The patented ‘Universal’ SmartVent End Cap can be installed Right Side or Left Side, as you begin your SmartVent run or end the run. Designed with the contractor in mind, this easy to install end cap makes working with SmartVent simple and cost effective. Use it to end a SmartVent run near a dormer, valley, hip, chimney or skylight.

Tapered End Caps

The SmartVent End Cap ‘tapers’ the SmartVent back down to the roof. All that you need to do is nail it down to the roof. Period! The fabric is already attached at the factory for right hand or left hand installations.



Tapered End Caps


Step 1– Ensure the 1” roof cutout was completed to 12” before the end of the run and the metal drip edge was previously installed. Nail the SV End Cap as shown with the bottom edge flush with the drip edge. Leave about 3” to 6” of roof deck showing from the wall. Nail at all four corners using nails that penetrate through the roof sheathing.

Step 3– Continue installing the remaining SmartVent over the roof deck sheathing and previously installed drip edge.

Step 4– Install 36” wide ice shield only over the SmartVent and SV End Cap tight against side wall and continuously across the roof. Keep 36” ice shield flush to the SV lift edge which will cover the entire top surface of the vent.

Step 5– Ensure the ice shield is only over the vent and tight against the wall for eave edge installations.

Step 6– Install wall step flashing over ice shield and up the wall. Allow a ½” to 1” eave edge overhang for shingles. Ensure step flashing is installed at each shingle course.

Step 7– Install starter course and shingles with a ½” to 1” overhang beyond the lift edge of the SmartVent. Ensure step flashing is installed at each course with the proper coverage.

Step 8– Continue installing tar paper and shingles up the roof with step flashing. The SV End Cap slopes the shingles down to the level of the wall flashing as shown.

Note: When using the SV End Cap on a mid-roof application, leave about a 12” space between hips and valleys so not to interfere with the flashing or cap shingles installation.

Using the SV End Cap should be easy and effective. Always ensure ice shield installs over the vent and carries at least 12” beyond the end when possible.
