What is the total number of bundles that typically make a square of shingles?

The total number of bundles that typically make a square of shingles is generally three. A "square" in roofing terminology refers to an area that is 100 square feet. Most standard asphalt shingle bundles cover roughly one-third of a square, which means three bundles are needed to cover one square. This is an essential aspect of understanding roofing materials, as correct calculations ensure that the appropriate amount of materials is purchased for a roofing project. By knowing that three bundles are required to cover a square, builders can better estimate material needs and minimize waste during installation.
