Soffits and Fascias: What’s the Difference?

When you’re having some work done on your roof, it’s possible that you heard your general contractor throw the words ‘soffit’ and ‘fascia’ around. For those who are unaware, these two are important components of your roof that prevents mold and mildew from entering your home’s rafters as well as increase the air ventilation of your home. While they may sound like a similar thing or even a single unit, what some homeowners don’t know is that they’re actually two different things with key characteristics that set them apart from one another.

In this post, 3JM Exteriors, Inc. discusses how a soffit and fascia differ from one another.


One of the glaring differences between a soffit and fascia is where their secondary purpose. A soffit is usually placed in the area beneath the eaves of your home’s exterior to close the space beneath it. It also extends from the side of your home toward the edge of the eave. Fascias, meanwhile, are used to create a barrier between your roof edge and the outside, creating a smooth appearance and protecting the roof from weather damage.


In terms of durability, the soffit is much more vulnerable to the elements compared to any other part of your home. This is because it’s constantly exposed to water flow from torn shingles, rusted flashing and malfunctioning gutters. Pests can also make their nests in the spaces behind your soffits and cause further damage. Fascia boards aren’t as susceptible to moisture damage as soffit but they can detach from the structure and will need to be replaced by a roofing and siding repair professional.


Usually, soffits are made of vinyl or aluminum but wood can be used in some cases as well. If you choose a vinyl or aluminum soffit, you have a wide range of color options that will allow you to match the siding of your home. Fascias, on the other hand, are often made of wood but can be purchased in plastic and aluminum.
