What is the typical measurement unit for net roof area in roofing?

Net roof area is typically measured in squares, which is a roofing unit that represents a surface area of 100 square feet. This unit is widely used in the roofing industry because it allows for a standardized way of discussing and calculating roofing materials and costs. When discussing roofing projects, using squares simplifies communication regarding area since roofing materials like shingles, underlayment, and insulation are often sold by the square.

The other measurement options are not appropriate for net roof area; linear feet refers to a length measurement and does not account for width or area. Cubic feet measures volume, which is irrelevant in this context as it relates to three-dimensional space rather than two-dimensional surface area. Acres, often used to measure large plots of land, would not be practical for the specific area of a roof. Thus, squares is the industry-standard unit for expressing net roof area.
