Modified Bitumen

Modified Bitumen

Modified Bitumen Roofing (MB) is another option with it being self-adhered making it quick, easy, and clean for commercial roofers to install properly and in a timely manner. When applied properly, self-adhered roofing can deliver the same protection as those applied by hot asphalt or cold adhesive for a cost-efficient solution adhering to the same results as those with EPDM or TPO roofs.

To help decide whether this is the best option for you and your building, there are things you must consider before installing.

You must have the proper tools, though easy to apply, it’s important to have these on hand:

  • Weighted roller used for pressing the membrane into the proper place
  • A suitable towel for applying adhesive to flashing details if not using a hot air welder
  • Caulk gun for applying the adhesives (if needed)
  • Seam probing tool to check for small holes or leaks


With Modified Bitumen Roofing, there’s a 5 layer-installation system that needs to be in place in order to be installed properly:

  1. Insulation: which is used to provide the “R” value, or thermal, resistance so there’s temperature stability in the roofed rooms
  2. Modified Based sheets or Plies
  3. Modified MB Membranes: this is the factory-fabricated sheet membrane composed of co-polymer mixed with fiberglass or polyester
  4. Adhesive: waterproofing material with a bonding agent that can be applied either hot or cold depending on the preference
  5. Surfacing: which provides UV protection and acts a weather-resistant


Beyond all of this, there are several benefits to being able to use Modified Bitumen Roofing such as:

  • A great reputation in the roofing industry
  • Top-notch waterproofing resistance 
  • Long-term warranties
  • Competitive life-cycle costs
  • Several ranges of installation and application methods
