What is a ridge vent and how does it work?

• A. A vent along the roof ridge that allows warm air to escape from the attic, promoting ventilation.
• B. A pipe that drains water from the gutter.
• C. A sealant used on flashing tapes.
• D. A decorative feature with no ventilation purpose.

Answer: (A)

A ridge vent is a vent installed along the roof peak that lets warm, moist attic air escape, aiding ventilation. It works by providing a continuous exhaust path at the highest point of the roof. When paired with intake vents at the eaves or soffits, cooler outdoor air is drawn in at the bottom as warm air rises and exits through the ridge. Wind can also help push air along the vent, enhancing the flow. This natural convection and wind-driven ventilation keep attic temperatures lower, reduce moisture and condensation, and help prevent issues like mold, ice dams, and accelerated roof deck aging. Ridge vents are typically covered with a cap or screen to block rain and pests while remaining breathable. It isn’t a gutter-downspout, which drains water from the gutter; it isn’t a sealant used on flashing tapes; and it isn’t a decorative feature.
