The Cobra IntakePro Rooftop Intake Vent from GAF allows cool air into the attic; pushes moist, warm air out; and helps guard against roof system rot, ice damming, and mildew growth. The manufacturer says the vent can improve attic airflow by up to 20 percent when installed with existing soffit or under-eave vents. The IntakePro eliminates time-consuming alterations at the soffit, and is easy to roll out and install with the included 1¾-inch coil nails. It’s best used on roof pitches 4:12 and greater, and can be installed at the eaves’ edge or up-slope areas of the roof.
