Vent/Pipe Flashing Installation Procedure
STEP 1: Cut
Cut to pipe diameter marked on
Flashers (this is approximately
20% smaller than the diameter of
the pipe).
STEP 2: Slide
Slide the Flashers down the
pipe, using water to lubricate
if necessary.
STEP 4: Seal
Seal the Flashers by applying
urethane/silicone sealant between
the Flasher and the roof. Use a
large slot screwdriver to press the
base down tightly.
STEP 5: Fasten
Fasten the Flashers with weather-
resistant fasteners to complete the
seal.
STEP 3: Form
Form and bend the aluminum base
of the Flashers to fit the surface of
the roof.
Note: For the best drainage when a square-based
pipe flashing is used, one corner of the flexible pipe
flashing should be oriented to the high-side of the roof.
