Installation Instructions

STEP 1
Slot Preperation
Determine amount of ventilation required and length of slot. Cut a horizontal 3⁄4”
slot in the deck, leaving a minimum of 6” uncut on each end of the slot. Install
underlayment and shingles per manufacturer’s instructions. Do not cover pre-cut slot.
STEP 2
End Cap Installation
Cut a slit in the StormStop membrane 1⁄2” by the thick part of vent. Place sealant
on both sides of membrane. Insert foam end cap with the thickest side positioned
near the air intake and tapered side up the deck where the vent is nailed to the roof
deck. Membrane should be touching the plastic part of vent and end cap should be
touching roof. An end cap must be placed at the beginning and end of each section.
STEP 3
Multi Roll
®
Multi-Purpose Vent Installation
Lay a bead of sealant 3” below the cut slot. Place front edge of vent 4” below the
pre-cut slot. Unfold the membrane and pull straight. Place a bead of sealant 4-1⁄2”
above slot underneath membrane. Nail membrane and plastic to roof deck. All nails
must penetrate the roof deck at least 3⁄4”. Nail down the bottom lead edge of vent
and in the middle through the end cap. Roll out vent and pull tight; nail at 10’ and
again at the end of the roll.
STEP 4
Finishing Shingle Installation
Install ice & water barrier and shingles on top of vent, treating the thick edge of the
vent as a starter course. Install shingles per manufacturer’s instructions.
