What Is Fascia on a House? Your Questions Answered

Building systems are complex, with lots of little architectural details that all combine to create a solid structure. You’re probably already familiar with the larger elements of your home’s construction: the foundation, the framing, the roof, the windows, and so on. But your home’s fascia is one of those architectural details as well.

So, what is fascia on a house? And why does your home need it? Read below, and we’ll explore the answers to all of your fascia-related questions.

What Is Fascia on a House?

When you’re looking at your home’s roof overhang, look at the horizontal board that runs along the lower edge of the roof, just under the eaves and just above the soffit. This is the fascia board — and it’s the reason why you don’t see the exposed ends of roof rafters or trusses. The fascia board is in part a piece of trim designed to cover them.

What Is the Purpose of Fascia Boards?

Fascia plays an incredibly important role as part of your home’s roofing system. For one thing, because it covers the ends of trusses or rafters, it’s key to giving the roofline a finished look that greatly enhances the home’s curb appeal.

Fascia also does all of the following:

• It offers support by creating a solid base for the bottom of the roof’s decking, shingles, and gutter system.
• Fascia provides a place to fasten soffit material beneath the home’s eaves.
• It seals the open spaces between rafters and trusses, which prevents drafts and water infiltration.
• Fascia also seals the roof structure against wildlife like birds, squirrels, raccoons, and other animals that could otherwise squeeze into the gaps between rafters to take up residence in your attic space.
• It works together with the soffit to facilitate continuous airflow. The soffit allows cool outdoor air in while the fascia prevents a buildup of excess heat in the attic.

As you can see, fascia is an important part of your home’s aesthetics and structural integrity. 

What Types of Fascia Materials Can Be Used?

Since most homes are either stick-built (primarily made using wood framework) or built from another material with wooden roofing framework, most fascia is also made of wood. However, homes with steel framework may have structural steel in place of fascia. On steel-framed homes, this component is sometimes referred to as an “eave strut.”

Vinyl, PVC, steel, and aluminum fascia also exist — and these products can cause a little bit of confusion among homeowners. That’s because most manufacturers use the term “fascia” interchangeably to refer to both the wooden fascia boards that are part of your home’s framing and the metal or vinyl fascia coverings that you see from the outside. 

That’s why most of the vinyl and metal fascia that you’ll find available for purchase is made from thin sheets of material. Since they’re not thick enough to provide structural support, these are actually covers for wooden fascia. 

If you choose to use vinyl or steel fascia, you’ll still need a fascia board beneath the covering — not only so that you have something to attach the fascia covering to but also to provide essential structural support to your roofing system.

Is Steel Fascia Better Than Wood?

The short answer to this question is yes, steel is much better than wood! 

However, as noted above, most steel fascia — including TruLog’s steel fascia — is a covering that is designed to go over the existing wood fascia rather than replace it entirely. Even so, it’s still a smart addition to your roofing system, and here’s why.

Beautiful Finishes

Steel fascia helps you create a beautiful, finished appearance for your home. It’s available in a multitude of trendy colors so that you can easily match the fascia color to your home’s siding or trim color. You can even use TruLog’s TruGrain and HD Woodgrain finishes to get the look of walnut, pine, and other natural wood shades.

Better Durability

Steel fascia serves as an outer protective layer to the wood fascia board. It’s high durability helps the wood beneath last longer by preventing moisture infiltration and pest damage.

Low Maintenance

Steel fascia is a low-maintenance option. As wood fascia is exposed to the elements, it can cause peeling paint, which means it will need to be repainted every few years, and you’ll likely need to replace it with new fascia every 10 to 20 years when wood rot sets in. 

But when you cover wood fascia boards with TruLog’s steel fascia, not only will you be extending the fascia’s lifespan by preventing UV and water damage to the wood beneath, but you’ll also never need to worry about repainting or other types of regular maintenance.

Is Steel Better Than Vinyl?

TruLog’s steel fascia also outperforms vinyl fascia. While vinyl can help keep wooden fascia boards in good condition, pests can still chew it, and it can still sustain impact damage.

TruLog steel fascia comes with a Class 4 impact rating, which is the best rating possible. On top of that, with a Class A fire rating, TruLog’s steel fascia is also the most fire-resistant choice.

When Should Fascia Be Replaced?

The answer to when fascia should be replaced varies depending on what material you fascia is made from. Different materials will display different signs that it’s time for a replacement. Below, we’ll show you what to look for when it comes to wood, vinyl, and steel.

Replace Wood Fascia When:

• It shows signs of mold or rot, which will affect the roof’s structural integrity.
• You can see signs of insect damage.
• It features marks or holes where rodents or woodpeckers have damaged it.

Replace Vinyl Fascia When:

• It has started to warp or sag with age.
• The color has faded in the sun.
• It has punctures, cracks, or has become brittle.

Replace Steel Fascia When:

• Something has managed to puncture it.
• It has been scratched or dented due to a severe impact.

If your home has steel fascia, chances are good that the steel will outlast the wood fascia beneath it. For this reason, when you’re evaluating whether fascia needs to be replaced, it’s a good idea to tap along the length of steel fascia. If the steel flexes inward too much or makes an odd, hollow-sounding noise, it may be worth taking a peek beneath the steel to see whether the wood has been damaged by rot or pests.
