professional, and to check with your local building inspector or building permit office for approvals and possible variations that may apply.

When working with power tools and sheet metal, gloves and eye protection are absolutely required.

OFF RIDGE VENT
Weather Vent™ has a screened external wind baffle to provide superior air flow with maximum weather protec-
tion. Used in conjunction with gable and/or soffit vents, this system provides an effective natural air flow. Self
flashing flanges allow for easy installation.
Cut Opening
The Weather Vent™ should always be installed in combination with a
balanced soffit vent system. Vent should be installed on one side of
the ridge of an open attic. Note: If adding vents to existing roof,
remove tiles in that area that the vent is to be located.
With a circular saw cut opening in the roof sheathing. Locate the top
of the opening minimum of 6 inches off the roof edge.
For shingle vent applications install vent at the center of the roof
length. Multiple vents should be evenly spaced along the roof length.
Place Vent
Apply a bead of roofing cement around entire perimeter where
flange will fall. Position the vent over the opening in the roof
sheathing. Make sure the vent covers the opening completely
without interfering with airflow and is lined up with the last
course of shingles.
Seal
Attach the vent with #9 x 1-1/2 in. (min.) HWH screws with 0.5-inch
sealing washers or 12 ga. x 1-1/4 in. (min.) ring shake nails with
min. 3/8 inch diameter heads, having sufficient length to penetrate
through the sheathing a minimum of 3/8 inch. The fasteners shall
be located 1 inch from the edge of the flange and 5-1/2 inches o.c.
along all four sides of the vent. When nails are used to attach the
vent, all penetrations through the vent flange shall be sealed using
ASTM D 4586 or ASTM D 3409, Type 1 roofing cement.
