by cutting a slit 1” wide (or a series of 1 ¾” holes @ 3" center) into the roof decking 6” to

Be careful not to cut through the rafters!
NOTE: Ensure insulation is not blocking the flow of air extending to the roof ridge.
STEPS 2 & 3 protect the roof and attic from insects and wind driven rain.
Place the fabric piece half way on the roof side edge and even along the bottom of the drip edge. (Half of the fabric piece is hanging over the side edge of the roof.)
Nail the fabric piece(s) in place.
Lay the shingle length piece of SmartVent even with the drip edge and at the roof edges. Nail the SmartVent to the roof decking at the top edge. Wrap the end fabric so that it covers the outer edge of the SmartVent. Nail at the “nail line”. Nail every 12” along the nail line and matching nail at the top of the SmartVent.
Continue installing SmartVent until the last piece. Repeat STEPS 2 & 3 before laying the final SmartVent piece.
Install tar paper (or ice and water shield) “on top” of the SmartVent.
Shingle the roof as usual. You now have proper intake ventilation to your attic.
Note: Secure shingles to the roof deck at the ¾” lifted edge of the SmartVent with nails that penetrate through the roof sheathing. (Generally 1½” roofing nails are used on new roofs.)
