Air flow Ridge vents are the newest and greatest venting innovation. It seems like these have quickly become one of the more popular venting options. Air flow Ridge vents are designed to be installed at the peak of a roof slope. They are almost not visible to the naked eye, which perhaps contributes to its popularity. Air flow Ridge vents are slightly more expensive than other vent options. Air flow Ridge vents come with several advantages. When installed correctly they can provide a high volume of airflow per square meter, since the entire ridge acts as a vent instead of just one or two locations across the roof. The ridge must be installed along the entire roof to prove effective these vents are designed to provide an even distribution of air, rather than just venting specific spots or areas. This feature helps to make this one of the most efficient roof venting options nowadays.
