INSTALLATION / HOW TO INSTALL RETRO PIPE FLASHING
  1. Lift or remove the roof tiles which will overlap top of metal flashing.
  2. Clean area as needed to assure good sealant adhesion.
  3. Apply M1 sealant or butyl sealant under the metal flashing base.
  4. Slip on the metal retro-spin flashing base. Close the base around pipe so that the "door" faces downhill. Be sure M1 sealant creates a seal to the underlayment. Nail flashing along upper area. Add an additional bead of M1 at the metal edge and over nail tops.
  5. Seal the "door" edges with M1 sealant, or solder closed.
  6. Open and wrap both EPDM Retro-collar pieces around the pipe (upper collar and also the skirt).
  7. Push the both the top collar and skirt units together (they interlock like a puzzle and have an internal sealing lip). Add a bead of M1 at the top collar mate point as needed.
  8. Attach the metal clamp and tighten. Inspect to see that there is no gap in the top-collar.
  9. Trim shingles. Apply M1 sealant and re-attach shingles along the top area. Seal again at the shingle perimeter with M1 sealant.
