If you’re reading this article, you’re probably somewhat familiar with roofing components. And you’ve probably encountered two terms: soffit and fascia. These two are crucial ones that work together in order for the interior parts of a roof to be protected. They also help to protect hard-to-paint areas in a home and considerably increase air ventilation. Since they work closely together, the terms are often mixed up.

In truth, these roof components are not the same in definition or in usage.

• Soffit – The bottom part or underside of a building’s element like a projecting cornice, a flight of stairs, or an arch is a soffit. Other types of soffit include the horizontal vinyl or aluminum piece covering the overhang of your roof. They’re usually made of aluminum or vinyl; in some cases, wood is used. 

• Fascia – The board running along a structure’s ends. This is where guttering and similar exterior elements are attached. Spaces between the roof and the soffit are covered by horizontal pieces, which are fascia boards. While the usual material is wood, it can also come in aluminum or plastic.

Durability of Soffit and Fascia

Water damage is not quite likely for fascia boards, but if they’re exposed and seem to be rotting, replacement is imminent. That’s because they will end up detaching, which defeats their purpose. The most vulnerable part of your home is easily soffit. Squirrels and birds like nesting behind it when they find a way inside. Additionally, it’s consistently exposed to torn shingles, rusted or damaged flashing, and gutters that are malfunctioning. In turn, there’s always a lot of water flowing, which leaves the soffit quite vulnerable. When there are signs of rot or damage, it must be replaced immediately. 

Installing Soffit and Fascia

Soffit, by design, is installed from the exterior wall all the way to the fascia board. It’s typically hidden at the back of the fascia, under the eave. For a properly constructed roof, fascia is integral, usually installed behind gutters and behind the roofline. It’s around the whole structure, attached to rafters’ uncovered ends or the top part of exterior walls.

In some cases, the roof is flush with the edge of exterior walls. When that happens, the fascia itself can have soffits for vent purposes. 

The Uses of Soffit and Fascia

As previously mentioned, the fascia is where the drainpipes and gutters can be attached. It’s the barrier between the outside and the roof, giving the edge a smooth appearance. There are roof fascia types that can be chosen from. It also contributes to weather damage protection. On the other hand, the soffit runs from the structure’s side to the eave’s edge. It’s used in the area under the eaves of a house’s exterior for the eave to be closed.

Conclusion

Soffit and fascia are two of the most integral parts of a roofing system. They work closely together in order to protect a roof’s interior, which is why the terms are often mixed up. Soffit is the underside of a building’s element; fascia is the board running across a structure’s ends.
