Every roofing job is unique — as is every property owner. GAF Attic Ventilation Products provide effective, weather-resistant solutions that can help you differentiate yourself and business from competition, who are still offering property owners the same ventilation “solution”, regardless of job-specific needs. GAF offers an attic ventilation solution for virtually any roof style. From simple gable or “up-and-over” style roof designs with ample ridge line, our complete line of 4’ plastic, plastic roll, and mesh roll Cobra^® Ridge Ventilation Products are most suitable. For more complex “cut-up” roof designs with little or no ridge area, or simply tough-to-vent areas, reach for our broad line of Master Flow™ Off-Ridge Ventilation Products, featuring super slant-backs, roof-mount power vents and GreenMachine™ solar and dual-powered vents. For providing critical intake ventilation on virtually any job, Cobra IntakePro^® Rooftop Intake Vent helps avoid time-consuming and expensive work at the soffits - keeping roofers on the roof. GAF Attic Ventilation Products are eligible to fulfill the attic ventilation category for the WindProven™ Limited Warranty on GAF Shingles with LayerLock™ Technology and also qualify for GAF residential enhanced warranty coverage.
