How we got these numbers
This page uses the method in our roof replacement cost guide for the roof's area: the footprint times the pitch factor. It divides that by 100 square feet for the squares, multiplies by the bundles a square takes, adds the waste allowance and rounds up to a whole bundle. The 2% to 10% waste band is the one in our bundles guide.
The pitch factors are geometry, calculated for this page: the square root of one plus the pitch squared. They assume every plane of the roof has the same pitch; dormers, valleys and mixed pitches add surface.
- Low (4 in 12): × 1.054
- Medium (6 in 12): × 1.118
- Steep (9 in 12): × 1.25
- Very steep (12 in 12): × 1.414
The bundles a square takes, each from its guide:
- 3-tab or standard laminated: 3 bundles a square, from the guide.
- Heavier laminated: 4 bundles a square, from the guide.
- Large-format premium: 5 bundles a square, from the guide.
- Thick luxury: 6 bundles a square, from the guide.
The table counts every roof at a medium pitch. A bundle count on an estimate also covers the ridge cap, starter and other products only if the line says so. Bundle counts are for a square of 100 square feet and are estimates; the maker's data sheet for the line on your estimate is the one that counts.
