How many square feet does a bundle of shingles cover?
Quick Answer
One bundle of standard asphalt shingles covers approximately 33 square feet of roof area. Three bundles equal one roofing square, which covers 100 square feet. This applies to both 3-tab and architectural (dimensional) shingles — the bundle count is the same, though architectural shingles have fewer but larger pieces per bundle.
Quick Reference Table
| Shingle type | Bundle coverage |
|---|---|
| 3-Tab asphalt | 33 sq ft per bundle |
| Architectural (dimensional) | 33 sq ft per bundle |
| Impact-resistant | 32–33 sq ft per bundle |
| Hip & ridge caps | ~20 lin ft per bundle |
| 1 roofing square | 100 sq ft = 3 bundles |
How to Calculate It Yourself
- 1
Measure your roof footprint: length × width for each section.
- 2
Multiply by the pitch multiplier (e.g., 6/12 pitch = ×1.118) to get actual roof area.
- 3
Divide by 100 to get roofing squares.
- 4
Multiply by 3 to get bundles. Add 10–15% for waste and hip/ridge cuts.
- 5
Example: 1,500 sq ft roof → 15 squares → 45 bundles + 10% = 50 bundles.
Pro Tip
Always order an extra 10% for waste, especially for cut areas around valleys, hips, and ridges. Leftover shingles are useful for future repairs — keep them if they're undamaged.
