Replacing a roof typically costs between $375 and $850 per square, where one "square" equals 100 square feet of roofing material. This pricing range covers most standard roofing projects in the U.S. and aligns with the national average total replacement cost, which falls between $5,867 and $13,213, depending on the home’s size, roof pitch, material, and labor.
A roofing square is a standard measurement used by contractors and roofing professionals. 1 roofing square = 100 square feet of roof surface area. So, if your roof is 2,000 square feet, you’re dealing with 20 squares.
| Material Type | Cost Per Square | Example (20 Squares / 2,000 sq ft) |
|---|---|---|
| Asphalt Shingles | $375 – $550 | $7,500 – $11,000 |
| Architectural Shingles | $450 – $700 | $9,000 – $14,000 |
| Metal Roofing | $800 – $1,200 | $16,000 – $24,000 |
| Wood Shakes/Shingles | $700 – $1,000 | $14,000 – $20,000 |
| Clay or Concrete Tiles | $900 – $1,800+ | $18,000 – $36,000+ |
| Slate Roofing | $1,200 – $2,500+ | $24,000 – $50,000+ |
Note: Costs include both material and labor.
Roof Size & Complexity
Larger roofs require more materials and labor, and complex designs with dormers or multiple slopes can increase the number of squares needed.
Roof Pitch (Steepness)
Steeper roofs are harder and riskier to work on, leading to increased labor costs per square.
Material Type
Basic asphalt shingles cost much less than premium materials like metal, clay tile, or slate. Material choice heavily influences price per square.
Labor Costs in Your Area
Labor can account for up to 50–60% of the total cost. Prices vary by region, demand, and contractor experience.
Tear-Off and Disposal Fees
Removing the old roofing and disposing of debris can cost an additional $75–$150 per square, depending on material type and waste volume.
Structural Repairs
Damaged decking, underlayment, or flashing can add unexpected costs. Contractors often assess these after tear-off.
If you have a 1,600-square-foot roof (16 squares) and choose mid-grade architectural shingles at $550 per square:
Material & Labor: 16 squares × $550 = $8,800
Tear-Off & Waste Disposal: 16 × $100 = $1,600
Estimated Total Cost: $10,400
