liquid coating roof installation

Installation Description – 100% Silicone Roof Coating A 100% silicone roof coating system was installed over an existing roof in Los Altos Hills, California, with the primary goal of extending the roof's service life, protecting the existing surface, and enhancing its weather resistance. The project required special attention due to the presence of installed solar panels. Before applying the coating, the roof surface was carefully prepared to ensure proper system adhesion. Areas surrounding the solar panels, roof penetrations, seams, edges, and other critical points were treated with particular care to avoid disturbing the existing solar installation. The 100% liquid silicone system was applied uniformly over the prepared surface, forming a continuous, waterproof membrane that helps protect the roof against water and moisture penetration, as well as wear caused by constant sun exposure and temperature fluctuations. A key advantage of this system is that it allows for the restoration and life extension of an existing roof without the need for a complete replacement, thereby reducing the impact and costs associated with total reconstruction. Given the presence of solar panels, the work was executed carefully around existing structures, supports, and penetrations, preserving the integrity of both the waterproofing system and the solar installation.
