Materials for a 1,600 sq ft roof (6/12)

  • Shingles: 66 bundles for a gable roof, 69 for a hip roof.
  • Underlayment: 3 rolls of synthetic underlayment (10 squares each) for gable, 3 for hip.
  • Ridge cap: about 47 ft of ridge on a gable roof (2 bundles at ~25 ft each); a hip roof has about 115 ft of ridge and hips (5 bundles).

How it is calculated

(47 + 2) ft × (34 + 2) ft = 1,764 sq ft with overhangs
1,764 × √(1 + (6 ÷ 12)²) = 1,764 × 1.118 = 1,972 sq ft of roof
1,972 ÷ 100 × 1.1 = 21.7 squares (gable) · × 1.15 = 22.7 (hip)
21.7 squares × 3 = 66 bundles

Tips for a 1,600 sq ft house

  • A roof this size is usually a one-day tear-off for a 4–5 person crew, and most dumpsters (20 yard) handle the 22 squares of old shingles.
  • Two-story homes: a 1,600 sq ft two-story house has only about 800 sq ft of footprint, so its roof is closer to 11.2 squares (6/12 gable) – not 21.7. Measure the footprint, not the living area.
  • Garages, porches and dormers add squares that are not counted in living area – measure them separately.
