Other materials
- Synthetic underlayment: about 4 rolls at 10 squares per roll (more on low slopes that need double coverage).
- Starter strip and ridge cap: sold separately; their quantity depends on eave and ridge length.
- Roofing nails: typically 4 per shingle, or 6 in high-wind areas — follow the shingle wrapper.
Footprint is not living area. A two-story 6,000 sq ft home could have a 3,000 sq ft footprint. Include an attached garage and covered porches if they share the roof.
The math (6/12 pitch)
3,000 sq ft × 1.118 = 3,354 sq ft of roof
÷ 100 × 1.10 = 36.89 squares
× 3 bundles/square = 111 bundles (rounded up)
