Roofing Square Calculator | Measure Your Roof Accurately

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:

  1. First, it derives the pitch multiplier using the formula: sqrt(1 + (pitch / 12)²).
  2. Then, it multiplies the length and the width to get the total area without pitch.
  3. 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.
