Traditional built-up roofing is abbreviated as BUR. What is another name for it?

Traditional built-up roofing, abbreviated as BUR, is commonly referred to as tar-and-gravel roofing. This name accurately captures the key components of this roofing system, which consists of layers of bitumen (tar) and a protective gravel surface. The gravel serves several purposes: it adds weight to the roofing system to protect it from wind uplift, it provides UV protection for the underlying materials, and it helps to dissipate heat.

The other terms mentioned are either inaccurate or do not widely represent the BUR system. For instance, "punch-and-gravel" does not correspond to any established roofing terminology, and while "coal-and-tar" may refer to a specific type of bitumen material, it is not a recognized name for the traditional built-up roofing system. Likewise, "fiberglass roofing" refers to a different type of roofing material that utilizes fiberglass for its structural integrity and does not relate to the tar-and-gravel method used in built-up roofing. Thus, tar-and-gravel stands out as the correct and most recognized alternative name for BUR.
