Sika - The Leading Resource for Adhered, Energy-Efficient Single-Ply Roofing Systems

Adhered roofing systems from Sika Roofing provide an aesthetically-pleasing roofing application that delivers superior, watertight protection — this protection is the result of time tested membranes, hot-air welded seams and a wide variety of system configurations to match the unique needs of individual building designs.

Leading the Way in Technology

Sika Roofing was the first single-ply company to develop a membrane specifically for adhered roofing applications. The Sarnafil G410 membrane has a non-woven fiberglass mat for superior dimensional stability and a low coefficient of thermal expansion and contraction — factors critical to the service life of an adhered roof. The G410 membrane has the best dimensional stability of any single-ply membrane, based on testing to ASTM D 1204.
