Answer: (B)

One roofing square is defined as a unit of measure in the roofing industry that represents an area of 100 square feet. This term is commonly used to help roofing professionals quantify material needs and estimate job costs accurately. By using squares to describe quantities of roofing materials, such as shingles or insulation, it simplifies communication and calculations.

The concept of using squares is particularly useful given that roofing materials are often sold in bundles that cover a certain number of squares. Knowing that one roofing square equals 100 square feet allows for clear and efficient planning in roofing projects, making it essential for roof observers and contractors to understand this unit of measure fully. This knowledge aids in determining how many squares of material are needed based on the total roof area, ensuring accurate estimates and efficient material usage.
