This roofing square calculator will help you easily determine the amount of roofing material you need for your project.

## Roofing Square Calculator

This roofing square calculator allows you to calculate the total square footage of a roof based on its length, width, and pitch. This can be helpful in determining how much roofing material you need.

### How to Use the Calculator

- Enter the length of the roof in feet.
- Enter the width of the roof in feet.
- Enter the pitch of the roof. The pitch is the rise of the roof over a 12-inch run. For example, if the roof rises 6 inches for every 12 inches it runs, the pitch is 6.
- Click the
**Calculate**button to get the total square footage of the roof.

### How It Calculates

The calculator uses the following steps to compute the area:

- First, it derives the pitch multiplier using the formula:
`sqrt(1 + (pitch / 12)²)`

. - Then, it multiplies the length and the width to get the total area without pitch.
- Finally, it multiplies the total area by the pitch multiplier to get the actual area considering the pitch.

### Limitations

Please note the following limitations of this calculator:

- All inputs must be positive numbers.
- The pitch must be a non-negative number.
- This calculator assumes a simple rectangular roof. For complex roofs, additional calculations or considerations may be needed.
