Modified Bitumen Roofing System
- SBS polymer-modified bit membranes commonly are installed in hot moppings of asphalt or cold adhesive. Some membranes are self adhering.
- APP polymer-modified bit membranes typically are heat-welded or torch-applied.
Modified bitumen roof systems can be installed with the common torch method, asphalts, or cold adhesives. A standard SBS modified bitumen roof system is a two-ply system applied in rolls that overlap the edge of the previous roll.
