In a square of 3-tab shingles, how many bundles does it contain?

A square, in roofing terminology, refers to an area that measures 100 square feet. When dealing with 3-tab shingles, it is important to recognize that a standard bundle typically covers approximately 33.3 square feet. Therefore, to determine how many bundles are needed to cover one square, you would take the total area of the square (100 square feet) and divide it by the coverage of one bundle (33.3 square feet).

The calculation would be:

100 square feet / 33.3 square feet per bundle ≈ 3 bundles.

This means that within one square of 3-tab shingles, there are roughly three bundles required to achieve full coverage. Understanding this relationship is crucial for accurately estimating roofing materials and ensuring a project is completed efficiently without shortfalls or excess material.
