Membrane roofing systems have many advantages. One of the best-known ones is modified bitumen, which is commonly known as rolled-up roofing.
What Is Modified Bitumen?
Bitumen is the technical term for asphalt. Rubber modifiers and solvents combine to give asphalt a more heat-resistant finish, hence the name modified bitumen. Installation of this roofing system can vary – from heat application to cold-applied adhesives. One distinct advantage heat seals have over other applications is that the finish becomes seamless, thereby resolving a common issue faced by rolled-up roofing systems.
Advantages Over Asphalt
Asphalt has been used as a roofing system for quite some time, but changes in temperature cause frequent expansion and contraction. This makes the roof susceptible to cracking, and, over time, leakage will inevitably occur in the cracks.
The synthetic rubber additives in modified bitumen roofing do not entirely prevent the asphalt from expanding and contracting from the sun’s heat. It does, however, create a crack-free seal that allows the surface to remain waterproof over longer periods.
Finally, asphalt typically needs gravel to weigh it down as heat can cause it to degrade much faster. Modified bitumen roofing forgoes the gravel in favor of more effective heat seal applications that create better protection against wear and tear as well as water damage.
