INSTALLATION / HOW TO INSTALL
RETRO PIPE FLASHING
-
Lift
or remove the roof tiles which will overlap top of metal flashing.
-
Clean
area as needed to assure good sealant adhesion.
-
Apply
M1 sealant or
butyl
sealant under the metal flashing base.
-
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.
-
Seal
the "door" edges with M1 sealant, or solder closed.
-
Open and wrap both EPDM Retro-collar pieces around the pipe (upper
collar and also the skirt).
-
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.
-
Attach the metal clamp and tighten. Inspect to see that there is no
gap in the top-collar.
-
Trim
shingles. Apply M1 sealant and re-attach shingles along the top area. Seal again at
the shingle perimeter with M1 sealant.
