Roof vents are a type of ventilation system designed to improve air circulation and temperature control in buildings. They are typically installed on the roof of a building and work by allowing hot air to escape while drawing in cooler air from the outside. This helps to regulate the temperature and humidity levels inside the building, which can be particularly beneficial in warmer climates or during the summer months. In addition to improving air quality, roof vents can also help to prevent moisture buildup and reduce the risk of mold growth. Overall, they are a useful addition to any building looking to improve its indoor air quality and energy efficiency.
