20'x10.5" Cobra Roof Vent Roll by GAF, Nail-Gunnable for excess moisture and heat exhaust

GAF Cobra Exhaust Vent for Roof Ridge – 20' x 10.5", Nail-Gunnable

GAF Cobra® Exhaust Vent for Roof Ridge is a shingle-over ridge vent designed to remove excess heat and moisture from attic spaces. The vent allows warm, moist air to escape at the roof ridge while fresh air enters through intake vents near the soffit. This balanced attic ventilation helps reduce excessive attic heat, moisture, condensation, and the risk of winter ice dams.

The 20-foot nail-gunnable version has a 10.5-inch width for use with 12-inch ridge cap shingles. It has 14.1 square inches of net free ventilating area per linear foot and includes 1-3/4-inch corrosion-resistant coil nails. The flexible roll design supports fast installation, while compression-resistant construction helps reduce waviness under the ridge cap. The vent is suitable for roof pitches from 2:12 to 20:12 and is designed for use in all climates.
