Built-Up Roofing in Fresno, CA
Dunlap Roofing Company
Asphalt flat roofs
The commercial built-up roof system, or asphalt flat roofing, consists of multiple plies of roof felts laminated with bitumen (typically asphalt). The asphalt or coal tar is heated in a kettle or tanker and then applied by mop or mechanical spreader. Cold-applied adhesives typically are solvent-based asphalts that do not have to be heated in a kettle or tanker. The most common surface for built up roof systems consists of gravel with a heavy application of asphalt or coal tar. 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 bottom most ply, is mechanically fastened. Built up roofs generally are considered to be fully adhered if applied directly to roof decks or insulation.
