Roofing materials are estimated and sold by which measurement?

Roofing materials are typically estimated and sold by the measurement of a square, which specifically refers to an area of 100 square feet. This measurement is used in the roofing industry because it allows for easier calculation of the amount of material needed to cover a specific area of a roof. Using squares simplifies the planning process for roofing projects, providing clear standards for pricing and material quantities.

While square meters and linear feet are valid measurements for other construction elements, they do not align with the conventional practices in the roofing industry. Square meters are often used in regions that utilize the metric system, but square feet remains the prevalent standard in the United States, specifically for roofing. Linear feet is applicable for measurements along a line, such as the length of shingles but does not represent an area. Meanwhile, cubic yards are used for volumetric measurements, such as concrete or fill material, rather than flat surfaces like roofing.
