SBS Roofing Systems

SBS (Butadiene Styrene) roofing systems are applied in multiple layers. The top surface is a mineral granular with a choice of colors. It has the benefits of a built-up redundant system with the quality of a factory single ply membrane.

APP Roofing Systems

APP (Atactic Polypropylene) roofing systems are applied in multiple layers, with the top surface in either smooth or granular. The consistency and uniformity of the factory produced sheet results in membrane that has greater stability and flexibility than that of a laminated built-up roof system.
