Roofing projects often come with a lot of questions, especially if you’re tackling them as a homeowner or a budding DIY enthusiast.

One common query is about the number of shingle bundles required to cover a square foot of your roof. Let’s break this down in simple terms to help you understand and plan your roofing project effectively.


Before we dive into the specifics, it’s essential to grasp the basics. Shingle bundles are packages containing a specific quantity of shingles, typically designed to cover a certain area of your roof. The term “square foot” refers to the unit of measurement used to quantify roof size. Understanding how these two aspects relate is crucial for estimating your roofing needs accurately.

Shingle Bundles and Coverage

Shingle manufacturers often provide information about the coverage of a single bundle on the packaging or in the product specifications.

The coverage can vary based on the type and brand of shingles you choose. Common coverage measurements for a bundle of three-tab asphalt shingles are approximately 32 to 33.3 square feet per bundle.

Calculating the Number of Bundles

To calculate how many bundles of shingles you need to cover a specific square footage of your roof, follow these simple steps:

Step 1: Measure the square footage of your roof. This is done by multiplying the length by the width of each section of your roof and adding up the totals for all sections.

Step 2: Determine the coverage per bundle. As mentioned earlier, this information is usually provided on the shingle packaging.

Step 3: Divide the total square footage of your roof by the coverage per bundle. This will give you the approximate number of bundles needed.


Let’s say you have a roof with a total square footage of 1,000 square feet, and the shingles you’ve chosen have a coverage of 32 square feet per bundle.

  1. Measure your roof: 1,000 square feet
  2. Shingle coverage per bundle: 32 square feet

Now, divide the total square footage by the coverage per bundle:

1,000 square feet ÷ 32 square feet per bundle ≈ 31.25 bundles

In this case, you would need approximately 31.25 bundles to cover your 1,000 square foot roof. Since you can’t purchase a fraction of a bundle, you would typically round up to 32 bundles to ensure you have enough material to complete the job.


Estimating the number of shingle bundles you need for your roofing project is a straightforward process. By measuring your roof’s square footage and understanding the coverage provided by the shingle bundles you plan to use, you can make an accurate estimate. Always remember to round up to the nearest bundle to ensure you have enough shingles to complete your roofing job successfully.
