The cost of roof replacement in the U.S. varies widely based on several factors. Here are the five key factors that impact pricing:
1. Roof Size & Pitch
Size: Measured in squares (100 sq. ft. per square), larger roofs cost more.
Pitch (Slope): Steeper roofs require more labor, safety equipment, and sometimes specialized materials, increasing costs.
2. Material Choice
Asphalt Shingles: Most affordable ($3–$7 per sq. ft.).
Metal Roofing: Mid-range ($7–$15 per sq. ft.), durable but pricier.
Tile (Clay/Concrete): High-end ($10–$25 per sq. ft.), heavy and labor-intensive.
Slate: Premium ($15–$30+ per sq. ft.), long-lasting but expensive.
3. Labor Costs & Location
Labor rates vary by region (e.g., higher in coastal cities like NYC or SF).
Permits & local building codes can add $500–$2,000+ to the total cost.
4. Roof Complexity
Features like skylights, chimneys, or multiple valleys increase labor time.
Tear-off costs: Removing old roofing adds $1–$5 per sq. ft. (more for multiple layers).
5. Underlayment & Additional Repairs
Damaged decking (plywood/OSB) adds $3–$5 per sq. ft. for replacement.
High-quality underlayment (synthetic vs. felt) affects durability and cost.
Bonus: Other Influences
Seasonal Demand: Prices rise in peak seasons (spring/summer).
Warranty: Longer warranties (30–50 years) often mean higher upfront costs.
Estimated Total Cost Range:
Basic asphalt shingle roof: $5,000–$12,000 (1,500 sq. ft. home).
Premium materials (metal, tile, slate): $15,000–$50,000+.
