I have been a roofing contractor and general builder for over 15 years. In that time I have had extensive experience in laying different types and makes of roofing membranes including torch on felt and pvc systems. In my opinion Firestone Rubber Cover EPDM roofing systems is the best system available on the market. I can cover many small residential roofs in one piece of rubber. With the extremely long life expectancy my clients do not have to worry about replacing their roofs in the future. The technical assistance and support which I receive from QBM is one of the many reasons why I would recommend using Firestone EPDM Rubber Cover to waterproof any flat roof.
