Liberty™ SBS Self-Adhering Roofing System

Protect Your Property From Fire Dangers And Fumes By Installing A Self-Adhering Roofing System

A Self-Adhering Roofing System will provide long-lasting protection for the low slope areas of your property without the danger or hassles associated with the installation of other conventional roofing products.

Liberty™ systems are applied without torches, open flames, hot asphalt, or messy solvent-based adhesives. Unlike traditional roofing systems, they can be installed easily and quickly by a small roofing crew, without the hassles of bulky equipment or unpleasant odors.

Liberty™ self-adhering roofing systems are a key part of the GAF-Elk Smart Choice® Roof System Solution
