Ridge vents are a type of roof ventilation system installed along the peak of a roof. They allow hot air and moisture to escape from the attic, helping to regulate temperature and prevent damage from excess humidity. This ventilation method is often used in conjunction with soffit vents to create a balanced airflow throughout the attic space. Made from materials like metal or plastic, ridge vents are designed to blend seamlessly with the roofline. They are typically covered with a protective mesh to keep out pests and debris while allowing air to flow freely. Proper installation of ridge vents can enhance the longevity of a roof and improve energy efficiency in a home.
