Preparation:
1. Install roof deck protection (i.e., underlayment),
such as GAF Deck-Armor
™
Premium Breathable
Roof Deck Protection, per manufacturer’s published
installation instructions. The roof deck protection
should always be installed leaving at least 6"
(152 mm) of exposed roof deck around the
plumbing pipe.
2. Cut a minimum 24" x 24" (610 mm x 610 mm)
square piece of self-adhering leak barrier, such
as GAF StormGuard
®
Film-Surfaced Leak Barrier,
and center the square over the top of the
plumbing pipe.
3. Cut an “X” in the leak barrier square from one
outside edge of the plumbing pipe to the other,
ensuring the “X” is slightly smaller than the pipe’s
overall width to allow the leak barrier to fit tightly
around the pipe.
4. Remove the release liner on the leak barrier and
lower the leak barrier down around the plumbing
pipe, firmly pressing it in place to the roof deck,
roof deck protection, and up the side of the
plumbing pipe itself. Reference (Figure 3)
for a sample of the completed preparation.
Note: A hand-held roller can be used to help ensure
maximum adhesion of the self-adhering leak barrier.
5. Proceed with shingling up to the plumbing
pipe, following the manufacturer’s published
installation instructions.
Pivot
™
Installation:
6. Separate the Pivot
™
cap assembly from its base
flashing assembly.
7. Using the base flashing’s built-in ball/socket pitch
adjustment feature, adjust the Pivot
™
so that it is
oriented vertically toward the sky. This feature
allows for simple rooftop pitch adjustment from
3:12 – 12:12.
8. With the “UP” arrow inscribed in the base flashing
pointing towards the roof peak, center and slide
the base flashing down over the plumbing pipe.
The bottom portion of the base flashing must
always sit on TOP of the shingle course below
the plumbing pipe. Use the Pivot
™
's rooftop pitch
adjustment feature to center the plumbing pipe in
the base flashing and to vertically orient the Pivot
™
towards the sky.
Note: For additional weather protection, a bead
of asphalt plastic roofing cement (ASTM D4585
Type I or Type II) or polyurethane roofing and flashing
sealant (ASTM C920) can be applied in a ‘U’ shape
pattern underneath the bottom and sides of the
base flashing (Figure 4).
