Gaco Patch Silicone Roof Patch 2 gal. (White)

Gaco Patch is a premium, flashing-grade silicone roof patch formulated for fast, one-step repairs. This 2-gallon white formula adheres directly to most roofing substrates—no primer, reinforcement or topcoat needed. Designed to remain permanently flexible, Gaco Patch resists UV exposure, ponding water and temperature extremes without cracking, chalking or becoming brittle. Whether you’re sealing leaks around vents, skylights or roof penetrations, this self-curing silicone delivers a long-term solution in a single application.
