GacoPatch is a flashing grade, stand-alone silicone roof sealant designed to be installed in a single application on a variety of roof types including asphalt, single ply, metal, and most existing coatings. GacoPatch 2 gallon pails are available in White, Gray, Black and Tan. It is a one-step application which reduces labor time and 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 ½” thick.
