Soffit Vents

Soffit Vents for Attic Ventilation

Soffit vents are likely the most important type of venting as they are used in conjunction with almost all other types of vents. The word soffit refers to the finished under side of the eaves. (see illustration below #1) Vents installed in the soffits allow air into the bottom part of the attic. While soffit vents can be used for both intake and exhaust of air they are most effective when combined with other types of vents that allow air out of the top of the attic.

Soffit vents come in two main design types:

  • Individual Soffit Vents - vent grates similar in appearance to those used with central heat and air are spaced evenly along the eaves. This is most common when retro-fitting soffit vents to an older home.


  • Continuous Soffit Vents - one long continuous vent (or several smaller vents placed end to end) run the length of the eaves allowing for even air flow into the attic. This is more commonly installed during new construction.

Soffit vents are not difficult to install and may only take a few hours depending upon the level of experience the installer has.

Roof vents can work well with most roof types or designs.
