Soffits and Fascia Explained

Every roofing contractor understands the importance of soffits and fascia, but many homeowners don’t even know what these are. When caring for your roof, it’s important to maintain the soffits and fascias too, so it’s best to know what they are and why they matter.

Soffits And Fascia Explained

What Is a Soffit?

A soffit is the exposed surface underneath the roof’s overhanging section. This is part of the eave and is sometimes mistakenly referred to as the eave itself. In most roofs, the soffit has vents for drawing outside air. It works in tandem with other vents, such as ridge vents, where warm air and moisture are pushed out by the incoming outside air. In the U.S., most soffits are made of vinyl or wood. Vinyl is a better choice for preventing moisture intrusion. It also doesn’t rot.

What Is a Fascia?

A fascia, on the other hand, is the vertical board at the edge of the roof. This is connected to the ends of the rafters and trusses, which are where the roof is attached. The fascia acts as a protective layer between the edges of a roof and the elements. As it is a vertical board, it is also highly exposed, so it contributes to the home’s curb appeal.

Common Forms of Damage to Soffits and Fascia

Roofing companies often remind homeowners to maintain their soffits and fascia boards because these are exposed to the elements so they are just as prone to damage as other parts of the building’s exterior. Damage to soffits and fascia boards is often caused by moisture penetration, rot, and improper installation. Wood is susceptible to water damage, so your wood soffit or fascia can suffer from this problem over time. Corroded nails can also cause them to come loose. 

When soffits and fascia are no longer protecting the roof, more moisture can enter, causing more damage. Wind-carried dirt and debris can also find their way into your roof. What’s worse is that they can become entryways for small animals and insects, including rats, cockroaches, ants, and termites.
