Flashing tape is a self-adhering tape used to seal and protect vulnerable joints, seams, and openings. It is often used around windows, doors, penetrations, and wall transitions.
Why It Matters
Water often finds weak points at openings and transitions. Flashing tape can help direct water outward when it is installed in the correct sequence with house wrap, flashing, trim, and siding.
Common Problems
Problems include reverse laps, dirty surfaces, poor adhesion, wrinkles, missing corner protection, and tape used as a patch instead of part of a planned flashing system.
Building Codes & Industry Standards
Flashing tape should be compatible with the surrounding materials and installed according to product instructions. Window, door, and wall assemblies often depend on proper sequencing.
Exterior Echelon Notes
Exterior Echelon pays attention to flashing tape around openings because small mistakes at transitions can lead to hidden water problems later.
