STEP 5
Install ice and water shield (or tar paper in warm climates)
“on top” of the SmartVent. Standard building code
requirements determine when ice shield should be used. Full
width ice and water membrane (36”) is required to be
installed over the SmartVent in all snow environments.
Ensure the upper underlayments are lapped over the lower
underlayments. Any questions please call the DCI Technical
Department.
STEP 6
Shingle the roof as usual. You now have proper intake
ventilation to your attic.
NOTE
edge of the SmartVent with nails that penetrate through the
roof sheathing. (Generally 1½” roofing nails are used on new
roofs.) Shingles must overhang the SmartVent lifted edge by
3/8” minimum to 1” maximum. Refer to shingle
manufacturer application manual. Any questions please call
DCI Technical Department.
: Secure shingles to the roof deck at the ¾” lifted
NOTE: SmartVent can be installed under virtually any shingle course using proper installation
techniques. SmartVent should be installed on shingled roofs with a minimum of 4/12 pitch.
There is no maximum slope limitation. Low slope roofs with less than 4/12 pitch can use
FasciaVent by DCI for intake ventilation. Use of continuous ridge vents and other exhaust vents
are required. No moisture from household appliances, equipment or fixtures can be discharged
into the attic area. Maximum rafter length is 22 feet to maintain proper NFA(soffit to ridge).
