HIGHPOINT™ INVISARIDGE™ EXHAUST VENT
INSTALLATION INSTRUCTIONS
1
Remove ridge cap shingles from the
entire length of the ridge.
Note: Delete Step 1 for new
construction.
4
For appearance (to blend with the roof
line), it is recommended that the
HighPoint™ vent be installed the
entire length of the ridge. Position the
rst piece at one end of the ridge.
Using 2-1/2" nails, for 3/4" deck
penetration or penetration through the
deck, which ever is less, anchor vent
through preformed nail holes.
7
Ridge-to-ridge application requires a
mitre-cut to maintain continuous
ridge line appearance.
• YOU MUST HAVE A BALANCED VENTILATION SYSTEM!
• SOFFIT INTAKE SHOULD EQUAL RIDGE EXHAUST.
Ventilation Requirements
Inadequate ventilation of attic areas can cause a build up of moisture and heat. These
conditions can cause:
1. Accelerated roof weathering
2. Deck rot and attic fungus
3. Shingle distortion due to deck movement
4. Blisters
Install roof vents at ridges and eaves. FHA requires one square foot (0.1 sq. m) of free
ventilation to each 150 square feet (13.9 sq. m) of attic area or one square foot (0.1 sq.
m)/300 square feet (28 sq. m) if 50% ventilation is provided near the ridge.
UNIFORM BUILDING CODES
R806.2 Minimum area. The total net free ventilating area shall not be less than 1/150 of the area of the space
ventilated except that the total area is permitted to be reduced to 1/300, provided at least 40 percent and not
more than 50 percent of the required ventilating area is provided by ventilators located in the upper portion
of the attic or rafter space. Upper ventilators shall be located not more than 3 feet (914 mm) below the ridge
or highest point of space, measured vertically, with the balance of the required ventilation provided by the
eave or cornice vents. See the published International Residential Code for additional information.
• HIGHPOINT™ EXHAUST VENTS are designed for varying roof pitches (3/12 through 16/12).
• For safety, always wear safety glasses.
• Application and installation procedures are beyond the control of the seller or manufacturer.
(Consequently, neither party shall be responsible for failure of the product when not used in strict
accordance to instructions and speci cations.)
2
Snap chalk line on both sides of the
ridge and no more than .750 (3/4) of an
inch from the peak. Note: If a ridgepole
is present, cut a wider gap to allow a
minimum of 1/2" air gap on both sides
of the pole into the attic space - but do
not remove more than 2-1/4" of roof
sheathing material from either side of
the ridge. Refer to ridgepole diagram.
5
Nail each additional section in the
same manner until entire ridge is
covered. A chalk line may be utilized
to ensure vent alignment. Cut last
piece to length and install with
original uncut end to the outside.
8
Optional
Ridge-to-roof application requires a
mitre-cut to maintain continuous
ridge line appearance.
3
Cut along chalk lines. Remove roof
sheathing. Note: Slot should not be
cut any closer than within twelve (12)
inches of gable end, hip intersecting
ridge.
6
Install new ridge cap in normal
manner, using 2-1/2" roo ng nails, for
3/4" deck penetration or penetration
through the deck, whichever is less.
Nailing the ridge caps through the
vent along the nailing line will secure
the vent. Shingles may need to be
trimmed.
