How much does mineral surface rolls typically weigh per square?

Mineral surface rolls typically weigh around 90 pounds per square. A "square" is defined in roofing terminology as a unit of area that covers 100 square feet. This weight is characteristic of mineral-surfaced roofing materials, which are commonly used for flat roofs due to their durability and water-resistant properties.

Understanding the weight is important for construction and installation purposes, as it impacts the handling, the structural load on the building, and the amount of material needed for a roofing project. The weights of other choices do not accurately reflect standard industry practices for mineral surface rolls, which is why they are less suitable for this particular question.
