Understanding the Coverage of Asphalt Shingle Bundles
Asphalt shingles are one of the most popular roofing materials in North America, favored for their affordability, durability, and variety of designs. Homeowners and contractors alike often seek to understand how much area one bundle of these shingles can cover to effectively plan roofing projects. This article aims to clarify the coverage provided by a standard bundle of asphalt shingles and offer some guidance on purchasing the right amount for your roofing needs.
Understanding the Coverage of Asphalt Shingle Bundles
When calculating the number of bundles needed for a roofing project, it is essential to first determine the total area of the roof. To do this, measure the length and width of each section of the roof, considering any dormers or valleys, and multiply these dimensions to get the total square footage. For instance, if a roof measures 20 feet by 25 feet, the total area would be 500 square feet.
Once you have the total square footage, you can convert this figure into roofing squares. A roofing square is a common roofing measurement that equals 100 square feet. Therefore, to find the number of squares needed, divide the total square footage by 100. In the previous example, 500 square feet divided by 100 equals 5 squares.
Since each bundle covers approximately 33.3 square feet, you can determine the number of bundles required by dividing the total square footage by the coverage area per bundle. Continuing with our example, 500 square feet divided by 33.3 square feet per bundle equals about 15 bundles (when rounded up).
It’s crucial to remember that this is a general estimate and does not account for necessary waste, overlapping, or mistakes. Roofing work usually generates waste—typically about 10-15% of the total material. Consequently, it's advisable to order additional bundles to accommodate this waste. For our example, adding 10% means purchasing an extra one or two bundles, totaling around 16-17 bundles.
In summary, while a standard bundle of asphalt shingles generally covers around 33.3 square feet, accurately calculating the necessary amount involves considering the total roof area and potential waste. Proper planning ensures that your roofing project runs smoothly, minimizing disruptions and extra costs. Remember to consult with local suppliers for specific coverage details and recommendations based on the shingles you choose. This knowledge will help you make informed decisions and achieve a durable, aesthetically pleasing roof.
