1. Hip and Ridge Ventilation Slot Preparation
Determine how long of a hip and ridge ventilation slot will be required
according to 1:300 rule. The ridge and hip ventilation slot may be pre-cut on
a new roof before or after shingle installation or in a retrofit, the slot can be
cut from the pre-shingled roof using a circular saw with a carbide tip blade
(protective eye goggles should be worn during this process). Start ridge
ventilation slot 6” from point where hip and ridge meet. For
5
⁄
8
” profile vents,
cut a 2” slot (1” on each side of ridge) along the ridge(s). For a roof with a
center beam, a 3
1
⁄
2
” slot should be cut (1
3
⁄
4
” on each side of ridge). For 1” profile
vents, cut a 2
1
⁄
2
” slot (1
1
⁄
4
” on each side of ridge). For center beam applications
a 4” slot should be cut (2” on each side of ridge). If entire ridge requires
ventilation, stop ventilation slot 6” from point where hip and ridge meet. To
maintain structural integrity, one continuous slot is not recommended on
hip applications. Start ventilation preparation by leaving 6” of hip uncut
from where the ridge and hip meet. Cut a 3
1
⁄
2
” wide slot for ventilation. Hip
slot should be 18” in length, spaced with a 12” uncut area between each 18”
opening. The slot for ventilation should not be cut any lower than the top
1
⁄
3
of the roof to maintain a balanced ventilation system.
2. End Cap Installation
Pull apart a pre-cut section of the foam end cap found with the vent. Using
a utility knife, make a cut in the StormStop material
1
⁄
2
” on each side, back
from the end of the section. Using construction adhesive or sealant caulk,
coat both sides of the StormStop material where it has been cut back at
the end of the vent. Insert the foam end cap with the cut-back StormStop
material between the foam end cap and the underside of the vent to
assure a weather-tight seal. Because of the popularity of dimensional
roofing material such as 40/50 year and lifetime laminated shingles
we require that a bead of sealant be applied to the roof shingles before
installing the vent on the ridge. This sealant should fill any voids between the
bottom of the vent and the surface of the shingle. Use either butyl sealant
conforming to ASTM C1085, latex sealant conforming to ASTM C834, silicon
sealant complying with ASTM C 920 or asphalt roofing cement complying
with ASTM D4586.
3. Vent Placement on Ridge
Attach vent to the roof deck by driving a nail in each of the two corners
on both ends of the vent. Also, drive two nails through the vent and
foam end cap to hold foam in place on the ends of the ridge only.
Nails should penetrasor to cap shingle installation. Because of the
popularity of dimensional roofing material such as the newer 40/50 year
and lifetime laminated shingles we require that a bead of sealant be applied
to the roof shingles, before installing the vent on the ridge. See step 2 for
recommended sealants.
