Roofing Cost Calculator
Use this free Roofing Cost Calculator to estimate roof replacement cost based on roof area, material type, labor level, and waste percentage.
How This Roofing Cost Calculator Works
This calculator estimates roofing cost by multiplying your adjusted roof area by an estimated cost per square foot. The result is only a rough estimate and may vary based on location, roof pitch, labor rates, material quality, tear-off, permits, and contractor pricing.
Roofing Cost Formula
Adjusted Area = Roof Area × (1 + Waste %)
Estimated Cost = Adjusted Area × Material Cost × Labor Difficulty
Example Calculation
For a 2,000 sq ft asphalt shingle roof with 10% waste:
- Adjusted Area: 2,200 sq ft
- Estimated Cost: 2,200 × $4.50
- Approximate Cost: $9,900
Average Roofing 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 |
