Modified Bitumen

Modified bitumen systems combine the advantages of built-up roofing with the ease of application of a single-ply system. Bitumen is reinforced with fiberglass or polyester for added durability, it is then made into sheets or rolls for ease of application. 

The two kinds of Modified bitumen systems:

  • SBS (Styrene Butadiene Styrene) systems usually installed with hot asphalt or cold adhesives.

  • APP (Atactic Polypropylene) systems in almost every case are installed using the torch method.


  • Durability throughout extreme weather

  • Easily repaired

  • Ease of application

  • Factory-manufactured to ensure quality

  • Expand or contract with the building's movement

  • A variety of surface materials that resists oxidation and damage from UV radiation.
