color varies)
