How Does Soffit Venting Work?

Lead Image

Soffit venting is a type of venting method that allows air to flow into your attic from under your roof. One benefit of soffit vents is to minimize moisture. During humid days, moisture inside the attic may build up and condense to form water. This water can cause a considerable amount of damage to your home. To minimize the build-up of moisture, you need soffit vents in conjunction with ridge vents or any other type of exhaust vents.

The Purpose of Attic Ventilation

Proper attic ventilation protects a home and its occupants from the effects of temperature swings. During the summer, hot air inside the attic causes the temperature inside the home to rise as well. Soffit venting mitigates this temperature build-up, reducing the need for air conditioning as well as protecting the home from the damages caused by extreme heat.

During the winter, soffit ventilation keeps the roof cold, preventing snow from melting on your roof, flowing down into your gutters, and refreezing as an ice dam, which can cause significant damage to your home. Soffit ventilation also reduces mold-causing moisture inside the attic.

How Soffit Vents Work

Soffit vents are intake vents installed in the eaves to draw in cool air from the outside and allow warm air to escape out of the exhaust vents. Soffit vents are never installed without other types of vents installed at a higher location to draw air and moisture out of the attic.
