How is weight per square measured for roofing materials?

The appropriate way to measure the weight of roofing materials is in pounds per 100 square feet. This unit of measurement is commonly used in the roofing industry as it provides a standardized way to assess the weight and thus the structural requirements of roofing materials over a specified area. By expressing the weight in relation to a specific area (100 square feet), professionals can easily compare different materials and make informed decisions on their use in construction based on weight load and material performance.

Using pounds per 100 square feet ensures that roofers and builders can effectively plan for the installation, weight load considerations, and ensure compliance with building codes. Other options, such as square meters, kilograms per square foot, or ounces per square yard, do not align with industry standards for roofing material weight measurement and therefore may not facilitate proper assessment and comparison.
