This tool calculates the total square footage of your roof based on dimensions you provide.

### How to Use the Roof Square Footage Calculator

To use this calculator, input the following parameters:

**Length:**The length of your roof in feet.**Width:**The width of your roof in feet.**Roof Pitch:**The pitch of your roof in rise/run format (e.g., 4/12).

After entering the values, click the “Calculate” button to see the total roof square footage.

### How it Calculates the Results

The roof square footage calculator works by calculating the effective area of the roof based on its size and pitch. The formula it uses is:

- First, it converts the pitch into a slope factor using the equation:
*slope factor = √(1 + (rise/run)²)*. - It then multiplies the dimensions (length and width) by the slope factor to adjust for the pitch.
- The result is the total roof area in square feet adjusted for the pitch.

### Limitations

While this calculator provides a good estimate, it has the following limitations:

- It assumes a simple rectangular roof shape. For more complex roof designs, additional calculations will be needed.
- It does not account for features like dormers or overhangs, which will need to be calculated separately and added to the total.
- Ensure all measurements are taken accurately for the best results.
