How many bundles of shingles for 1,000 sq ft?
Quick Answer
A house with 1,000 square feet of flat footprint and a 4:12 pitch has an actual roof area of 1,054 sq ft. Adding 10% waste = 1,159 sq ft ÷ 100 = 11.6 squares × 3 bundles = 35 bundles. For a steeper 6:12 pitch: 38 bundles. Always verify by measuring the actual roof, not the floor plan.
Quick Reference Table

| 6:12 | 38 bundles |
| 8:12 | 40 bundles |
| 12:12 | 47 bundles |
How to Calculate It Yourself
- 1
Start with flat footprint: 1,000 sq ft.
- 2
Apply pitch multiplier (4:12 = ×1.054): 1,054 sq ft actual area.
- 3
Add 10% waste: 1,054 × 1.10 = 1,159 sq ft.
- 4
Divide by 33 (sq ft per bundle): 1,159 ÷ 33 = 35.1 → buy 36 bundles.
Pro Tip
Don't forget ridge cap and starter strips — these are sold separately. Measure your ridge length and divide by 35 (linear feet per bundle of ridge cap). A simple gable on a 1,000 sq ft house has about a 32-foot ridge, needing 1 bundle of ridge cap.
