Why Modified Bitumen Remains a Trusted
Commercial Roofing System
Modified bitumen roofing has been used on commercial buildings for decades because it combines proven waterproofing performance with modern material technology. Unlike traditional asphalt roofing, modified bitumen membranes are reinforced with polymers that improve flexibility, strength, and resistance to cracking.
Two of the most common systems are SBS (Styrene-Butadiene-Styrene) and APP (Atactic Polypropylene) modified bitumen. SBS membranes offer outstanding flexibility, making them especially well suited for Michigan’s cold winters and seasonal temperature fluctuations. APP systems provide enhanced UV resistance and are often selected for buildings exposed to prolonged sunlight.
Modified bitumen can be installed using torch-applied, cold-applied, or self-adhered methods, allowing the roofing system to be tailored to the building’s design, safety requirements, and project specifications. Its multiple reinforced layers create a durable, watertight membrane capable of resisting moisture intrusion, impact damage, and everyday wear.
For commercial properties with rooftop HVAC equipment or regular maintenance traffic, modified bitumen also offers superior puncture resistance compared to many single-ply roofing systems.
