Fascias and Soffits: What’s the Difference and Why Are They Important?

You know that your roof is an essential element of your home. It protects you and all your stuff so problems with the roof can be devastating if not caught before an epic storm rips through your neighborhood.

But do you also know about and understand soffits and fascias? We’ve found that many homeowners don’t. 

These architectural elements help protect your roof so your roof can keep on protecting you.

What on earth are soffits and fascias? And why are they important to your roof?

Soffits are the finishing touch under your eaves. If there weren’t soffits, the bottom part of the eave would be open and exposed to the elements. 

You can’t see the soffits unless you’re standing right under the eave and looking up, so they don’t really affect the curb appeal of your home as much as your roof or siding. Soffits can be made from the same material as the siding on your home. They are also commonly made from aluminum, wood, and vinyl.

Why Are Soffits Important?

It’s not often that rain travels up (thankfully), so you may be wondering why soffits are so necessary. 

It’s true that water won’t be pouring into your home without the soffits, but over time splashback and other sources of water can get up into the roof. Moisture in the roof is a recipe for disaster. If it occurs frequently and is there long enough you’ll have a rotting roof.

The soffits also help keep rodents, bees, and other unwelcome critters out of your home. 

Completely sealing off the eaves isn’t a good idea either. The attic needs proper ventilation. Without it, moisture in the air can condensate and build up, causing mold in the attic and other problems. 

That’s why you have soffits vents to help provide adequate air circulation. They also offer another way for hot air to escape from the attic during the summer months.

Fascias: What is fascia on a house? 

Fascia are the flat boards perpendicular to the roof that finish off the edges. 

Gutters, if you have them, will be installed along the fascia. 

Fascia on a house do affect your home’s curb appeal so you’ll want to keep them in good shape.

It’s important to choose a material that is easy to maintain and you won’t have to worry about them as often.

Why Are Fascias Important?

In addition to protecting the ends of your rafters, house fascia support the last line of shingles on your roof. Without them, the shingles could bend and even snap off during strong winds. 

They also provide a sturdy anchor point for mounting the gutters. Be sure to keep your gutters clean at all times to avoid water pooling along the house fascia. This could lead to rot and mold if left for too long.
