Ridge Vent

Ridge vent is a continuous exhaust vent installed along the entire peak of the roof, hidden beneath the ridge cap shingles. It lets hot, moist air escape from the attic along the full length of the ridge — the most even and effective exhaust ventilation available.

Ridge vents work on simple convection: hot air rises to the peak and exits through the vent's baffled openings, while cooler replacement air enters through soffit vents below. The external baffle design deflects wind and rain so weather stays out while air flows freely.

For a ridge vent to work, two things are required: continuous soffit intake below, and no competing exhaust vents (like box vents) that short-circuit the airflow. A ridge vent cut into the deck but starved of intake air does almost nothing.

Why It Matters

Ridge vent plus soffit intake is the gold standard of residential attic ventilation — quiet, invisible, with no moving parts. If your roof lacks it, adding a ridge vent during the next roof replacement is one of the best upgrades you can make.

A Maryland Note

Maryland's humid summers make attic heat and moisture a double problem — ridge vents run 24/7 with no energy cost, which matters during our long cooling season.
