GacoPatch is a flashing grade, standalone silicone roof patch designed to be installed in a single application without reinforcement. GacoPatch is a one-step application which eliminates the cost of additional products such as primers, tapes and top coats. GacoPatch is a long-term solution for roof repairs because it is UV stable and does not chalk, crack, become brittle or break down over time. GacoPatch contains no asphalts or acrylics, and remains permanently flexible, even under ponding water. No additional reinforcement or extra application steps are required for horizontal patches, even over 1/2 In. thick.
