Formula Used in the Calculator
The calculator generally uses the following cost estimation formula:
Total Cost = (Roof Area × Material Cost per Unit) + Labor Cost + Removal Cost + Additional Feature Costs
Where:
- Roof Area = Total surface area of the roof
- Material Cost per Unit = Price per square foot/meter for the chosen material
- Labor Cost = Estimated labor charges for installation
- Removal Cost = Cost for dismantling and disposing of old roofing
- Additional Features = Cost for skylights, chimneys, ventilation, etc.
Example Calculation
Example 1:
- Roof Area = 2,000 sq. ft
- Material Cost = $4 per sq. ft
- Labor Cost = $3,000
- Removal Cost = $1,000
- Additional Features = $500
Calculation:
Material Cost = 2,000 × $4 = $8,000
Total Cost = $8,000 + $3,000 + $1,000 + $500 = $12,500
Example 2:
- Roof Area = 1,500 sq. ft
- Material Cost = $6 per sq. ft (metal roof)
- Labor Cost = $2,500
- Removal Cost = $800
- Additional Features = $0
Calculation:
Material Cost = 1,500 × $6 = $9,000
Total Cost = $9,000 + $2,500 + $800 = $12,300
