Modified Bitumen Roofing

Are you looking for an alternative to the common tar or asphalt roofing systems, but the only option for your roof is a Built Up Roof? There are alternatives to the traditional built up roofing systems that are available to you. A modified bitumen roofing system is one that has been around since the 1960s that combines the strength of asphalt or tar without the need (in some systems) to lift heavy buckets of the heated products to your roof.

Polymer-Modified Bitumen

While it might seem like this is a new technology, it really is not. It was developed around fifty years ago in Europe and began seeing applications in the US shortly after. The technology consists of using a fabric that is capable of absorbing bitumen (tar/asphalt), much like a traditional built up roof. Instead of using traditional tar or asphalt, this bitumen is modified by having some polymers, or plastics, added to it. This allows flexibility in the bitumen layer that is applied to the fabric. There are two main types of MB roofing:

  • SBS MB Roofing — These are applied with a traditional mopping method where a layer of fabric is placed down and then a liquid bitumen is mopped on top of it. In the case of the modified bitumen system, the liquid does not have to be heated and can be applied cold.
  • APP MB Roofing — These membranes are applied by being welded or torched in place instead of using a liquid adhesive. This could be a problem if you are applying APP to a wooden roof deck, so make sure that your roof deck can handle this heat.

The top surface of a MB roof can be anything from mineral coatings to foil laminates. They can also have a liquid applied over top for a smooth finish. The choice is up to you.
