The high adhesion alternative to replacing your weathered roof.

GacoFlex S42 Series is a 100% silicone roof coating that renews weathered roofs. This high-adhesion coating installs over almost any existing roof substrate. It creates a durable, seamless membrane that protects against ponding water, UV light, and severe weather.

GacoFlex S42 Series covers more area with less material than many competing silicones. It delivers excellent peak hide coverage on granulated surfaces. With strong adhesion to multiple substrates, it often eliminates the need for an epoxy primer. As a result, crews complete installation faster.
