Why Commercial Modified Bitumen Roofing?

An excellent choice for flat or low-slope commercial roofing systems. Modified bitumen roofing material is 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 bitumen a sturdy, flexible, and durable quality that allows for easier installation and modification. Modified bitumen is an excellent choice for flat or low-slope commercial roofing systems because it is installed by rolls.

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.

9

SBS

  • SBS is elastomeric bitumen and it can stretch which offers improved flexibility and increases its contraction and expansion capabilities.
9

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 than its SBS counterpart.
