Proper roof ventilation is crucial for maintaining a healthy and energy-efficient home. It helps to regulate the temperature and humidity levels inside the attic, preventing the buildup of moisture and heat that can cause damage to the roof and insulation. Additionally, adequate ventilation can reduce energy costs by keeping the attic cooler in the summer and preventing ice dams from forming in the winter.

There are two main types of roof vents: intake vents and exhaust vents. Intake vents are located at the bottom of the roof, usually in the soffit or eave, and allow cool air to enter the attic. Exhaust vents are located at the top of the roof, such as ridge vents or gable vents, and allow hot air to escape.

The amount and placement of roof vents depend on several factors, including the size and shape of the roof, the type of insulation, and the local climate. As a general rule, the total net free area of ventilation should be at least 1/150th of the attic floor area, with half of the vents located at the top of the roof and half at the bottom.

Regular maintenance of roof vents is essential for ensuring optimal performance. Over time, vents can become clogged with debris, such as leaves, dirt, and bird nests, which can impede airflow and reduce ventilation efficiency. Cleaning the vents at least once a year can help to prevent these issues and extend the lifespan of the roof.
