How Much Does a New Roof Cost?
Replacing a roof is one of the most significant investments a homeowner will make. On average, most homeowners spend between $7,000 and $15,000 for a full roof replacement, though premium materials like metal or slate can push costs well above $30,000.
Key Factors Affecting Your Quote
- Roof Size (Square Footage): Roofing contractors charge by the "square." One roofing square equals 100 square feet.
- Pitch (Slope): Steeper roofs require more safety equipment, specialized harnesses, and more time to navigate, increasing labor costs.
- Material Choice: Asphalt shingles are the most budget-friendly, while metal and tile offer greater longevity at a higher price point.
- Removal of Old Layers: If your current roof has multiple layers of shingles, the labor and disposal fees for "tearing off" the old material will increase.
Roofing Material Price Comparison
| Material | Avg. Lifespan | Cost Level |
|---|---|---|
| Asphalt Shingles | 15-25 Years | $ |
| Metal Roofing | 40-70 Years | $$$ |
| Clay or Concrete Tile | 50-100 Years | $$$$ |
Calculation Example
If you have a 2,000 sq. ft. home with a standard slope (1.15 multiplier), your actual roof surface area is roughly 2,300 sq. ft. If you choose architectural shingles ($6.50/sqft including materials) and need a single layer removed ($1.50/sqft), plus standard labor ($3.50/sqft), your calculation would look like this:
2,300 sq. ft. x ($6.50 + $1.50 + $3.50) = $26,450
