What does a "Square of shingles" measure?

A "Square of shingles" is a specific measurement unit used in the roofing industry to denote an area coverage of roofing materials. When we say a square of shingles, we are actually referring to an area of 100 square feet. This standard measurement assists roofing contractors, builders, and suppliers in quantifying and pricing roofing materials effectively.

Understanding this measurement is essential in estimating the amount of shingles needed for a roofing project, as it allows professionals to calculate the total number of squares required based on the total square footage of the roof. For example, if a roof has an area of 1,500 square feet, it would require 15 squares of shingles since each square covers 100 square feet.

The other options relate to roofing but do not accurately define what a square of shingles measures in area.
