What is a ridge vent?

A ridge vent is an exhaust opening that runs the length of a roof's peak, designed to let heated and humid air escape from the attic. It works as the exit point in an attic ventilation system, paired with soffit intake vents located under the roof overhang near the foundation line. Air enters through the soffit vents, circulates through the attic space, and exits through the ridge vent, creating continuous passive air flow that requires no power.

The system matters because it manages moisture and temperature in the attic. In the Hartford Metro area's humid climate, moisture buildup can lead to rot, mold, and deterioration of roof framing and insulation. Excess heat in summer drives up cooling costs and shortens shingle life. A properly installed ridge vent, sized to match the soffit intake area, keeps the attic drier and cooler year-round, extending the life of roofing materials and protecting structural integrity.

Ridge vents come in several styles, from basic slotted designs to higher-profile caps with baffles to prevent wind-driven rain entry. Installation is typically done during new roof construction or full roof replacement to ensure proper flashing and seal. Contractors working on roof replacement jobs in the Hartford area will often recommend adding or upgrading ridge ventilation if existing systems are inadequate or damaged.
