Which is Which? Soffit vs. Fascia

Soffit and fascia are two key components of a home’s exterior that might be confusing to homeowners. Because they work in tandem and are closely aligned with both the roofing and gutter systems, it’s important to understand the role they each play in protecting a home’s exterior.

What’s the difference between soffit and fascia?

Fascia board is typically a 1×6 piece of pine wood that the gutter system attaches to. The forward-facing fascia board is capped or wrapped with aluminum so the wood doesn’t rot. 

Soffit is the material that closes off the space between a roof’s overhang and an exterior wall. While this space, or underside of a roof’s overhang, can be exposed (something you see on victorian homes where rafter tails are visible), the majority of homes these days have soffit. Homeowners don’t want birds building nests in the space, or squirrels getting into attics. 

Soffit used to be made of wood, but wood is expensive and is a finite resource. With modern building, we’ve now moved towards synthetic materials that require less maintenance like vinyl. 

What are some signs soffit or fascia needs to be repaired?

If you have wooden soffit or fascia that hasn’t been maintained, paint will begin to wear off, peel, or deteriorate. Once the wood underneath the paint is exposed to the elements, it becomes compromised and will begin to rot over time. This is why it’s important to cover or cap fascia boards, and use vinyl material for soffit. 

Rotted wood doesn’t hold nails. If you see boards that are loose or hanging down, this is another tell-tale sign you’ll need a repair or replacement. 

Can you make these repairs yourself, or should you call in a professional?

Something that’s extremely important for homeowners to understand is if you’re repairing or replacing soffit or fascia, that means you also need to remove and reinstall your gutters. And if you’re demoing old soffit or fascia, you must do so without damaging or compromising your roofing system. Soffit and fascia board are attached to each other, attached to gutters, and attached to your roof — it’s complex. 

This work can happen at an elevation of 10 feet or more, and depending on your roof’s pitch requires maneuvering up and down ladders or scaffolding. 

There are many DIY projects that homeowners are capable of tackling, but this is one that’s best left to the pros.

What are some best maintenance tips to keep soffit and fascia in excellent shape?

If you live in a house with wooden fascia and soffit, the best thing you can do is keep up with paint. Every few years, depending on the climate in which you live, you’ll need to re-paint. 

If paint has already deteriorated and the wood is compromised, applying another coat of paint over top won’t act as a big fix. 

To avoid the possibility of wood rot, use modern building materials like PVC-coated aluminum capping/flashing and vinyl soffit. 

Lastly, make sure soffit is vented or perforated to let fresh air flow through the space between rafter tails and the wall — without exposing it to the elements, critters, or pests. Any professional roofing or siding installation contractors will use vented soffit.
