Materials for a 1,000 sq ft roof (6/12)

  • Shingles: 42 bundles for a gable roof, 44 for a hip roof.
  • Underlayment: 2 rolls of synthetic underlayment (10 squares each) for gable, 2 for hip.
  • Ridge cap: about 37 ft of ridge on a gable roof (2 bundles at ~25 ft each); a hip roof has about 91 ft of ridge and hips (4 bundles).

How it is calculated

(37 + 2) ft × (27 + 2) ft = 1,131 sq ft with overhangs
1,131 × √(1 + (6 ÷ 12)²) = 1,131 × 1.118 = 1,264 sq ft of roof
1,264 ÷ 100 × 1.1 = 13.9 squares (gable) · × 1.15 = 14.5 (hip)
13.9 squares × 3 = 42 bundles

Tips for a 1,000 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 1,000 sq ft two-story house has only about 500 sq ft of footprint, so its roof is closer to 7.2 squares (6/12 gable) – not 13.9. Measure the footprint, not the living area.
  • Garages, porches and dormers add squares that are not counted in living area – measure them separately.
