This tool helps you calculate the total square footage of your roof.
How to Use the Roofing Square Footage Calculator
- Enter the length of the roof in feet into the “Roof Length” field.
- Enter the width of the roof in feet into the “Roof Width” field.
- Enter the roof pitch, typically a number between 1 and 12, into the “Roof Pitch” field.
- Enter the waste factor percentage, or leave it at the default value of 10%, into the “Waste Factor” field.
- Click the “Calculate” button to compute the total square footage needed, factoring in the pitch and waste factor.
Calculation Explanation
This calculator determines the total square footage of roofing material needed by:
- Calculating the base area as
length * width. - Adjusting for the roof pitch using the pitch multiplier formula
Math.sqrt(1 + Math.pow(pitch / 12, 2)). - Factoring in a waste percentage to account for material waste and complex cuts.
Limitations
This calculator provides an estimate based on the measurements and values entered. It may not always account for all variations in roof design, such as valleys, dormers, or other architectural features. Always consult with a roofing professional for an accurate assessment.
