Ridge Vent
Definition and meaning of Ridge Vent in real estate.
A ridge vent is a continuous ventilation strip installed along the peak of a sloped roof to allow warm, moist air to escape from the attic. It works in conjunction with intake vents under the eaves to maintain proper airflow.
In more detail
Proper attic ventilation is essential for preventing moisture buildup and regulating temperatures throughout the year. As hot air rises naturally, a ridge vent provides a clear exit path at the highest point of the roof. This passive system pulls cooler outdoor air in through soffit vents located at the bottom of the roof line.
Good ventilation prevents condensation that can rot wood framing, reduces the risk of ice dams in winter, and lowers cooling costs in summer. Ridge vents are typically covered with shingles to blend seamlessly with the roof line while keeping out rain, snow, and pests.

Frequently asked questions
Do ridge vents leak when it rains?
When installed correctly with a protective external baffle, ridge vents are designed to block wind-driven rain and snow from entering the attic.
Can you have a ridge vent without soffit vents?
No, ridge vents require intake vents, like soffit or eave vents, to create the continuous airflow needed to ventilate the attic properly.
