This tool calculates the total square footage of your roof based on your input.
How to Use the Roof Square Calculator
This calculator helps you estimate the square footage of your roof. To use the calculator:
- Enter the length of the roof in feet.
- Enter the width of the roof in feet.
- Enter the pitch (angle) of the roof in degrees.
- Click “Calculate” to get the result.
How the Calculator Works
The roof square calculator uses the following formula to calculate the area:
- Roof Area (sq ft) = Length (ft) × Width (ft) × Pitch Factor
The pitch factor is calculated based on the pitch angle using the following formula:
- Pitch Factor = √(1 + tan²(Angle in Radians))
Where the angle in radians is computed as:
- Angle in Radians = Pitch (degrees) × π/180
Limitations
This calculator provides an estimate based on simple geometrical principles and assumes a rectangular roof with a single pitch angle. It may not account for complex roof shapes or multiple pitches, so for more complicated roofs, you may need a more detailed calculation or consult a professional.
