This video demonstrates how the external baffle of Shingle-Vent II makes it a better protectant against water infiltration in comparison with several different styles of ridge vents. Architectural Testing Labs tested the consistent reliability of Shingle Vent II by installing each ridge vent according to manufacturers’ instructions on a 4-12 roof. They then monitored the roofs to see how much water leaked through each vent. The video footage reveals how the external baffle of Shingle-Vent II protects the attic from rain infiltration even under drastic wind conditions of 110 mile wind speeds. The external baffle deflects wind over the vent preventing rain infiltration into the attic, while other ridge vents allowed in 2-4 gallons of water. For example, the VentSure ridge vent leaked more than 2 gallons of water, the Roll Vent ridge vent leaked more than 3 1/3, and the RidgeMaster ridge vent leaked more than 3 1/2 gallons. The Shingle-Vent II, on the other hand, with its external baffle did not permit any water to leak into the attic.
In comparison with several different ventilations systems, the Shingle-Vent II ridge vent lets in less water and snow. In considering ridge vents, you may be wondering why having a ridge vent that is weather resistant is so important. If you install a ridge vent that is not weather resistant, water and snow that infiltrates your attic can cause damage there or elsewhere in your house, and you may not even know it is leaking until it’s too late. Be sure to thoroughly investigate your ridge vent options to confirm that you are making a worthwhile investment into improving your home.
