What Affects the Cost of Roof Replacement?
➤ 1.1 Size of the Roof: Why Square Footage Matters
Roofers calculate pricing using “squares”—each square equals 100 square feet. The cost per square foot of roof replacement typically ranges from $3 to $12, depending on material and labor.
A small 1,000 sq ft roof (10 squares) might cost $3,000–$12,000. Larger homes or more complex roofs increase costs accordingly. Always check the average cost of roof replacement per square to get a general idea.
➤ 1.2 Material Type: Which Roof Costs More?
Material is the biggest factor in your final price. Here’s a quick look:
- Shingle Roofs: Common and affordable. Cost of shingle roof replacement ranges from $4–$8 per sq ft.
- Metal Roofs: Durable but pricey. Average cost of metal roof replacement can be $8–$14 per sq ft.
- Flat Roofs: Used on garages or additions. Lower slope = cheaper labor.
- Mobile Homes & RVs: Unique materials and labor challenges change the cost of replacing roof on mobile home or cost of RV roof replacement.
➤ 1.3 Roof Pitch and Design: How It Changes Labor Costs
Steep or complex roofs take more time and safety gear, driving up labor. A basic flat or low-slope roof is cheaper to install. More valleys, chimneys, or dormers? Expect higher labor costs.

The cost of roof replacement in NJ tends to be 10–20% higher than the national average due to:
