When it comes to roofing, understanding the materials you need is essential. Roofing shingles are a crucial component of any roofing project, and one common question that arises is, “How many feet of cap do you get out of a bundle of shingles?”

In this blog, we’ll break down the concept of roofing cap, explain how it’s calculated, and provide practical examples to help you plan your roofing project more effectively.

What Is Roofing Cap?

Roofing cap, often referred to as hip and ridge cap, is a specialized type of shingle designed for the peak, hip, and ridge areas of your roof.

These areas are more vulnerable to water penetration and require extra protection. Roofing cap shingles are shaped to fit over the ridge and hip lines, creating a finished look while enhancing your roof’s weather resistance.

Calculating Roofing Cap Coverage

To determine how many feet of cap you can get out of a bundle of shingles, you need to consider the following factors:

  1. Shingle Type: Roofing cap shingles come in various sizes, and their length can vary. Commonly, they are 12 inches wide and 12 inches long, but this can differ based on the manufacturer.
  2. Roof Length: Measure the total length of the ridges and hips on your roof where you plan to install cap shingles. This measurement will determine how many linear feet of cap you need.
  3. Bundle Contents: Check the information provided on the bundle of cap shingles you purchase. Manufacturers typically specify the linear feet of coverage per bundle on the packaging.

Example Calculation

Let’s say you have a roof with a total ridge and hip length of 60 linear feet, and you purchase a bundle of cap shingles that provides 20 linear feet of coverage per bundle. Here’s how to calculate how many bundles you’ll need:

  • Total Linear Feet ÷ Linear Feet per Bundle = Bundles Needed
  • 60 linear feet ÷ 20 linear feet per bundle = 3 bundles

In this example, you would need three bundles of cap shingles to cover all the ridges and hips on your roof.


Understanding how many feet of cap you get out of a bundle of shingles is essential for accurately planning your roofing project. Remember that the specific coverage may vary depending on the manufacturer and the type of cap shingles you choose, so always check the bundle’s information for precise details.

Properly installing roofing cap shingles is crucial for protecting your roof’s most vulnerable areas from leaks and ensuring the longevity of your roof. If you’re not confident in your roofing skills, it’s advisable to consult with a professional roofer who can guide you through the process and ensure your roof is well-protected against the elements.

By calculating your roofing cap needs correctly, you can confidently tackle your roofing project and enjoy a finished roof that not only looks great but also provides the durability and protection your home deserves.
