What is the role of a ridge vent in roofing systems?

The function of a ridge vent in roofing systems is primarily to allow hot air and moisture to escape from the attic. When a building is heated, particularly in colder climates, warm air rises and accumulates in the attic space. Without proper ventilation, this trapped hot air can lead to a variety of issues, including increased energy costs, potential damage to insulation and roofing materials, and the growth of mold and mildew.

Ridge vents are strategically installed along the peak of a sloped roof. They work effectively in combination with soffit vents located at the eaves of the roof, creating a natural airflow through the attic. As cool air enters through the soffit vents, the hot air escapes through the ridge vents. This passive ventilation system helps to maintain a balanced, healthy environment within the attic, reducing the risk of heat-related issues in the roofing structure.

Understanding this function underscores the importance of proper ventilation in roofing systems and highlights the ridge vent’s role in maintaining the longevity and integrity of the roof and overall building structure.
