Reroof Cost Calculator
What is a Reroof Cost Calculator?
A Reroof Cost Calculator is a digital tool that estimates the total cost of replacing or repairing a roof. It takes into account:
- Roof Size – Measured in square feet or roofing squares.
- Roofing Material – Shingles, metal, tiles, or other types.
- Labor Costs – Installation, removal of old roofing, and extra labor charges.
- Additional Expenses – Permits, disposal fees, insulation, and underlayment.
- Complexity Factors – Roof pitch, number of stories, and architectural features.
By combining these factors, the calculator generates an accurate cost estimate for the entire roofing project.
Formula for Reroof Cost Calculation
The general formula is:
Total Cost = (Roof Area × Material Cost per Sq Ft) + Labor Costs + Additional Expenses
Where:
- Roof Area = Total square footage of the roof
- Material Cost per Sq Ft = Cost of chosen roofing material per square foot
- Labor Costs = Estimated labor charges for removal and installation
- Additional Expenses = Permits, disposal, underlayment, and insulation
This formula ensures a detailed and precise estimate for homeowners and contractors.
How to Use the Reroof Cost Calculator

Example Calculations
Example 1 – Asphalt Shingle Roof
- Roof Area: 2,000 sq ft
- Material Cost: $3 per sq ft
- Labor Cost: $4,000
- Additional Expenses: $800
Calculation: (2,000 × 3) + 4,000 + 800 = $10,400
Result: Estimated reroof cost = $10,400
Example 2 – Metal Roof
- Roof Area: 2,500 sq ft
- Material Cost: $7 per sq ft
- Labor Cost: $6,000
- Additional Expenses: $1,200
Calculation: (2,500 × 7) + 6,000 + 1,200 = $24,700
Result: Estimated reroof cost = $24,700
Example 3 – Tile Roof
- Roof Area: 3,000 sq ft
- Material Cost: $10 per sq ft
- Labor Cost: $8,000
- Additional Expenses: $2,000
Calculation: (3,000 × 10) + 8,000 + 2,000 = $40,000
Result: Estimated reroof cost = $40,000
