About Modified Bitumen Roofing
The modified bitumen roofing system was first developed in Europe during the late 60’s and then introduced to the US in the early 70’s. The term “modified” refers to the addition of rubber or plastic-based polymeric binders to the asphalt or “bitumen” in order to improve its durability and performance. These roofing membranes are usually manufactured using one, two, or three plies.
The modified bitumen roofing system itself actually consists of multiple layers, meaning that it is really a “factory assembled” built up roof (Built Up Roofing, or BUR, is the traditional hot tar and gravel roof system that most people think of when they think of flat roofs.
During the manufacturing process, modifiers are added to standard roofing asphalt to replace the plasticizers that are removed during the distillation process. The bitumen is then reinforced with polyester fiber matting or fiberglass to increase its durability and strength. Most modified bitumen systems consist of a self-adhered base sheet and a cap sheet that has a granular surface.
Modified bitumen is an excellent choice on its own, but it also makes an excellent recover system to go over an existing BUR (old fashioned tar and gravel built up roof). Modified bitumen components are frequently used for repairs on old BUR roofs.
The benefits of modified bitumen roofing systems include the following:
- Easy to repair
- Flexible, contracts and expands making it suitable for rough weather conditions
- Relatively Easy installation
The disadvantages of modified bitumen roofing systems include the following:
- Hot process torch-down is not suitable for all buildings and substrates
- More labor intensive than single ply systems
- Not as resilient to ponding water as thermoplastic membranes like TPO or PVC
- Breaks down when subjected to chemicals, grease and fats, like one might find on restaurant or factory roofs.
