Roof Ventilation Systems: Cor-A-Vent V-300® and V-300E Ridge Ventilation System

The V-300® ridge vent is Cor-A-Vent's most popular ridge vent for a variety of reasons -- from ease of installation, to its low profile and power-nailability, the V-300 provides the best value for a ridge vent on the market today. It works equally well under shingles as well as shakes or slate roofing. If you are looking for a low profile ridge vent that still provides plenty of ventilation, our V-300 product line is your answer.

V-300E Enhanced ridge vent is ideal for hip use (NOTE: Minimum pitch for hip use is 5/12). V-300E's low profile on the hips allows it to blend in with the roof. V-300E is also available in 11", 8 1/2" and 7" widths and feature the Enhanced Snow Screen™ to prevent fine snow from entering the ridge vent.
