Common Flat Roofing Systems

If you own a commercial building, knowing what type of flat roof you have will help you out when making decisions about maintenance and repair, and also allow you to work with companies that do commercial roofing in Johnson County, KS much better. To communicate with roofing contractors in Johnson County, here is some lingo on common flat roofing systems.

Built-up roofing system (BUR) is a very affordable flat roofing system and has been around for a very long time. It features layers of melted hot asphalt, separated by fiberglass, and then covered in pea-sized gravel. The gravel helps protect the asphalt from UV rays, which a premier roofing company in Overland Park would say is especially important. 


EPDM (ethylene propylene diene terpolymer) is a very recognizable roofing system that is affordable and easy for roofing companies in Johnson County to install. An EPDM roof is also known as a rubber roof as it is made of rubber. This roof typically adheres to the surface in large, lightweight sheets.  


Modified bitumen is chemically modified asphalt that is reinforced with fiberglass giving it a granulated look, and can be applied in a variety of ways. This roofing system performs especially well in cold weather, is extremely durable, seamless, and weather resistant. You can expect an MB roof to be around for a long time. 


Polyvinyl chloride (PVC) is one of the toughest materials for commercial roofing in Johnson County. The roofs’ membrane is exceptionally strong and durable. Additionally, the hot air welded seams of PVC roofing membranes give it a watertight bond, unlike the other roofing systems. PVC is resistant to chemicals, fire, weather, and the vinyl makes it environmentally friendly. 


Thermoplastic olefin (TPO) roofing membrane is a single-layered material typically white or gray in color and is either adhered to the surface or screwed in. Like the other roofing systems mentioned, TPO is heat- and UV-resistant, very durable, and affordable. 

Now that you know the different commercial roofing systems, which one does your building have?
