How Many Shingles for a 2,000 Sq Ft Roof?
Quick Answer
A 2,000 square foot roof requires 20 roofing squares — that is 60 bundles of 3-tab shingles or 80 bundles of architectural shingles before waste factor.
- 20 roofing squares (2,000 ÷ 100)
- 60 bundles of 3-tab shingles (3 per square)
- 80 bundles of architectural shingles (4 per square)
- With 15% waste: order 69 (3-tab) or 92 (architectural) bundles
Formula
One roofing square covers 100 sq ft. Standard shingles come 3 bundles per square; premium types need 4 bundles per square.
Step-by-Step Calculation
- 1
Calculate squares
2,000 ÷ 100 = 20 squares
- 2
Standard bundles
20 × 3 = 60 bundles
- 3
Add 15% waste
60 × 1.15 = 69 bundles

Underlayment rolls
20 squares → 5 rolls of synthetic underlayment

Frequently Asked Questions
How much does a 2,000 sq ft roof replacement cost?
Total installed cost for a 2,000 sq ft roof is $6,800–$13,000 for architectural shingles. This includes tear-off, materials, labor, and disposal. Premium materials or complex roof designs can push costs to $15,000+.
Can I reshingle over existing shingles?
Most building codes allow one layer of reroofing over existing shingles if the deck is in good condition. However, a full tear-off is recommended for better results and to inspect the decking for damage. Two layers is the maximum allowed.
How many nails per shingle?
Standard installation requires 4 nails per shingle (6 in high-wind zones). For 2,000 sq ft, that is approximately 5,300–8,000 nails depending on wind zone requirements.
