How this calculator works
Add splices, corners, and waste based on actual board lengths.
For best results, measure actual jobsite dimensions, use supplier-specific coverage numbers, and choose a waste factor that matches layout complexity and field conditions.
Real-world estimating notes
Roofing estimates should account for slope, starter, ridge, hips, valleys, waste, and manufacturer coverage. Simple area math is only the first pass.
Before ordering
- Add accessories outside the basic surface area.
- Use roof complexity to choose waste percentage.
- Verify pitch and panel or bundle coverage.
