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.
Exterior Echelon Notes
Exterior Echelon reviews exhaust ventilation as part of the full roof system and checks whether it is balanced with intake ventilation.
