Similar to residential roofing, commercial roofing varies in a lot of ways. For one, a popular type used by many businesses is called a built-up roofing system, wherein layers of felt are placed in between the asphalt to add strength and stability. Its composition, as well as its layering structure, was briefly mentioned in an article posted on nrca.net:
Built up roof membranes, referred to by the acronym BUR, have been in use in the U.S. for more than 100 years. These roof systems are commonly referred to as “tar and gravel” roofs. BUR systems generally are composed of alternating layers of bitumen and reinforcing fabrics that create a finished membrane. The number of plies in a cross section is the number of plies on a roof: The term “four plies” denotes a four ply roof membrane construction. Sometimes, a base sheet, used as the bottommost ply, is mechanically fastened. Built up roofs generally are considered to be fully adhered if applied directly to roof decks or insulation.
These systems are can be modified to be made of a combination of different materials like asphalt or rubber to achieve maximum durability. Another type is made of a single-ply material called thermoplastic roofing, which is known for its elasticity. It can stretch farther than others, and this is ideal for buildings along fault lines and unstable areas to cope with movement caused by earthquakes or landslides.
