This tool will estimate the cost of your roof replacement based on your inputs for size, material, and labor.
Roof Estimate Calculator
This roof estimate calculator helps you quickly determine the estimated cost of roofing your house based on several key parameters:
- Roof Length: Enter the length of your roof in feet.
- Roof Width: Enter the width of your roof in feet.
- Roof Pitch: Enter the slope rise/run of your roof pitch.
- Cost per Square Foot: Enter the estimated cost per square foot for roofing materials and labor.
How to Use the Calculator:
- Fill in the requested measurements and costs in the input fields provided.
- Once all fields are filled, click the “Calculate” button.
- The estimated cost will appear in the result box below the button.
How It Calculates:
The calculator uses the input parameters to determine the total roof area and estimated costs. Specifically, the roof area is calculated using the formula:
Roof Area = Roof Length x Roof Width x sqrt(1 + (Roof Pitch/12)^2)
The estimated cost is then calculated by multiplying the roof area by the cost per square foot.
Limitations:
Please be aware of the following limitations:
- This calculator assumes a simple, rectangular roof shape.
- Additional costs related to complex roof structures, different materials, labor, permits, and other variables are not factored into this calculation.
Keep these limitations in mind and consider consulting with a professional for a more accurate and comprehensive roofing estimate.
