A ridge vent is a type of roof ventilation system installed along the peak of a sloped roof. It allows hot, humid air to escape from the attic, helping to regulate temperature and moisture levels. This ventilation method is essential for preventing issues like mold growth and roof damage. Ridge vents work in conjunction with other ventilation systems, such as soffit vents, which are located under the eaves of the roof. Together, they create a continuous airflow, promoting better energy efficiency and extending the lifespan of the roof and the overall structure of the building.
