The Complete Roofing Materials List
Every roof replacement needs more than just shingles. Here's what a typical asphalt shingle roof job includes:
- Shingles: 3 bundles per square (100 sq ft), plus waste
- Synthetic underlayment: 1 roll covers roughly 10 squares
- Ice and water shield: Covers eaves, valleys, penetrations (1 roll covers ~200 linear feet of eave)
- Roofing nails: ~320 nails per square for standard 4-nail pattern
- Drip edge: Linear feet of eave + rake
- Starter strip: 1 bundle per ~105 linear feet of eave and rake
- Ridge cap: 1 bundle per ~30 linear feet of ridge
Material Coverage Notes
Coverage varies by manufacturer. Always check the wrapper before ordering. Architectural shingles are typically 3 bundles per square, but some premium lines are 4 bundles per square. Ice and water shield should cover at least 6 feet up from the eave per building code in most cold-climate regions.
