Liquid Roof Membrane
A liquid-applied roof membrane rebuilds the waterproof layer of an aging roof without tearing it off. The system rolls or sprays on as a single, seamless skin, then cures into a fabric-reinforced membrane warranted for 10, 15, or 20 years.
Coatings Supply carries the GAF Premium Acrylic HydroStop system, the standard for fully-reinforced liquid membranes (Base Coat, fabric, Top Coat, Premium Acrylic Flashing), Miami-Dade NOA 21-0105.10 approved for HVHZ projects. For roofs with ponding-water conditions, GAF High Solids Silicone is the warranted alternative. Each system pairs with the right GAF primer for the substrate (Multi-Purpose, Metal Roof, Bonding, Epoxy, Bleed-Block, TPO Red) so the spec stack ships complete.
Factory-direct from a GAF-authorized distributor, with technical support on substrate-to-primer matching.
