How Much Does Roofing Cost?
Roofing costs vary widely based on several factors. Understanding these factors helps you make informed decisions about your roofing project.
Factors That Affect Cost
- Roof size: Measured in squares (100 sq ft each)
- Material choice: From affordable asphalt to premium slate
- Roof complexity: Pitch, valleys, dormers, penetrations
- Location: Labor costs vary by region
- Tear-off needs: Removing old roofing adds cost
- Decking repairs: Structural issues increase price
- Accessibility: Hard-to-reach roofs cost more
Average Cost Per Square (100 sq ft)
- Asphalt Shingles: $3,000-$7,000
- Metal Roofing: $7,000-$15,000
- Tile Roofing: $10,000-$20,000
- Slate Roofing: $15,000-$30,000
- Flat Roof (TPO/EPDM): $5,000-$10,000
* Costs include materials and labor. Prices vary by location and project complexity.
Example: A typical 2,000 sq ft roof (20 squares) with asphalt shingles might cost $6,000-$14,000 total, while the same roof with metal might cost $14,000-$30,000. Use the calculator above for a more specific estimate based on your roof dimensions.
