Note: Roll Vent will only vent 9 sq. in. per linear foot in this application. The Venturi effect will be limited.

Start Roll Vent a minimum of 1" from each end of roof using the end cap installation (pg 2). Center ridge cap shingles over vent and install with nails provided. Use nail line as placement guide. Nails must penetrate into the sheathing 3/4" or completely through the sheathing. Ridge cap shingles must overhang Roll Vent by 1"minimum at each end of roof.

For added weather protection, install counter flashing behind siding and over top of cap shingle.
