Does the ridge vent’s external baffle trap debris, pine needles and other weather elements?
A. Generally, leaves and debris that can fall in behind the external baffle are not a concern because of the low pressure created by the external baffle when wind hits it — essentially self-cleaning the ridge vent. In Air Vent’s video you can see in the wind driven rain tests that there is a significant amount of low pressure created which can draw water up and out of the ridge vent. Thus, leaves and debris are not an issue.
