Step-by-step
- Material + install = 25 × $475 × 1 = $11,875.
- Tear-off = 25 × 100 × $1 = $2,500.
- Total = $14,375.
How to use this calculator
- Use roofing-square-count to convert footprint to squares.
- Pick material.
- Set tear-off layers (most homes have 1-2).
- Set pitch — measure ratio of rise:run over 12 inches.
About this calculator
Roofing is sold by the square (10×10 = 100 ft²). A 2,500 ft² ranch has roughly 28-32 squares depending on pitch. Architectural asphalt is the residential standard at $400-550/sq installed. Metal doubles that but lasts 50+ years. Tile and slate are regional/luxury choices. Tear-off (removing old roofing) typically runs $100/sq per layer; many jurisdictions cap at 2 layers before a complete tear-off is required. Steep pitches add labor surcharge for safety.
Frequently asked
Footprint × pitch multiplier. A 1,500 ft² footprint with 6:12 pitch ≈ 1,500 × 1.118 / 100 = 16.8 squares.
