Please reference the drawing to the right
when reading these directions.
Step 1- Shingle up to the area that requires the
SmartVent.
Step 2- At the location of the shingle course
(where the SmartVent is to be located)
measure up from the bottom of the shingle
(the weather edge) 6” to 7” before
installing the actual shingle.
Step 3- Make lines at the 6” and 7” marks
and cut through the top of the previously
installed shingle and the plywood only.
Do not cut the rafters!
(or 1 ¾” holes @ 3” centers)
Step 4- Remove the plywood decking after the continuous cut and ensure the air flow is open from
the shed wall vent to the soffit area.
Step 5-Nail the SmartVent similar to the eave detail and make it even with the bottom edge of the
course of shingle next to be installed.
Step 6-Apply a roll of ice shield on top of the SmartVent even at the lower lift edge and directly to
the plywood above the vent. If tarpaper was already installed, gently tuck the ice shield under
the higher course of tarpaper so it laps over the ice shield by at least three inches or more.
Step 7-Install a starter course of shingle slightly overhanging the SmartVent bottom edge about 3/8”
to 1/2”. Align shingles per manufacturers’ directions.
Step 8-Install the shingles over the starter course as you would normally at the eaves edge and
continue up the roof. The installation at the mid-roof is very similar to that of the eaves edge.
If you have any questions or comments on installation please call 1-800-622-4455 and ask for
a roof ventilation technician to assist you.
Note: Stop any roof deck 1” cuts about 12” from rake edges, dormer walls or valley areas, or at ends
of the SmartVent runs, etc. Use the enclosed fabric at the open ends of SmartVent to seal for
weather and insects. Cut SmartVent even at the rake edges, miter SmartVent in the valley and
hip areas and return miter SmartVent to end at locations inside the roof edging. The ‘return
miter’ is available to see on our website or call to receive this installation detail.
(Pre-made factory SmartVent End Caps are available directly from our factory for ease of installation)
