Shingle Coverage Calculator

The Shingle Coverage Calculator helps users determine how many bundles of shingles are required to cover a given roof area based on the coverage per bundle.

Background

When planning a roofing project, estimating the number of shingle bundles is critical for accurate budgeting and procurement. Shingles are commonly sold in bundles, with each bundle covering a specific area, usually around 33.3 square feet.

Formula

The basic calculation is:

\[ \text{Total Bundles Needed} = \frac{\text{Roof Area}}{\text{Coverage per Bundle}} \]

For example, if your roof area is 2000 square feet and each bundle covers 33.3 square feet:

\[ \text{Total Bundles Needed} = \frac{2000}{33.3} \approx 60.06 \text{ bundles} \]

Usage

This tool is ideal for homeowners, contractors, and DIY enthusiasts planning roofing projects. By inputting the roof area and coverage per bundle, the calculator quickly determines the total number of bundles required, helping avoid overbuying or running out of materials.
