Architectural (dimensional) shingles — 1,500 sq ft step-by-step

Slope factor for 6/12 pitch: √(6² + 12²) / 12 = 1.1180,Actual roof area: 1,500 sq ft (footprint) × 1.1180 = 1677.1 sq ft,Add 10% waste (Simple gable): 1677.1 × 1.10 = 1844.8 sq ft,Roofing squares (1 square = 100 sq ft): 1844.8 ÷ 100 = 18.45 squares,Bundles (3 bundles/square): ⌈18.45 × 3⌉ = 56 bundles,Starter strip (≈ 77 lin ft eave): ⌈77 ÷ 105⌉ = 1 bundle(s),Ridge cap (≈ 19 lin ft ridge): ⌈19 ÷ 30⌉ = 1 bundle(s),Total weight: 18.45 squares × 320 lbs/sq = 5,903 lbs (3.5 psf dead load),Installed cost range: $6,457 – $12,913 (18.4 squares at $350–$700/sq)
