INSTALLATION: 6. 1 GAF-ELK Roof Ventilation Products shall be installed in accordance with GAF-ELK published installation requirements subject to the Limitations set forth in Section 5 herein and the specifics noted below. COBRA® EXHAUST VENT: Chalk a cut-line 1-inch off each side of the ridge and cut a slot along the apex of the roof measuring 2-inch (for truss construction) or 3½-inch (for ridge pole construction). The slot should terminate 6-inches from each end and 12-inches from hip intersections or chimneys. Cut only the sheathing; do not cut trusses. Unroll the vent along the entire length of the ridge, covering uncut 6-inch sheathing area on both ends. Shorter lengths can be joined by caulking and butting the ends. Apply a bead of polyurethane roof sealant to the underside of the entire perimeter of the vent and nail with min. 2½-inch galvanized roofing nails at each corner and 10" o. c. Do not use excessive roof cement, as it may result in shingle blistering. Apply a bead of polyurethane roof sealant in the shape of a "C" to the underside of the entire perimeter of the cap shingles, and install cap shingles directly over the vent using Smart NailsTM (supplied with the vent). Do not use excessive roof cement, as it may result in shingle blistering. 6. 2 6. 2. 1 6. 2. 2 6. 2. 3 6. 2. 4 Exterior Research and Design, LLC.
