What is a ridge vent?

A ridge vent runs along the entire peak or ridge line of a roof, creating an exhaust point for hot and humid air trapped in the attic. It works as the upper part of a balanced attic ventilation system, typically paired with soffit vents or other lower intake vents that bring cool air into the attic space from beneath the eaves.

The vent itself is usually made of plastic, metal, or foam material with a slotted or perforated design that allows air to escape while preventing rain and debris from entering. When installed correctly, hot air rises and exits through the ridge vent, while cooler outside air is drawn in through intake vents below, creating natural air circulation that removes moisture and heat buildup.

Proper ridge ventilation protects the roof structure by reducing temperature extremes that can shorten shingle life, preventing ice damming in winter climates, and limiting moisture that can lead to rot or mold in rafters and roof decking. A well-functioning ridge vent system also helps regulate attic temperature year-round, which can ease the load on air conditioning systems in summer and reduce condensation in winter.

If you need to assess whether your ridge ventilation is working effectively, local roofing contractors in Greater Hartford can inspect your attic ventilation system and advise on repairs or upgrades.
