How Many Bundles of Shingles for 4,000 sq ft?
4,000 sq ft of roof surface is 40 roofing squares. With 10% waste and standard 3-bundle-per-square shingles you need 132 bundles. If 4,000 sq ft is the house footprint rather than the roof, multiply by the pitch factor first: at a 6/12 pitch that becomes 148 bundles.

If 4,000 sq ft is the house footprint
Shingles cover the sloped roof, not the floor plan. Multiply the footprint (including overhangs) by the pitch factor to get roof surface:
| Pitch | Roof surface | Squares (+10%) | Bundles |
|---|---|---|---|
| 3/12 | 4,123 sq ft | 45.4 | 137 |
| 4/12 | 4,216 sq ft | 46.4 | 140 |
| 5/12 | 4,333 sq ft | 47.7 | 143 |
| 6/12 | 4,472 sq ft | 49.2 | 148 |
| 7/12 | 4,631 sq ft | 50.9 | 153 |
| 8/12 | 4,807 sq ft | 52.9 | 159 |
| 9/12 | 5,000 sq ft | 55 | 165 |
| 10/12 | 5,207 sq ft | 57.3 | 172 |
| 12/12 | 5,657 sq ft | 62.2 | 187 |
3 bundles per square, 10% waste. Don't know your pitch? Measure it with the Pitch Gauge.

Frequently asked questions
How many bundles of shingles do I need for 4,000 sq ft?
For 4,000 sq ft of roof surface you need 132 bundles of standard shingles (3 bundles per square) including 10% waste, or 138 bundles with 15% waste for a roof with hips and valleys. Heavier shingles packed 4 bundles per square need 176 bundles.
How many squares is 4,000 sq ft?
A roofing square is 100 sq ft, so 4,000 sq ft is 40 squares, or 44 squares once you add 10% for waste.
Is 4,000 sq ft the house size or the roof size?
Shingles are ordered by roof surface, which is larger than the house footprint because of the slope and overhangs. If 4,000 sq ft is your footprint, multiply it by your pitch factor: at 6/12 the roof is 4,472 sq ft and needs 148 bundles.
How much do shingles for 4,000 sq ft cost?
At typical material prices, shingles for 4,000 sq ft of roof (with 10% waste) cost about $3,520–$5,280 for 3-tab shingles, $4,400–$7,040 for architectural shingles, $7,040–$11,000 for premium shingles. That is materials only; installation usually costs more than the shingles.
