How To Install

Watch Installation Video

Step 1

Determine how much additional ventilation is required and the best location for the holes.

Step 2

Shingle courses should be installed close to the deck opening so that the front flange of the vent completely covers exposed section of shingle.

Step 3

Position the vent to cover the last course of shingles at the sides and bottom of the opening. Center the vent over the opening in the deck. Apply an industry approved sealant under front flange of vent.

Step 4

Fasten side and top flanges securely with minimum 1.25” standard roofing nails spaced 4” on center and 1.5” from outer edge of flange.

Step 5

Apply roof cement on side and top flanges. Completely cover flanges 2” beyond flange onto underlayment with ¼” thick bed of plastic roof cement or equal.

Step 6

Install shingles, cut to fit so flanges are completely covered. Press into place to ensure a complete bond of cement to the shingles. Fasten shingles with nails as per shingle manufacturer’s instructions.

Tip: Pre-cut shingles to fit prior to applying roof cement. Then remove cut pieces, apply roof cement, and install shingles per above.
