Round Base Retrofit Flashing - Gray EPDM

The Universal Retrofit has been designed to accommodate existing applications where a standard pull over flashing cannot be installed. The split design allows an easy wrap around fit with a single stainless steel clamp for sealing.

  • simple solution to flashing a penetration through a metal roof that requires a wrap-around installation
  • wraps easily around existing or hard to reach penetrations
  • has clearly marked diameters on each flashing
  • marked dimensions also allow for easy sizing to fit each individual application
  • snaps together in seconds and does not require any special tools or accessories
  • resistant to ultraviolet rays, cracking & weathering.
  • the aluminum base on the upper lip is corrosion resistant and allows the flashing to conform to any panel configuration and/or roof pitch.

    1. Begin cutting opposite of the mechanical locking joiner. Cut through the joiner with tin snips
    2. Wrap the flashing around the pipe. Engage the top section of the joiner first, then proceed down until the joiner is completely engaged.
    3. Crimp joiner tightly, starting at the top by squeezing the joiner "fingers" with pliers.
    4. Apply sealant to the underside of the ribbed aluminum base. Press the pipe boot against contours of the panel configuration.
    5. Attach the flashing to the panel with self-drilling screws. Screws should be spaced as necessary to avoid gaps between the base and the panel.
    6. Apply additional sealant around the top of the pipe boot & along the mechanical joiner seam.
