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.
Assumptions to Check
Before ordering materials, confirm the dimensions, product coverage, waste factor, and local installation requirements for your project. Manufacturer coverage tables and local code rules can change the final quantity, especially for structural work, exterior projects, and irregular layouts.
