Choosing the right shingles
When embarking on a roofing project, selecting the appropriate shingles is a crucial decision.
Homeowners often find themselves wondering about the coverage provided by a bundle of shingles. Let’s delve into the factors that influence this and explore how to determine the square footage covered by a bundle.
Shingle size matters
The size of the shingles plays a significant role in determining the coverage. Shingles come in various dimensions, and it’s essential to consider both the length and width. Standard asphalt shingles typically measure 12 inches in width and 36 inches in length, covering an area of 1 square (100 square feet) when installed with the recommended overlap.
Understanding the bundle
Shingles are commonly packaged in bundles, with each bundle containing a specific quantity. Manufacturers specify the coverage on the packaging, expressing it in squares. A bundle typically covers 1/3rd of a square or approximately 33.3 square feet, but this can vary based on the brand and type of shingle.
Calculating coverage
For accurate coverage estimation, you’ll need to know the total square footage of your roof. Measure the length and width of each section, multiply these figures, and then add them together to get the total square footage. Once you have this number, divide it by the coverage provided by a single bundle to determine how many bundles you’ll need.
Factoring in waste and overlaps
It’s essential to account for waste and overlaps during the installation process. Shingles are designed to overlap, providing a waterproof barrier. Additionally, some waste occurs due to the trimming required to fit shingles along the edges and around roof features. A good rule of thumb is to add 10% to your total bundle count to accommodate for these factors.
Consider the roof pitch
The pitch or slope of your roof also affects the coverage of shingles. Steeper roofs may require more shingles to cover the same square footage compared to a flatter roof. Manufacturers often provide guidelines on how to adjust the quantity of shingles based on the roof pitch, ensuring proper coverage and performance.
Consulting with professionals
When in doubt, it’s advisable to consult with roofing professionals or the manufacturer. They can provide specific guidance based on the type of shingles you’ve chosen and the unique characteristics of your roof. Their expertise can help you avoid miscalculations and ensure a successful and long-lasting roofing project.
Understanding how many square feet a bundle of shingles will cover is a crucial aspect of planning any roofing project. By considering factors such as shingle size, bundle coverage, waste, overlaps, and roof pitch, homeowners can make informed decisions and ensure their roofing endeavors are both cost-effective and durable.
