GacoPatch is a flashing grade, standalone roof patch made with 100% silicone. 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, seam tapes or top coats.

New and improved technology allows for GacoPatch to be the long-term solution for roof repairs. It does not contain asphalts or acrylics and is extremely durable. GacoPatch remains permanently flexible even under permanent ponding water. It is UV stable and will not chalk, crack or peel.

No reinforcements or extra steps are required for horizontal patches, even over 1/2" thick, because GacoPatch resists degradation over time and will not become brittle or break down. Use GacoPatch when you need your patch to be permanent.

GacoPatch is a silicone roof patch designed to provide a long-lasting solution for a leaking roof.
