Understanding Shingle Coverage How Many Square Feet Does a Pack Cover : Learn the Essentials of Roofing Shingle Coverage

When planning a roofing project, understanding how much area a pack of shingles covers is essential for buying the right materials and avoiding costly mistakes. In the U.S., shingles are typically sold by the “bundle” or by the “square.” A “square” in roofing terminology refers to an area of 100 square feet. Most asphalt shingles are packaged so that three bundles cover one square, though this can vary depending on the brand and style.

On average, a single bundle of standard asphalt shingles covers approximately 33.3 square feet. This means you’ll need three bundles to cover a 100-square-foot section of roof. Premium or architectural shingles may cover slightly less per bundle due to their increased thickness or unique shapes, sometimes requiring four bundles per square. It’s also important to account for roof pitch, waste from cutting, and starter/edge shingles, which may increase the needed material by 10–15%.

As a designer, accuracy and thorough planning are foundational—measuring your space precisely will ensure you order the right quantity of material, minimize waste, and achieve a clean, professional result. To visualize how new shingles will complement your home’s style or to simulate material quantities, you might find a tool like a home designer platform especially useful.

Tips 1:

Always check the manufacturer’s specifications on the packaging, as coverage can vary, and verify whether the stated coverage includes allowances for overlap and waste, especially if your roof has complex shapes or features like valleys, dormers, or multiple ridges.
