EPDM (Ethylene Propylene Diene Monomer) membrane - also known as rubber - has excellent weathering characteristics because of it durability meaning its ability to stretch and maintain that resilience over a longer period of time when compaired to other single plies giving it the highest capacity of the single plies to resist hail damage on it own merits. EPDM and its components are adhered together with tapes and adhesives. EPDM, traditionally black in color, is now also offered in white. EPDM is manufactured in different membrane thicknesses. A fully-adhered EPDM roofing system installed under the right conditions offer simple long term maintenance care, giving your roof a chance to be serviced well into the future.
TPO (Thermoplastic Polyolefin) & PVC (Polyvinyl-chloride) membranes - also known as plastics - are light colored (typically white, tan or gray) and are known as 'cool roofs' because of their ability to reflect the sunlight reducing the roof's temperature, thereby reducing heat gains and air conditioning costs. TPO and its components are held together using a combination of adhesives and heat welding. PVC and its components are heat welded together. When supported by rigid coverboards plastics have greater hail resistant qualities. Both plastics (TPO & PVC) are manufactured in different membrane thicknesses.
