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.


The benefits of a modified bitumen roofing system include:

  • durability
  • weather-resistant
  • time-tested technology
  • flexibility
  • thickness of material
  • ease of repair
