Built-Up Roof Systems
Built-up roofing systems, which have been used for almost 150 years, consist of multiple plies of reinforcing felts laid shingle fashion into continuous moppings of hot asphalt or cold adhesives. The system is then covered with aggregate set in an asphalt flood coat or final cold adhesive application. The plies can consist of organic membranes or glass fibre membranes.
Modified Roof Systems
This type of roof system uses modified bitumen membranes, which are factory-rolled products with rubberized or polymeric asphalt applied to one side at the factory. It can be installed by mopping on hot asphalt to adhere the membrane to the roof or, more commonly, by using a propane torch to heat the underside of the coating. Melting to a near-liquid, the membrane is then rolled onto the roof in a continuous operation.
Thermoplastic Roof Systems
This roofing system is similar to the EPDM system. However, its synthetic single-ply membrane sheets are made of a number of other materials, most commonly polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO). These membranes are available in a variety of thicknesses and colours.
