Modified Bitumen
Modified bitumen membranes (or mod-bit) provide unparalleled reliability and serviceability. There are two kinds of modified bitumen systems;
- SBS (Styrene Butadiene Styrene) systems which can be applied with cold adhesives, hot asphalt, or torch-applied
- APP (Atactic Polypropylene) systems, which are almost exclusively torch-applied. This type of roofing is sometimes referred to as a torch-on roof.
Mod-bit systems provide several advantages including:
-
Durable and flexible in extreme weather – expands and contracts with the building
-
Easily maintained and repaired
-
Ease of install and factory quality controls
-
Wide variety of surface treatments to resist UV rays, reflect heat and match any décor
-
Reduced long-term costs and garbage load due to multiple cap layers
-
Peace of mind that only a two or three ply system can provide
