What a ridge vent is

A ridge vent is an exhaust vent installed along the ridge — the peak or highest line of the roof. It runs along the ridge and allows hot air and moisture to escape from the attic at the highest point. Ridge vents are typically low-profile, blending into the roofline rather than protruding like some other vent types, which gives them a clean appearance. The ridge vent works by providing a continuous exhaust opening at the top of the roof, where hot air naturally rises.

How ridge vents fit into the ventilation system

A ridge vent is one half of a ventilation system — the exhaust half — and it works with intake vents to create airflow. The principle is that air enters through intake vents low on the roof, typically soffit vents at the eaves, and exits through the ridge vent high at the peak.

Benefits of ridge vents

• Provide continuous exhaust along the entire ridge.
• Low-profile design for a clean aesthetic.
• Naturally leverages heat rising to the peak.
• Proven, effective solution when paired with proper intake.

Why balanced ventilation matters

The key to ventilation working is the balance between intake and exhaust. A common mistake is having exhaust like a ridge vent without adequate intake, or blocked intake vents, which prevents the system from working properly.

Common ventilation mistakes to avoid

1. Inadequate or blocked intake vents.
2. Mixing incompatible exhaust types.
3. Inadequate overall ventilation for the attic size.
4. Improper installation compromising water tightness.
