Materials for a 2,800 sq ft roof (6/12)

  • Shingles: 111 bundles for a gable roof, 117 for a hip roof.
  • Underlayment: 4 rolls of synthetic underlayment (10 squares each) for gable, 4 for hip.
  • Ridge cap: about 62 ft of ridge on a gable roof (3 bundles at ~25 ft each); a hip roof has about 152 ft of ridge and hips (7 bundles).

How it is calculated

(62 + 2) ft × (45 + 2) ft = 3,008 sq ft with overhangs
3,008 × √(1 + (6 ÷ 12)²) = 3,008 × 1.118 = 3,363 sq ft of roof
3,363 ÷ 100 × 1.1 = 37 squares (gable) · × 1.15 = 38.7 (hip)
37 squares × 3 = 111 bundles

Tips for a 2,800 sq ft house

  • With 37+ 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 2,800 sq ft two-story house has only about 1,400 sq ft of footprint, so its roof is closer to 19.2 squares (6/12 gable) – not 37. Measure the footprint, not the living area.
  • Garages, porches and dormers add squares that are not counted in living area – measure them separately.
