Single Ply Roofing

EPT pioneered the development and production of modified PVC single-ply roofing membranes, incorporating DuPont Elvaloy®/KEE, a unique plasticizer that keeps the material indefinitely flexible, while making it highly resistant to environmental and temperature extremes and exposure to a wide range of chemicals and pollutants. They are ideal for mechanically attached, fully-adhered, ballasted and green roof applications. 


Since 1990, our sister company Flex Membrane has been providing architects, contractors and specifiers the highest quality in complete roofing systems for commercial, industrial, institutional and residential structures.
