Shingle Coverage Calculator Calculator Usage Guide

Learn how to use the Shingle Coverage Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the length of your roof in feet in the "Roof Length" field.
  2. Enter the width of your roof in feet in the "Roof Width" field.
  3. The "Shingle Coverage" field typically defaults to 33 square feet per shingle, but you can adjust this if your shingles have a different coverage area.
  4. Click the "Calculate" button to determine the total number of shingles needed.
  5. The result will be displayed in the "Total Shingles Needed" field.

Understanding the Formula

The calculator uses the following formula to determine the number of shingles needed:

Total Shingles Needed = (Roof Area / Shingle Coverage)

Where:

  • Roof Area is calculated by multiplying the length and width of the roof.
  • Shingle Coverage is the number of square feet that a single shingle can cover, which is typically provided by the shingle manufacturer.

Important Notes

This calculator provides an estimate based on the input dimensions and shingle coverage. It is important to add a buffer of additional shingles (typically 10-15%) to account for waste, cutting, and potential issues during installation.
