How many bundles of shingles for a 10×10 shed?
Quick Answer
A 10×10 shed with a standard gable roof at 4:12 pitch has a roof area of about 105 sq ft (2 sides), plus waste — requiring about 4 bundles of shingles. At a steeper 6:12 pitch: 5 bundles. Add 1 bundle for ridge cap and starter strip. Total: 5–7 bundles for most 10×10 sheds.
Quick Reference Table
| Roof pitch | Bundles needed (10×10 shed) |
|---|---|
| 3:12 gable | 4 bundles field + 1 starter = 5 total |
| 4:12 gable | 4–5 bundles + 1 starter = 5–6 total |
| 6:12 gable | 5–6 bundles + 1 starter = 6–7 total |
| 8:12 gable | 6–7 bundles + 1 starter = 7–8 total |
| Hip roof 4:12 | 6–8 bundles total |
How to Calculate It Yourself
- 1
Calculate one roof face: 10 ft wide × rake length. For 4:12 pitch, rake = √(5² + 10²) = 11.18 ft. One face = 10 × 11.18 = 111.8 sq ft.
- 2
Multiply by 2 faces (gable): 223.6 sq ft total.
- 3
Add 15% waste for a small roof (more cuts, more waste %): 223.6 × 1.15 = 257 sq ft.
- 4
Divide by 33 (sq ft per bundle): 257 ÷ 33 = 7.8 → buy 8 bundles plus 1 ridge/starter bundle.
Pro Tip
Small roofs like sheds have a higher waste percentage than large roofs because the ratio of edges to field area is higher. Budget 15% waste instead of 10% for any roof under 500 sq ft.
