The Honest Exteriors Guide to Modified Bitumen Roofing for Flat Roofs

  • What is a modified bitumen flat roof made of?

    The ‘bitumen’ in the name of this flat roofing material is an asphalt emulsion that is soaked into roofing fabric to create a waterproof and fireproof roofing layer. More layers are added to create a seamless coat of protection over the flat roof surface.

  • Modified Bitumen Roof Layers

    Like other types of flat roofing systems, modified bitumen roofing is made up of layers of roofing materials. Here’s the layers for modified bitumen from bottom to top:

    • Flat roof decking
    • Asphalt emulsion base coat
    • Synthetic reinforcing fabric (fiberglass or polyester)
    • Base coat
    • Top coat
  • Advantages of Modified Bitumen Roofing

    • Durability – A modified bitumen flat roof system is very tear resistant because of the reinforcing fabric, which means they can handle foot traffic and storm debris.
    • Sun and Heat Resistance – With a light colored top layer, a modified bitumen roof is heat reflective, reducing UV rays and heat transfer.
    • Lower Energy Costs – The many layers of this kind of flat roofing are insulating. Combined with heat resistance, this makes modified bitumen roofing very energy efficient, an important feature with large commercial buildings.
