Rubberized-Torch System
Polyester reinforced APP membranes are designed for direct flame heat welded applications. Commonly known as “Torch” roofing systems, they are liked by many roofing professionals for their straight forward application and ease of installation. These roof systems achieve a water tight seal by applying a direct flame onto the roof membrane and melting a bituminous layer that is embedded within the roll itself; thus creating a waterproof seal.
PROS: Easy installation, less equipment and labor, flexible, no tar smells.
CONS: Fire hazard due to use of a direct flame on the roof, very easy to install incorrectly.
