How well does ShingleVent II work to prevent weather infiltration compared to other ridge vents?
ShingleVent II passes Dade County tests without a drop in the bucket. In rain infiltration tests conducted in accordance with the Dade County Building Code Protocol, different styles of ridge vents were installed according to manufacturers’ instructions on a 4/12 roof. After being subjected to rain and winds that varied from 35-110 mph, ShingleVent II passed the test without even a drop in the bucket. As you can see from the chart at right, other ridge vents didn’t fare so well.
