### How to Use the Roof Replacement Calculator:

This calculator helps you estimate the total cost of replacing a roof. Here’s how you can use it:

**Length of Roof:**Enter the length of the roof in feet.**Width of Roof:**Enter the width of the roof in feet.**Pitch of the Roof:**Select the pitch of the roof. The pitch determines the slope of the roof.**Cost per Square Foot:**Enter the cost of roofing materials per square foot.**Waste Factor:**This is the percentage of material that will be wasted during the roofing process. The default value is 10%.

Click the “Calculate” button to get the estimated total cost of replacing the roof.

### Explanation of Calculation:

The calculation is performed as follows:

- The area of the roof is calculated by multiplying the length and width and adjusting for the pitch.
- The waste factor is added to the area to account for extra materials needed.
- The total cost is then calculated by multiplying the adjusted area by the cost per square foot.

### Limitations:

This calculator provides an estimate and may not account for additional costs such as labor, permits, or removal of the old roof. For an accurate quote, please consult a professional roofing contractor.
