Installation of Metal Base or Super Neo-Poly™ Roof Flashings
Aluminum, Galvanized, Copper Neva-Calks™, Multi-Fit™ and Super Neo-Poly™
Flashings
Make sure the roof is clean and has no protrusions before installing the roof
flashing:
Inspect vent pipe to make certain there are no sharp edges on the rim of the
pipe that could damage, split or tear the collar and the pipe is free of any
grooves or ridges. Extreme grooves or ridges should be smoothed with coarse sand
paper to ensure proper sealing. Pipe sizes are indicated on the collar. Make
sure that the collar size indicated matches the pipe inside diameter (i.e. 1.5”
flashing for 1.5” pipe, 2” flashing for 2” pipe size, etc). Overstressing the
collar may result in premature failure. Multi-Fit Flashings have the appropriate
pipe size molded on the collar. If removal of a ring(s) is required to correctly
size the collar, use a sharp tool such as a screwdriver between the double
grooves to pierce and remove the excess ring(s). Place the proper size flashing
over the vent pipe with the long side of the base on the upside of the roof. We
are changing the collar to an improved, softer elastomer. Because of this, we
recommend that you visually align the base to generally conform to the roof
pitch when the flashing is placed over the pipe before pushing the flashing down
to contact the roof. This will assure there will be no dimpling or coupling of
the softer collar and will give a better appearance to the installation.
Use corrosion resistant nails or staples to secure the up or
high side of the flashing to the roof. Nail or staple all corners and along the
sides at intervals of 4”-6” to secure the flashing. The top of the flashing will
be covered one-quarter to one-half of the way down with roof shingles. The
bottom edge of the flashing should overlap the shingles beneath it so that it
sheds, not traps, water.
It is recommended that exposed nails or staples be covered with a silicone
sealant, which also may be applied to the underside of the base to improve
sealing capability.
Important: Petroleum based sealants or cement products may be used on metal
bases of flashings only. Never use petroleum base adhesives, sealing
compounds, solvents or paints on all flashing collars or on the Super Neo-Poly™
base.
