Roof Replacement Cost Calculator
Use this free Roof Replacement Cost Calculator to estimate the cost of replacing a roof based on roof area, material type, tear-off, labor difficulty, and waste percentage.
How This Roof Replacement Cost Calculator Works
This calculator estimates roof replacement cost by adding roofing material cost, tear-off cost, waste, and labor difficulty. The result is a rough estimate and may vary based on location, roof pitch, permits, contractor pricing, and roof condition.
Roof Replacement Cost Formula
Adjusted Area = Roof Area × (1 + Waste %)
Material Cost = Adjusted Area × Material Cost Per Sq Ft
Tear-Off Cost = Roof Area × Tear-Off Cost Per Sq Ft
Total Estimate = (Material Cost × Labor Difficulty) + Tear-Off Cost
Example Calculation
For a 2,000 sq ft asphalt shingle roof with 10% waste and standard tear-off:
- Adjusted Area: 2,200 sq ft
- Material Cost: 2,200 × $4.50 = $9,900
- Tear-Off Cost: 2,000 × $1.50 = $3,000
- Estimated Average Cost: $12,900
Average Roof Replacement Cost by Material
| Material | Estimated Cost / sq ft |
|---|---|
| Asphalt Shingles | $3.50 - $6.00 |
| Metal Roofing | $7.00 - $12.00 |
| Tile Roofing | $10.00 - $18.00 |
| Wood Shingles | $6.00 - $10.00 |
| Premium Roofing | $12.00 - $20.00+ |
