Ridge Vent

Definition

A ridge vent is a construction element mounted along the ridge of a roof to aid in ventilating an attic space.

Purpose

The purpose of a ridge vent is to allow hot, humid air to escape from the attic, promoting proper air circulation and reducing the risk of moisture buildup, which can lead to mold and structural damage.

Examples of Use

• Ridge vents are commonly installed in residential roofs to improve attic ventilation and energy efficiency.
• Commercial buildings use ridge vents to maintain proper airflow and temperature regulation in large attic spaces.
• Ridge vents are part of a comprehensive roof ventilation system, often paired with soffit vents for optimal airflow.

Related Terms

• Soffit Vent: An intake vent installed under the eaves of a roof to allow cool air into the attic.
• Attic Fan: A fan used to exhaust hot air from the attic space.
• Roof Ventilation: The system of vents that provide air circulation in the attic space.

Notes

Proper installation of ridge vents is essential for effective attic ventilation, helping to extend the life of the roof and improve indoor air quality.
