What is Modified Bitumen Roofing?

A hybrid roofing system that is derived from built up roofing techniques combined with advanced roofing technology, modified bitumen roofing material is made up of high quality polymers reinforced with one or more layers of heavy duty polyester or glass fibers that offers superior strength and long lasting performance.

Top Benefits of Modified Bitumen Roofing

Property owners flock to modified bitumen roofing systems for a number of reasons. The tear-resistant nature of the material certainly makes it stand out from other roofing systems. For low-slope roofing systems that see a lot of foot traffic, a roofing system like this is an absolute must.

Not is modified bitumen tear-resistant, but it is also waterproof, too. While this might seem like an obvious benefit, this roofing system is much more waterproof than you might think. With layer upon layer of material applied to the roofing system, you won't have to worry about water-damaged underlayment any time soon.

Installation Options

As the name suggests, special modifiers are combined with standard roofing asphalt during a controlled refinement process where bitumen is then reinforced with fiberglass or polyester fiber to form sheets that provide superior strength and durability. Certified Bret Robben Roofing roofing experts offer two types of modified bitumen roofing materials:

SBS (Styrene Butadiene Styrene)

Installed with hot mopping of a cold adhesive  onto asphalt, this type of modified bitumen roofing can be further reinforced with an adhesive backing that provides a rubber type finish.

APP Atactic Polypropylene

Classified as a torch on roofing technique, APP modified bitumen is comprised of a thermoplastic polymer that is installed with heat applied applications (torch on or heat welded) that result in a smooth plasticized finish.

Available in rolls or sheets, modified bitumen roofing material is specifically manufactured to provide uniform thickness and state of the art components that are spread evenly throughout the material and carefully layered over the roof membrane. As esthetically appealing as they are practical, Bret Robben Roofing offers modified bitumen roofing systems in several granular color surfaces that offer excellent UV protection.

Our licensed and experienced roofing technicians combine one or more layers with additional built up roofing materials and techniques that result in flawlessly customized installations tailored specifically to the structural requirements of your commercial property.
