Roofing Calculator
How to Use the Roofing Calculator
- Enter the Length of your roof in feet.
- Enter the Width of your roof in feet.
- Enter the Pitch of your roof in degrees.
- Enter the Cost of Shingles per square foot.
- Enter the Labor Cost per square foot.
- Click the Calculate button.
The calculator will display the total roof area and the total cost based on your inputs.
Explanation of the Calculations
The total roof area is calculated using the formula:
Total Roof Area = (Length x Width) x (1 + (Pitch รท 90))
The total cost is calculated using the formula:
Total Cost = Total Roof Area x (Cost of Shingles + Labor Cost)
Limitations
This calculator assumes a single, simple rectangular roof section and uniform costs. Complex roof designs or variable costs would require a more detailed analysis.
