GacoPatch is a flashing grade, standalone silicone roof patch designed to be installed in a single application without reinforcement. The convenient wide top pail makes GacoPatch application easy to do with a trowel or a brush. 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” thick.
GacoPatch is a silicone roof patch designed to provide a long lasting solution for a leaking roof. Use on cracks, expansion joints, flashings, gutters, penetrations, pipes, pitch pans, seams, small holes, transitions, vents and voids.
