When it’s time to tackle a roofing project, one of the essential questions you’ll face is, “How many bundles of shingles do I need?” Roofing materials can be a significant investment, so getting this right is crucial. In this blog, we’ll break down the calculations for a 10×10 roof, making it simple and straightforward.


Shingles are a popular roofing material due to their durability and ease of installation. To determine how many bundles you need for your roofing project, you’ll need to consider the size of your roof and the type of shingles you plan to use.

Calculating Shingle Bundles for a 10×10 Roof

A 10×10 roof covers an area of 100 square feet. The number of shingle bundles required depends on several factors, including the type of shingles you choose, their exposure, and the slope of your roof. Here’s a basic calculation using standard three-tab asphalt shingles:

  1. Measure Your Roof: Start by measuring the length and width of your roof in feet. For our 10×10 roof, you already know it’s 100 square feet.
  2. Check Shingle Coverage: Most shingle bundles are labeled with the coverage area. Commonly, a bundle of three-tab shingles covers approximately 33.3 square feet when installed correctly.
  3. Do the Math: To find out how many bundles you need, divide the total square footage of your roof by the coverage per bundle.
    Number of Bundles = Total Square Feet / Coverage per Bundle
    For our 10×10 roof using three-tab shingles:
    Number of Bundles = 100 square feet / 33.3 square feet per bundle ≈ 3 bundles

So, you would need approximately 3 bundles of three-tab shingles for a 10×10 roof.


Keep in mind that this is a basic estimate. It’s always a good idea to purchase a bit more than the calculated amount to account for any mistakes, repairs, or future needs. Additionally, if you’re using architectural shingles or specialty shingles with different dimensions, the coverage per bundle may vary, so be sure to check the manufacturer’s specifications.


Calculating the number of shingle bundles you need for a 10×10 roof is a straightforward process. By measuring your roof’s square footage and understanding the coverage of the shingles you plan to use, you can confidently purchase the right amount of materials for your roofing project. Remember to factor in some extra bundles for contingencies, and you’ll be well-prepared for a successful roof installation.
