| Built-Up roofing is sometimes referred to as "Hot Tar" roofing; they are one and the same.This roofing is comprised of several alternating layers of rolled out fiberglass based materials and molten tar. First, a layer of "Base Paper" is nailed down to the prepared surface. This layer serves as a buffer between the structure and the roofing material. It allows for some structural shifting without damaging the roofing and provides a high quality surface on which to bond the roofing.
Next an asphalt-impregnated roll of fiberglass is applied to the base layer using molten tar. This molten tar melts and bonds with the asphalt in the fiberglass, in effect binding them into one. This step is repeated two to five times, depending on the warranty wanted, but two or three is most common and extremely effective.
At this stage there are two options. Either an emulsion/UV block can be applied as a final coat or a granulated cap sheet mopped on with molten tar.
