BUR, an acronym for built-up roofing, is one of the oldest methods for roofing a flat surface. Using several layers of roofing felt impregnated with asphalt and embedded in bitumen, BUR is applied with hot asphalt or coal tar pitch.

After it’s layered, roofers apply a coating of finely crushed stone granules to protect the surface from UV light and the elements.
