The term EPDM stands for ethylene propylene diene M-class rubber. EPDM is a black rubber product that is often used for roofing projects. EPDM roofs are single-ply membranes meaning that there is only one ply of roofing material and not multiple plies. EPDM has been used for roofing projects since the 1960s and is the one of the most common types of low-slope roofing materials. This is mainly due to its relative cheapness and its simplicity in the installation process.


The term TPO stands for Thermoplastic Polyolefin. TPO is actually in a broad family of rubber roofing materials. TPO is a blend of polypropylene andethylene-propylene rubber. TPO is the fastest-growing segment of the commercial roofing industry. It is generally a white membrane though there are different colors available. TPO is a seamless roof system. All the seams are heat welded together to make the roof totally seamless.


PVC stands for Polyvinyl Chloride. PVC is a flexible, thermoplastic membrane manufactured using an ultraviolet-resistant polyvinyl chloride. PVC is a pliable and durable sheet with excellent weathering characteristics and resistance to harsh chemicals and industrial pollutants. PVC roofing membranes are the ideal long-term solution for roofs that demand high performance at a lower life cycle cost.


BUR stand for Built Up Roof: Asphalt BUR is made up of multiple layers of reinforcing plies and asphalt forming a redundancy of waterproofing layers. The reflectivity of built up roofs depends on the surfacing material used. Gravel is the most common and they are referred to as asphalt or tar and gravel roofs.
