As self-adhering flashing tape, it is primarily used to seal roof seams, joints, and nail penetrations before the installation of shingles or underlayment. This ensures enhanced protection from water, wind-driven rain, and air infiltration, effectively reducing the risk of leaks and subsequent costly repairs.The tape is made from advanced polymer materials, offering strong adhesion to most roof deck substrates, including plywood, OSB, and metal. It remains flexible over a wide range of temperatures, making installation easy regardless of seasonal climate conditions.
