Roof squares for a 1,400 sq ft house by pitch
Assumes a rectangular footprint about 44 × 32 ft (length = 1.4 × width) with 12-inch overhangs.
| Pitch | Multiplier | Roof area | Squares (gable, +10%) | Squares (hip, +15%) | Bundles (gable) |
|---|---|---|---|---|---|
| 4/12 | 1.054 | 1,649 sq ft | 18.1 | 19 | 55 |
| 6/12 | 1.118 | 1,749 sq ft | 19.2 | 20.1 | 58 |
| 8/12 | 1.202 | 1,880 sq ft | 20.7 | 21.6 | 63 |

Cost to replace the roof on a 1,400 sq ft house
| Roof type (6/12) | Squares | Asphalt shingles | Metal roofing |
|---|---|---|---|
| Gable | 19.2 | $6,732–$10,579 | $15,388–$26,929 |

Materials for a 1,400 sq ft roof (6/12)
- Shingles: 58 bundles for a gable roof, 61 for a hip roof.
- Underlayment: 2 rolls of synthetic underlayment (10 squares each) for gable, 3 for hip.
- Ridge cap: about 44 ft of ridge on a gable roof (2 bundles at ~25 ft each); a hip roof has about 108 ft of ridge and hips (5 bundles).
How it is calculated
(44 + 2) ft × (32 + 2) ft = 1,564 sq ft with overhangs
1,564 × √(1 + (6 ÷ 12)²) = 1,564 × 1.118 = 1,749 sq ft of roof
1,749 ÷ 100 × 1.1 = 19.2 squares (gable) · × 1.15 = 20.1 (hip)
19.2 squares × 3 = 58 bundles
Tips for a 1,400 sq ft house
- At under 20 squares, a small roof often hits the roofer's minimum charge, so the per-square price can land at the high end of the range.
- Two-story homes: a 1,400 sq ft two-story house has only about 700 sq ft of footprint, so its roof is closer to 10 squares (6/12 gable) – not 19.2. Measure the footprint, not the living area.
- Garages, porches and dormers add squares that are not counted in living area – measure them separately.
