๐ก How Much Does a New Roof Cost?
Roofing cost is calculated per square (100 sq ft of roof area). Roof area is larger than floor area due to pitch โ a 6/12 pitch adds 12% to flat area. Common costs per square installed: 3-tab shingles: $350. Architectural shingles: $500. Standing seam metal: $900. Clay tile: $1,300.
Total project cost includes tear-off ($100โ$150/square), underlayment, flashing, ridge caps, and labor. Steep roofs (8/12+), complex geometry (dormers, valleys), and multi-story homes cost 20โ50% more due to additional safety equipment and slower work pace.
30ร24 ft house, 6/12 pitch: 806 sq ft roof area (8.06 squares). Architectural shingles: $2,015 material + $2,015 labor + $1,008 tear-off = $5,038.
