DCI Products SmartRidge I User Manual
SmartRidge I Directions
Before you start, decide which side the lift edge will be installed. To help with your
decision, the vent maximizes air flow dynamics and principles by placing the lift edge
on the leeward side of the ridge (downwind side). The vent works well with the lift
edge placed in either direction but it works ’best’ with the lift edge towards the
downwind side.
Note SmartRidge vents are designed to be installed on 4/12 and up roof pitches.
Low slope (below 4/12) roofs require additional work to prepare the roof for proper
installation. Contact DCI Products for low slope roof installation techniques and
special job specific instructions at 1-800-622-4455.
STEP Prepare Roof Decking
The first step installing SmartRidge I is to prepare the roof decking by cutting or leaving a
minimum 1” slit on both sides of the roof peak away from any ridge beam (do not cut at
least 12” in from the gable ends or other obstacles). A total maximum width of 3.5” is
required with or without a ridge beam. If wider ridge beams exist please call DCI with
specific details first. This is most easily done by cutting the last piece of roof decking 1.75”
short of the roof peak on both sides of the ridge leaving a 3.5” gap (see Fig A).
Note: The proper amount of soffit ventilation is required to maximize SmartRidge
effectiveness. Ask about our revolutionary soffit venting system called SmartVent.

STEP Attach SmartRidge I End Piece Patent # 6447392
After roof shingles are installed, begin at one end of the roof. In the SmartRidge I box are pieces of fabric (approx. 10 ½”
square) and four end caps that will be used to seal the gable ends. Install end caps as you start or stop a ridge run (or wrap
the fabric around the end of a piece) of SmartRidge I (your choice but the fabric is included if you need more than four end
caps).
Position the SmartRidge I three foot piece over the ridge so that it is nearly centered over the ridge opening. Butt the
SmartRidge I against the end cap (or if using the fabric pieces to seal the end, wrap the fabric tightly around the end of the
SmartRidge I piece ). Fold SmartRidge I over the ridge and secure to the roof decking/shingles using 1 ½” roofing nails
minimum (ensure nail goes through the roof decking). Ensure both long edges of SmartRidge I are tightly nailed to the
roof/shingles with no gaps between the vent and the roof. Use additional nails if necessary.
A nailing area on SmartRidge I is approximately 1.5" in from the edges of the product on either side with minimum six
nails per side equally spaced starting at the end and stopping at the opposite end 1.5” in from each end. This is
where you should nail when attaching SmartRidge I to the roof decking using 1 ½” – 2” roofing nails. Ensure nails
penetrate all the way through the roof decking. (SIX NAILS PER SIDE EVENLY SPACED
nailed tight against the roof with no gaps.
STEP Attach Remaining SmartRidge I Pieces
Attaching the next pieces of SmartRidge I can be done by butting the end of the next piece up tightly against the end of the
previously installed piece. Continue butting 3’ pieces of SmartRidge I until you reach the end of the roof. Cut the final piece to
fit flush with gable end cap and/or repeat step 2 to seal the end & install gable end fabric. Ensure both long edges are nailed
tight against the roof with no gaps.
STEP Install Cap Shingles
Install cap shingles over SmartRidge I as you normally would. Ensure that about ½” of the shingle cap extends past the lift
edge. Note: For aesthetic purposes, you can extend SmartRidge I all the way to the end of the gable roo f without
leaving it short of the gable end. SmartRidge I is strong enough to stand up to nail guns during shingle installation.
Use extra long roof nails (1 ½” to 2” nails) for securing the shingle caps. Shingle Cap Nails should penetrate through
vent and roof deck. Other installation techniques are available by calling DCI Products (engineering department).
