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.
