Materials for a 2,400 sq ft roof (6/12)
- Shingles: 97 bundles for a gable roof, 102 for a hip roof.
- Underlayment: 4 rolls of synthetic underlayment (10 squares each) for gable, 4 for hip.
- Ridge cap: about 59 ft of ridge on a gable roof (3 bundles at ~25 ft each); a hip roof has about 141 ft of ridge and hips (6 bundles).
How it is calculated
(59 + 2) ft × (41 + 2) ft = 2,623 sq ft with overhangs
2,623 × √(1 + (6 ÷ 12)²) = 2,623 × 1.118 = 2,933 sq ft of roof
2,933 ÷ 100 × 1.1 = 32.3 squares (gable) · × 1.15 = 33.7 (hip)
32.3 squares × 3 = 97 bundles
Tips for a 2,400 sq ft house
- With 32+ squares, ask for a 30-yard dumpster and get quotes on a per-square basis – larger jobs often earn a lower rate.
- Two-story homes: a 2,400 sq ft two-story house has only about 1,200 sq ft of footprint, so its roof is closer to 16.4 squares (6/12 gable) – not 32.3. Measure the footprint, not the living area.
- Garages, porches and dormers add squares that are not counted in living area – measure them separately.
