Example Calculation
Scenario:
- Roof Size: 2,200 sq. ft.
- Material: Asphalt shingles at $4 per sq. ft.
- Labor: $3 per sq. ft.
- Additional Costs: $1,500 for removal and permits
Calculation:
- Material Cost = 2,200 × $4 = $8,800
- Labor Cost = 2,200 × $3 = $6,600
- Additional Costs = $1,500
Total Roof Replacement Cost = $8,800 + $6,600 + $1,500 = $16,900
