One effective method to improve attic ventilation is by adding more passive vents. Passive ventilation relies on natural airflow, allowing fresh air to enter through intake vents at the eaves or soffits and exit through exhaust vents located at the ridge or higher points of the roof. By increasing the number of passive vents, you enhance the overall airflow within the attic space, helping to regulate temperature and moisture levels. This process is crucial in preventing issues such as mold growth, roof deterioration, and energy inefficiencies due to overheating in the summer months.

Effective attic ventilation is essential for maintaining a healthy home environment and protecting the structural integrity of the roofing system. Ensuring that there are sufficient passive vents can help achieve a balanced airflow, which also allows for more efficient removal of heat and humidity that can accumulate in the attic.
