EPDM Roofing

EPDM is a synthetic rubber that is also a very good choice for commercial flat roofs. EPDM is a flexible membrane that has been in use since the 1960’s and has survived some of the world’s toughest climates for over 30 years. Though it was a good product to begin with, EPDM has advanced significantly in the last ten years. Problems previously associated with it included moisture gain under the membrane and that EPDM did not like to adhere to itself causing seam problems. Using a vapor barrier has solved the moisture gain problems and seaming has become extremely simple with the addition of factory applied tape. This has greatly reduced labor costs and installation time. The addition of factory applied tape also makes for stronger and neater seams.

When installing EPDM, Old Pro Roofing uses two different methods. Mechanically attached is a less expensive method and has been proven to work well in areas with low wind velocity. Fully adhered is the most expensive installation method but will also guarantee a stronger and longer lasting flat roof.

The latest products of EPDM have been combined with a polyester fleece backing and fabricated with a patented hot melt adhesive technology. This provides consistent bond strength between the fleece backing and the membrane and has resulted in largely eliminating shrinkage of the product. It also allows the product to stretch to three times its normal size and move with the building through changing weather conditions.

When properly installed, EPDM flat roofing has been proven to last from 25-50 years and this continues to rise every year with advances in technology. Old Pro Roofing has extensive expertise installing EPDM roofing membranes and can help you with all of your commercial roofing needs.
