Materials for a 2,500 sq ft roof (6/12)

  • Shingles: 101 bundles for a gable roof, 106 for a hip roof.
  • Underlayment: 4 rolls of synthetic underlayment (10 squares each) for gable, 4 for hip.
  • Ridge cap: about 60 ft of ridge on a gable roof (3 bundles at ~25 ft each); a hip roof has about 144 ft of ridge and hips (6 bundles).

How it is calculated

(60 + 2) ft × (42 + 2) ft = 2,728 sq ft with overhangs
2,728 × √(1 + (6 ÷ 12)²) = 2,728 × 1.118 = 3,050 sq ft of roof
3,050 ÷ 100 × 1.1 = 33.5 squares (gable) · × 1.15 = 35.1 (hip)
33.5 squares × 3 = 101 bundles

Tips for a 2,500 sq ft house

  • With 34+ 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 2,500 sq ft two-story house has only about 1,250 sq ft of footprint, so its roof is closer to 17.3 squares (6/12 gable) – not 33.5. Measure the footprint, not the living area.
  • Garages, porches and dormers add squares that are not counted in living area – measure them separately.
