Other materials
- Synthetic underlayment: about 2 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 2,400 sq ft home could have a 1,200 sq ft footprint. Include an attached garage and covered porches if they share the roof.
The math (6/12 pitch)

÷ 100 × 1.10 = 14.76 squares
× 3 bundles/square = 45 bundles (rounded up)
