Commercial Roofing - SBS (Two-Ply)

A torch on roof, or as it is commonly known a 2-ply SBS roof system, is rapidly becoming the most popular roofing system in the market today. Actually consisting of polyester or fiberglass reinforcing mat sandwiched between two layers of rubberized asphalt, two ply roof system are durable and quick to install. Installers who attempt to install torched on roofing without proper training (apprenticeship/journeymanship) generally show their lack of experience in the work that they do. An improperly installed torch on roof will likely fail within the first two years of use. Applicator quality is one of the only sure ways to eliminate costly replacement. Parker Johnston Industries Ltd. guarantees our two ply SBS roof systems for 10 years against defects in workmanship, assuring the customer that the roof will be there for the long haul. The quality of different two ply SBS systems varies and unlike some items, cost is not always the best measure of performance.
