Self-adhesive roof flashing seals roof penetrations (pipes, vents, conduit) and transitions (roof-to-wall) by bonding directly to the roofing surface. It is particularly useful for irregular penetrations that rigid boot-style flashings cannot seal.

Yes. Dektite Fast Flash polymer flashing bonds to metal roofing surfaces and remains flexible enough to conform to corrugated and ribbed metal profiles. Clean the metal surface thoroughly before application for best adhesion.

Dektite Fast Flash adhesive roof flashing is available in 11x16 ft (176 sq ft) and 22x16 ft (352 sq ft) rolls, allowing you to cut custom flashing shapes for any size penetration or transition.

Clean and dry the roofing surface thoroughly. Peel back the release liner from the adhesive backing. Press the flashing firmly against the surface starting at the center and working outward, ensuring full contact with no air pockets or wrinkles.

Adhesive performance is reduced in cold weather (below 40 degrees F). If application in cold conditions is necessary, store the roll in a warm location before use and apply when the surface temperature is above 40 degrees if possible.

Yes. The polymer material in Dektite Fast Flash is UV stabilized and resists deterioration from sun exposure, maintaining its flexibility and adhesion over the long term.

Yes. Most compatible exterior paints can be applied over Dektite Fast Flash once it is fully adhered. Check the Dektite product specification for paint compatibility if using a specialized coating.

Dektite Fast Flash is a self-adhesive sheet flashing for custom shapes and irregular penetrations. Dektite pipe boots are pre-formed boot-style flashings for round pipe penetrations. Both are Dektite products but serve different flashing applications.

Dektite self-adhesive polymer flashing is designed for long-term outdoor use and resists weathering, UV, and temperature cycling. Inspect annually and repair any lifted edges with compatible roofing sealant.

Once fully adhered, self-adhesive roof flashing is difficult to remove without damaging the underlying surface. Plan your placement carefully before removing the release liner and pressing the flashing into position.
