5.5.1 Allowable Design Pressure is the result of testing for wind load resistance based on allowable wind loads, and
reflects the ultimate passing pressure divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has already been
applied). Refer to FBC 1609 for determination of design wind loads.
5.6 Installation shall result in minimum net free ventilation area requirements set forth in FBC Sections 1203.2. When
more than one level of roof ridge existing over a single attic space, use ridge vents only at the high ridge.
6. INSTALLATION:
6.1 GAF Roof Ventilation Products shall be installed in accordance with GAF published installation requirements subject
to the Limitations set forth in Section 5 herein and the specifics noted below.
6.2 COBRA® EXHAUST VENT:
6.2.1 Chalk a cut-line 1-inch off each side of the ridge and cut a slot along the apex of the roof measuring 2-inch (for truss
construction) or 3½-inch (for ridge pole construction). The slot should terminate 6-inches from each end and 12-
inches from hip intersections or chimneys. Cut only the sheathing; do not cut trusses. Figure A.
6.2.2 Unroll the vent along the entire length of the ridge, covering uncut 6-inch sheathing area on both ends. Shorter
lengths can be joined by caulking and butting the ends. Figure B.
6.2.3 Apply a bead of polyurethane roof sealant to the underside of the entire perimeter of the vent and nail with min.
2½-inch galvanized roofing nails at each corner and 10-inch o.c.
6.2.4 Apply a bead of polyurethane roof sealant in the shape of a “C” to the underside of the entire perimeter of the cap
shingles, and install cap shingles directly over the vent using Smart Nails™ or 1¾-inch corrosion resistant coil nails
(supplied with the vent). Figure C.
6.2.5 Cobra® Exhaust Vent (hand nail version) and Cobra® Exhaust Vent (nail gun version) have a ¾-inch or 5/8-inch
nominal thickness, respectively, to facilitate ventilation. Care shall be taken not to crush or compact the product
during installation. Figure D.

6.3.1 Mark-off and cut the slot opening as follows, ensuring that the ends of the opening stop at least 6-inch from any
end walls and at least 12-inch from hip and ridge intersections or chimneys.
➢ No Ridge Board: Cut a 7/8-inch opening on each side of the ridge (Figure A).
➢ With Ridge Board: Cut a 1-5/8-inch opening on each side of the ridge (Figure B).
6.3.2 Sealant: Apply a bead of silicone caulking or roof cement to the underside of the outer baffle along both edges
and at exposed ends, ensuring the outside edges where the vent meets the shingles are sealed with the caulk or
flashing cement. Do not use excessive roof cement, as it may result in shingle blistering.
6.3.3 Vent Placement: Starting at one end of the slot, place, center and conform the Cobra® rigid vent over the slot
with the vent firmly against the roof surface, ensuring the vent extends past the slot opening by at least 6-inch.
6.3.4 Fasteners: For Cobra® Rigid Vent 3™, Cobra® Rigid Vent 3™ - 9”, Cobra® Snow Country Advanced™ and Cobra®
Snow Country Advanced™ - 9” only, use the 3-inch corrosion resistant ring shank nails (included). For Cobra®
Snow Country™, use corrosion resistant nails at least 3-inch or longer. Nails must always penetrate through
plywood decks or at least ¾-inch into wood planks. NOTE: GAF recommends 3-inch corrosion resistant ring shank
nails for increased uplift resistance.
6.3.5 Spacing: Attach the vent section through the pre-molded nailing holes located at 3, 12, 24, 36 and 45-inch from
the start of each 48-inch vent piece.
6.3.6 Joints: Apply the subsequent Cobra® rigid vent sections over the length of the ridge using the overlap/underlap
tabs.
6.3.7 Ridge Shingles: Install ridge shingles in accordance with shingle manufacturer’s published installation instructions,
using corrosion resistant nails detailed in 6.3.4. A nail line is inscribed on top of the Cobra® rigid vent to serve as a
guide.

6.4.1 Cut slot per 6.3.1.
6.4.2 Tear a 1-foot section to be used as a template for laying the vent out (Figure E-G) and center the template/ locator
over the ridge cap shingles at the beginning of the vent slot. Note the location of the baffle (Figure H). Make sure to
do this at both ends of the installation.
6.4.3 Measure the distance from the edge of the roof slot to the exterior baffle (D). Establish a chalk line along one side
of the ridge (Figure I). Unroll the vent and use the included 1-3/4-inch pneumatic corrosion resistant roofing nails
to attach the first side of the ridge vent with the exterior of the baffle aligned with the chalk line (Figure J). Proceed
with using the 1' interval EasyTear™ system to custom size the vent to the appropriate length. If the EasyTear™
system can not be utilized, use a utility knife to size the vent. Nail gun targets are embossed on the part as a guide
for property attaching vent to the roof. The vent should be fastened on 6-inch centers (Figure K).

6.4.4 For installations over extra-thick shingles, a bead of polyurethane roof sealant may be applied to the underside of
the outer baffle of the vent along both sides of the ridge and at exposed edges where the vent meets the shingles
to fill any open space between the vent and shingles below.
6.4.5 NOTE: When fastening the vent and cap shingles, be sure that the included 1 3/4-inch corrosion resistant coil nails
completely penetrate plywood or provide at least 3/4-inch penetration into wood planks. In the case they do not,
you must use alternate corrosion resistant nails that provide the required penetration. Proceed with attaching the
other side of the vent. When beginning to nail down the second side, do NOT begin at the end; begin between the
first and second one-foot sections and then return to fasten the first one-foot section. This will allow for proper fit.
6.4.6 Install ridge shingles in accordance with shingle manufacturer’s published installation instructions, using the nail-
lines on top of the ridge vent for proper lapping.
6.5 TRUSLATE® RIDGE VENT:
6.5.1 DO NOT use on hips.
6.5.2 Install TruSlate® Ridge Vent before installing the field slates.
6.5.3 After determining the total length of TruSlate® Ridge Vent required (for proper ventilation), determine the
necessary slot opening. Mark-off and cut the slot opening, ensuring the ends of the opening stop at least 6-inch
from any end walls and at least 12-inch from hip and ridge intersections or chimneys.
Roofs without a ridge board: Cut a 7/8-inch opening along the ridge on each side (Figure A).
Roofs with a ridge board: Cut a 1-5/8-inch opening along the ridge on each side (Figure B).
6.5.4 Install an 18-inch wide section of ASTM D1970 self-adhering leak barrier (holding Florida Statewide Product Approval
or Approved on a Local Basis) from the edge of the ridge slot extending down towards the roof deck on both side of
the slot.
6.5.5 Place the TruSlate® Ridge Vent over the ridge slot, “peaked” and centered over the ridge slot, and attach using
minimum 3-inch long corrosion resistant ring-shank nails through the pre-molded nail holes on the vent, located 3-
inch from the ends and 9-inch o.c. Fasteners shall penetrate through plywood decks or embed minimum ¾-inch
into wood plank decks.
6.5.6 Continue over the length of the ridge, utilizing the male/female connectors to connect units. Ensure the finished
ends include the pre-molded end caps. Cover all exposed nail heads on the vent with silicone caulk. Install a bead
of exterior grade silicone sealant at the downslope leading edges of the ridge vent, at the junction of the leading
edge and the leak-barrier below.
6.5.7 Install the top course of TruSlate® field slates, UnderBlock™ UV & Moisture Barrier and TruSlate® trim slates in
accordance with GAF published installation instructions. Install TruSlate® trim slates with 10-inch exposure using
minimum 1-5/8-inch long deck screws through pre-drilled holes, through the ridge vent to engage the wood deck.

6.6 COBRA® HIP VENT
6.6.1 The roof deck shall consist of minimum of 7/16 inch thick plywood or OSB wood structural panels. Use only on roofs
with slopes between 3:12 and 12:12. Install only on hips. Do not install Cobra® Hip Vent on ridges.
6.6.2 Sequencing: If ridge ventilation will be installed, always install the ridge vent to the end of the ridge before installing
Cobra® Hip Vent.
6.6.3 Hip Air Slot: Determine the number of Cobra® Hip Vent
sections needed for proper ventilation and the location
for cuts in the roof hip. Cobra® Hip Vent is installed over
a 2½ inch wide slot opening centered on the hip
beginning at 12 inches below the top of the hip and
extending 36 inches down the hip for every 4 foot
section of Cobra® Hip Vent needed. Leave 12 inches of
the hip uncut after each 36 inch opening, and the lowest
opening must stop at the mid-point of the hip and more
than 24 inches in from the exterior warm wall. Wider
openings and slots below the midpoint of the hip will not
improve ventilation and must be avoided. Cut away the
shingles first with a roofing knife, and then cut the deck
with a circular saw. The saw should be adjusted so that
the rafters or trusses are not cut. Note: The roof
decking must be re-nailed to the rafter at the edge
closest to the hip to compensate for the nails removed
when the hip slot was cut.
6.6.4 On plywood or OSB roof decks, where a sheathing seam intersects the hip air slot, stop cutting the air slot 2-inches
(51 mm) before the seam and continue cutting the slot 2-inches (51 mm) after the seam, leaving a total of 4-
inches (102 mm) of uncut deck at the seam. Then, proceed with cutting down to the previously marked 36-inch
(914 mm) point. The air slot may be widened, in this case, to 5/8-inch (16 mm) on each side of the hip rafter to
maintain proper NFVA.
6.6.5 Sealant: Seal all cut-edges of the asphalt shingles to the roof sheathing along all sides of the hip air slot openings,
using a bead of ASTM C920 polyurethane sealant, to prevent water infiltration.

6.6.6 Orientation: Always install Cobra® Hip Vent with the
“Towards Peak” arrows on the top surface of the vent
pointing up towards the peak of the roof.
6.6.7 Attachment: Cobra® Hip Vent is fastened to the deck starting at the bottom of the hip and then up along the entire
length of the hip (this includes un-cut portions of the hip). Fasten Cobra® Hip Vent to the deck with the included
1¾-inch inch long collated galvanized steel roofing nails, or longer corrosion resistant roofing fasteners, to achieve
penetration through plywood or OSB decks or minimum 3/4-inch embedment into wood planks. Attach the Cobra®
Hip Vent section through the pre-marked 6-inch increment nail targets.
6.6.8 Joints & Terminations: Apply the subsequent Cobra® Hip Vent sections over the length of the hip using the
overlap/underlap tabs. For roofs with ridge vents, lengths of the hip vent must be butted tightly to sections of ridge
vents and install a 3 inch by 12-inch strip of self-adhering leak barrier over all junctions. For roofs without ridge
vents, sections of hip vent from adjacent hip runs must be mitered together tightly where they intersect and install
a 3 inch by 12-inch strip of self-adhering leak barrier over all junctions. Refer to GAF published installation
instruction for details.
6.6.9 Ridge Shingles: Cobra® Hip Vent is then covered with ridge cap shingles and this entire assembly is nailed to the
sheathing with the included 1¾-inch inch long collated galvanized steel roofing nails. Depending on the field and
ridge cap shingles used, longer length corrosion resistant fasteners may be necessary. The ridge cap shingles are
installed per the shingle manufacturer’s instructions and Florida Product Approval, with a minimum of two nails per
shingle and a shingle to shingle nail spacing of 8 inches on center or less. Refer to the shingle manufacturer’s Florida
Product Approval for ridge cap shingle fastening and sealing requirements. Do not overdrive the nails or
crush/compact the product during installation.
6.7 COBRA® INTAKEPRO™ ROOFTOP INTAKE VENT
6.7.1 The roof deck shall consist of minimum of 7/16 inch thick plywood or OSB wood structural panels. Use only on roofs
with minimum slope of 4:12. Install only on eave edges of the roof.
6.7.2 Determine the length of Cobra® IntakePro™ Rooftop Intake Vent sections needed for proper ventilation and the
location for cuts near the roof eave edge. Install a metal drip edge at the eave of the roof. Measure up 6 and 7
inches up from the edge of the metal drip edge and strike chalk lines parallel to the eave of the roof. Cut a 1 inch
wide air slot opening along the chalk lines, stopping a minimum of 12" (305 mm) from rake/gable edges, side/end
walls, and hip intersections, and stopping a minimum of 24" (610 mm) from the center of valley intersections. The
saw should be adjusted so that the rafters or trusses are not cut.
Note: After cutting the air slot, clear all debris blocking access into the attic space. Be sure to flatten attic insulation
near the air slot to allow for proper intake airflow near the air slot. Attic baffles may be used to help prevent
insulation from blocking intake airflow into the attic space.
6.7.3 Install a minimum 18 inch (457mm) wide FBC Approved peel-and-stick leak barrier down to the roof deck. Align
peel-and-stick leak barrier flush to the edge of the roof on top of the drip edge metal. Use a sharp utility knife to
cut the leak barrier, re-opening the 1 inch (25 mm) air slot that was previously cut in the deck.

6.7.4 Each roll of Cobra® IntakePro™ Rooftop Intake Vent comes with two pieces of end cap fabric. To begin the vent run,
place one piece of end cap fabric overhanging halfway over the rake/gable edge and parallel to the eave drip edge.
Fasten the fabric to the roof deck using two roofing nails, one high and one low. If necessary, a piece of FBC
Approved peel-and-stick leak barrier can be used in lieu of end cap fabric.
6.7.5 With the pre-marked dotted nail line and GAF logo facing up toward the sky, position the vent on top of the fabric
end cap and flush to the rake/gable edge and eave drip edge. The front venting face of the vent should be flush
with the drip edge metal below. Using the included 1-3/4 inch (44 mm) pneumatic coil nails, fasten the vent every
6 inches (152 mm) along the pre-marked nail line and fasten every 12 inches (305 mm), approximately 1-1/2 inches
(38 mm) down from the up-slope edge of the vent. Do NOT nail within 1 inch (25 mm) from the side, top, or bottom
edges of the vent.
6.7.6 Continue installing vent toward the opposite gable/rake edge or termination point. When installing multiple rolls,
adjoin the rolls by butting them tightly together. There should be no gap between adjoining sections. The vent
must always extend a minimum of 12 inches (305 mm) past any air slots. Miter cut the vent at any valley and hip
intersections, ensuring the vent sections are butted tightly together. For terminations at gable and rake edges,
cover the end of the vent run using the included fabric end cap in the same manner as the start of the vent run.
6.7.7 Install FBC Approved peel-and-stick leak barrier completely covering the top of the vent and extending from the
eave edge to a minimum of 24 inches (610 mm) in from the building’s warm wall. The leak barrier should not
overhang the vent. Install rake drip edge if necessary.
6.7.8 Begin installing the shingle starter course. The starter course and first course of field shingles should overhang the
front edge of the Cobra® IntakePro™ Rooftop Intake Vent by 1/4 – 3/4 inches (6 – 19 mm) to provide a drip edge.
Using the included 1-3/4 inch (44 mm) pneumatic coil nails, fasten the starter strip and field shingles as per
manufacturer’s installation instructions. Ensure the field shingles are not fastened into the open air intake slot
below.
