The soffit plays an integral in protecting your home from the elements. In this post, we discuss the function of the soffit and its importance in preventing moisture damage.

Where the Soffit Is Located

Your roof’s soffit is located under the fascia board, the long straight board that your gutters are attached to. Not all homes have soffit boards. For instance, homes with no overhang don’t have them.

Soffits and Roof Ventilation

Soffits, which are installed on the lower portions of your roof, have holes that allow your roof to “breathe.” Fresh air enters your attic through the soffit, pushing warm, stale air out. This venting process prevents moisture retention in the attic. Without adequate ventilation, moisture and heat accumulate inside the attic, potentially causing several issues requiring roof repair.

In addition to providing ventilation, soffit boards protect your roof’s rafters—wooden beams providing structural support—from the elements. However, the level of protection varies depending on the material used to manufacture the soffit board. Similar to siding, certain kinds of soffit boards are more suited to specific climates.

Here’s a quick overview of the most common types of soffit boards:

Vinyl soffit boards – Vinyl soffits are the most affordable option for homeowners. They’re easy to clean and resistant to moisture damage.
Aluminum soffit boards – This kind of soffit board is recommended for areas that receive a high amount of rainfall. Aluminum soffit boards are durable, rot and corrosion resistant, and low maintenance.
Timber soffits – Timber soffits retain natural wood’s classic aesthetic, making them a good choice for homeowners looking to give their roof a rustic feel.

If you’re having trouble choosing a soffit board for your roof, consult an experienced contractor.
