Why Commercial Modified Bitumen Roofing?

An excellent choice for flat or low-slope commercial roofing systems. Modified bitumen, as it’s used for roofing, is a material made of a bitumen substance- a mix of asphalt and/or black hydrocarbon, petroleum-based materials- mixed with rubber or plastic modifiers such as atactic polypropylene or styrene butadiene styrene. These modifiers give the sturdy, bitumen a flexible and durable quality that allows for easier installation and modification of roofing systems. Modified bitumen is an excellent choice for flat or low-slope commercial roofing systems because it is installed by rolls, using methods that work best on a surface without a steep incline.

Commercial Modified Bitumen Roofing

Modified Bitumen is the thickest “membrane” roofing available, has a long useful lifespan and is incredibly durable. It is durable against punctures from debris and foot traffic. This roofing system also has excellent chemical resistance and is available in a white/reflective surface type.  Modified Bitumen roofs can be used as multiple ply systems, where two roofs are installed at once, which will ensure the roof has a very long life.

Modified Bitumen Roofing Options

Modified bitumen roofing is of two types: Styrene-Butadiene-Styrene (SBS) and Atactic Polypropylene (APP). Each has its own advantages, and an experienced contractor can help you find the right roofing system.

  • SBS

    SBS is elastomeric bitumen and it can stretch which offers improved flexibility and increases its contraction and expansion capabilities.

  • APP

    APP can improve the stability of your roof over time. APP is a plastomeric bitumen that is made flexible with an elastic plastic. An APP roof covering is more UV-resistant then its SBS counterpart.
