This tool calculates the total area of your roof and provides an estimate of materials needed.
How to Use the Roof Pitch Calculator
To use the roof pitch calculator, please follow the steps below:
- Enter the length of your roof in feet.
- Enter the width of your roof in feet.
- Enter the slope of your roof as a rise over run (for example, for a rise of 6 inches over a run of 12 inches, enter 0.5).
- Optionally, enter the overhang in feet if your roof has an overhang.
- Click the “Calculate” button to calculate the roof pitch and total area.
Explanation of the Calculation
The roof pitch is calculated using the arctangent of the slope, converting the result from radians to degrees. The area of the roof is calculated by determining the length of the roof surface on one side and then multiplying it by the total length of the roof. The result is then doubled as the roof has two sides.
Limitations
This calculator assumes a simple gable roof without any additional complexity like dormers or varying slopes. Input values must be positive numbers and non-zero. The precision of calculations is limited to standard decimal rounding conventions.
