How Many Shingles for a 1,000 Sq Ft Roof?
Quick Answer
A 1,000 square foot roof is 10 roofing squares — that is 30 bundles of 3-tab shingles or 40 bundles of architectural shingles before waste. With 15% waste, order 35 (3-tab) or 46 (architectural) bundles.
- 10 roofing squares (1,000 ÷ 100)
- 30 bundles of 3-tab (3 per square)
- 40 bundles of architectural (4 per square)
- With 15% waste: 35 (3-tab) or 46 (architectural) bundles
Formula
One roofing square covers 100 sq ft. Standard 3-tab shingles come 3 bundles per square; architectural shingles need 4 bundles per square. Add 15% for waste, cuts, and starter courses.
Step-by-Step Calculation
- 1
Calculate squares
1,000 ÷ 100 = 10 squares
- 2
Standard bundles
10 × 3 = 30 bundles
- 3
Add 15% waste
30 × 1.15 = 34.5 → 35 bundles

Underlayment rolls
10 squares → 3 rolls of synthetic underlayment
