What Is Exhaust Ventilation?

Exhaust ventilation allows warm, humid attic air to leave the roof system through ridge vents, box vents, or other high vents.

Exhaust ventilation gives warm, humid attic air a place to exit. Common exhaust vents include ridge vents, box vents, and other vents installed high on the roof.

Why It Matters

Heat and moisture trapped in the attic can affect comfort, roof performance, and winter roof conditions. Exhaust ventilation helps move that air out when proper intake is present.

Common Problems

Problems include blocked vents, mixed ventilation types that work against each other, too little intake air, improperly cut ridge openings, and vents installed in the wrong location.
