TL;DR
A gable vent is the louvered opening set high in the triangular end wall of a roof that lets attic air exchange with the outdoors, available in vinyl, aluminum, and wood in round, rectangular, and triangle shapes. On sheds it is often the only ventilation, paired one per gable so air crosses the attic space and carries off heat and moisture that would otherwise condense on the underside of the roof deck.
What it means
A gable vent is the louvered opening set high in the triangular end wall of a roof that lets attic air exchange with the outdoors, available in vinyl, aluminum, and wood in round, rectangular, and triangle shapes. On sheds it is often the only ventilation, paired one per gable so air crosses the attic space and carries off heat and moisture that would otherwise condense on the underside of the roof deck. In houses with ridge-and-soffit systems, open gable vents can short-circuit the intended airflow and are sometimes deliberately blocked.
