Installation Instructions

IMPORTANT NOTES BEFORE INSTALLING:
1. When using architectural shingles, seal the gap between the vent and shingles making sure not to plug drain holes. Caulk is not needed
with 3-tab shingles.
2. Make sure the filter (if supplied) is centered in the ridge vent and pinched to the shingles prior to cap nailing, leaving no gaps.
3. When installing the ridge vent in cold weather, leave a 1/8” gap between ridge vent ends to allow for expansion in hot weather.
4. See instructions below for cutting slot.
5. Run the ridge vent from end to end on the roof for a more even, attractive appearance.
6. Carefully place the ridge vent prior to cap shingle nailing with the preformed nail holes provided in the vent. Overnailing will cause the vent
to buckle. Undernailing could allow the nails to back out of the deck.
7. All nails must penetrate the underside of the roof deck. Verify adequate nail length prior to installation.
STEP 3.
On existing roofs, remove cap shingles. Mark
slot width at both ends of ridge. Use slot guides
imprinted on vent and refer to drawings below.
Snap chalk line on both sides of ridge.
Hip and Gable Roofs
Cut slot 3/4” on both sides of ridge centerline
or from ridge board and to within 6” of end
wall or hip intersection as illustrated in
Figure 4.
Cut slot (plumb cut, if possible). Note: Adjust depth
of blade to avoid cutting rafters or trusses. Refer to
drawings below for slot dimensions.
Remove debris from slot.
Use utility knife to cut final section to length. Final
section should be oriented so the built-in ventilating
end plug is exposed. For ridge lengths shorter than
the product, cut product to length. Then cut at near-
est, correctly oriented, end plug. Reverse this short
section to have end plug flush with end of roof.
“L” and “T” Shaped Roofs
Cut slot as per Figure 5 and run Ridge Vent
across long ridge. On short ridge, cut slot to within
12” of junction point and run Ridge Vent from
end of roof to butt against crossing Ridge Vent.
Roll out and center vent over slot. End should be flush
with end of roof. Make sure vent’s support walls sit
flat on the roof, and that filter for Peak Performer™ II
is secure between shingles and vent.
Nail cap shingles in place using roofing
nails long enough to penetrate roof sheathing.
Use nailing lines provided on vent as guide.
If using a nail gun, refer to #6 & 7 under
important notes.
Chimneys
Cut slots to within 12” of chimney. Run
Ridge Vent from end of roof to butt
against chimney as shown in Figure 6.
