Roof Shingles Calculator: Estimate Roofing Costs

This tool helps you easily estimate the number of roof shingles you need for your roofing project.

Roof Shingles Calculator




How to Use the Roof Shingles Calculator:

Enter the length and width of your roof in feet. Additionally, specify the roof slope in degrees to account for the pitch. Click on “Calculate” to get the total area in square feet and the number of shingles required.

Calculation Method:

The calculator uses the following steps to determine the number of shingles required:

  • Calculates the area of the roof surface considering its slope.
  • Assumes standard shingles coverage per bundle (33.3 square feet).
  • Adds 10% extra for wastage (cuttings, overlaps, etc.).

Limitations:

This calculator assumes a simple, gable roof and does not account for dormers, chimneys, or other features that could affect the total shingle requirement. Always consult with a roofing professional for more complex calculations.
