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
| Pitch | Bundles for 1,000 sq ft footprint |
|---|---|
| Flat / low slope | 33 bundles |
| 3:12 | 34 bundles |
| 4:12 | 35 bundles |
| 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.
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.
