Formula for Roof Replacement Cost
The general formula is:
Total Cost = (Roof Area × Material Cost per sq ft) + (Roof Area × Labor Cost per sq ft) + Additional Costs
Where:
- Roof Area = total square footage of the roof.
- Material Cost per sq ft = cost based on roofing type.
- Labor Cost per sq ft = installation cost.
- Additional Costs = permits, removal of old roofing, disposal fees, etc.
Example Calculations
Example 1: Asphalt Shingle Roof
- Roof Area: 2,000 sq ft
- Material Cost: $3 per sq ft
- Labor Cost: $2 per sq ft
- Additional Costs: $800
Calculation:
Material Cost = 2,000 × $3 = $6,000
Labor Cost = 2,000 × $2 = $4,000
Total = $6,000 + $4,000 + $800 = $10,800
Example 2: Metal Roof
- Roof Area: 1,800 sq ft
- Material Cost: $7 per sq ft
- Labor Cost: $3 per sq ft
- Additional Costs: $1,200
Calculation:
Material Cost = 1,800 × $7 = $12,600
Labor Cost = 1,800 × $3 = $5,400
Total = $12,600 + $5,400 + $1,200 = $19,200
Factors Affecting Roof Replacement Costs
- Roof Size and Complexity – Larger roofs or roofs with multiple slopes and valleys cost more.
- Material Choice – Premium materials like slate or clay tiles can be several times more expensive than asphalt shingles.
- Labor Rates – Higher in urban areas or where roofing contractors are in short supply.
- Old Roof Removal – Removing and disposing of the old roof adds to costs.
- Roof Pitch – Steeper roofs are harder to work on and may increase labor charges.
- Weather Conditions – Adverse weather can delay projects and increase costs.
- Permits and Inspections – Some regions require paid permits before roofing work begins.
