Thermoplastic polyolefin (TPO) Roof:
The term TPO stands for Thermoplastic Polyolefin. Believe it or not, TPO is actually in a broad family of rubber roofing materials. TPO is a blend of polypropylene and ethylene-propylene rubber.
TPO is probably the most widely used roofing product in the market today for two very good reasons: (1) it’s relatively cheap and (2) because it’s white. Cheap doesn’t always make something better, though. In fact, that is seldom the case
PVC Roof (Polyvinyl Chloride):
PVC membrane has excellent puncture and heat resistance qualities, it is absolutely incompatible with asphalt-based products. So any time a PVC roof is to be installed in such a way as to come in contact with any asphaltic product, separator sheets must be installed to keep the PVC from directly contacting the asphalt.
PVC is relatively light and can be purchased in milages between 36 and 90 mils (as mentioned before, a mil is 0.001 of an inch; 45 mils equal 0.045 inches). However, the standard PVC roofing membrane is between 40 and 60 mils. Though the primary color of a PVC roofing membrane is white, it can come in a variety of colors and hues. It also has excellent resistance to bacterial growth, animal fats, as well as plant roof penetrations.
EPDM (ethylene propylene diene terpolymer):
EPDM is a synthetic rubber, and it is fair to say that its main characteristic is that it is black. Some say ‘that’s good’ and some say ‘that’s bad.’ We think the market place has begun saying more and more ‘a black roof is bad.’ We say that for two important reasons. First, white roofing membranes have really been pushed. From the federal government down to local business owners, white roofing has really begun to take over and is being specified more and more. The second reason we feel that black EPDM has been considered a less than stellar option is because the market says so.
Hot Asphalt, Rubber Modified Bitumen:
Modified Bitumen (MB) roofing is an asphalt-based, designed for buildings with low-slope or “flat” roof structures.
Engineered modified bitumen roofing membranes originated in Europe in the mid 1960′s and have been used successfully in the United States and Canada since approximately 1975.
Increased resistance to brittleness at cold temperatures, greater flow resistance at high temperatures, and increased elasticity can be achieved by blending synthetic rubberized polymers with asphalt in lieu of modification by the blowing process used for BUR asphalt.
