FLAT ROOFING SERVICES
Modified Bitumen Roofing Membranes
Illinois Roofmasters installs polymer-modified bitumen or modified bitumen (MB) sheet membranes on flat roofs of all types throughout Chicagoland. These flat roof membranes were developed in Europe in the early 1960s and have been trusted for use against all types of weather across the U.S. since the mid 1970s.
Polymer-modified roof membranes are composed of reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen as it is manufactured into a roll material. MB roof system membranes are composed of multiple layers, much like BUR membranes. MB roof systems typically are installed as a two-ply system and almost always are fully adhered.
Roofing Membrane - Modified Bitumen
There are two types of Modified Bitumen roofing membranes:
SBS polymer-modified bitumen membranes commonly are installed in hot moppings of asphalt (similar to BUR systems) or cold adhesive. Some SBS modified membranes are self-adhering; that is, they contain an adhesive backing.
APP polymer-modified bitumen membranes typically are heat-welded or torch-applied.
