Flat Roof Systems:
Asphalt Built Up Roof
Asphalt is an aliphatic compound and in almost all cases a byproduct of the oil industry. Some asphalt is manufactured from oil as the intended purpose, and this is limited to high quality asphalt produced for longer lasting asphalt built-up roofs. Asphalt BUR is the most common type of flat roof at this time. It is made up of multiple layers of reinforcing plies and asphalt forming a redundancy of water proofing layers. The reflectivity of built up roofs depend on the surfacing material used.
A self-adhering roofing system is comprised of a nailable base or self-adhering ply base with a top surface designed to accept a self-adhering roofing membrane, a self-adhering mid ply and a self-adhering cap sheet. Self-adhering roofing systems offer several advantages for contractors: no torches, no hot asphalt, no fumes and no mess — all of which means application is much cleaner and faster. Self-adhering roofs are also environmentally friendly because there are no volatile organic compounds in the material. Other advantages of self-adhering roofing systems are the ease of application, minimal equipment requirements and a cleaner work environment. These advantages are even more amazing considering the long system life you can expect.
