O'Hagin's, Inc. started as a roofing company over 30 years ago. Founded by Carolina and Harry O'Hagin, the company grew from a small shop into an international construction materials manufacturer. Committed to testing, O'Hagin's was one of the first companies to seek and secure testing approvals for attic ventilation products.

Today, O'Hagin's, Inc. has local and national testing approvals and is recognized for its industry-leading efforts in research and development. Currently, the firm holds 12 domestic patents and multiple international patents, with dozens more patent applications pending.

Research and product design represent only half of our story. We are dedicated to providing our partners -- architects, builders, roofing contractors, distributors and homeowners -- with the finest customer service possible. That's why we still climb on roofs, listen intently to our customers, and seek new ways to improve our products. Our goal is to continue to lead the ventilation industry, while providing the kind of one-on-one, personalized service and support you need to get your jobs done right the first time.
