Soffit siding is the exposed [siding](https://www.masterclass.com/articles/exterior-siding-options) beneath your roof's overhang that is rarely visible from the street. If your home does not have any roof overhangs, then your home does not have any soffits. Manufacturers make soffit out of aluminum, wood, or vinyl siding. Vinyl soffit panels are popular because the material is durable, impact-resistant, and nearly maintenance-free.

Soffits are either vented or non-vented. Vented soffit panels feature small holes that provide airflow into and out of an attic space, allowing for cooling in the summer and heating in the winter. Non-vented soffits lack holes and are commonly found in plywood soffits.

To better understand soffit, you may want to think of it in relation to fascia, which is the exposed board on the front of your overhanging roof and the portion of the siding just above the soffit. Installers affix gutters and fascia to the soffit material between the eaves at the edge of the roof. To maintain a home’s curb appeal, homeowners keep the highly visible fascia in good condition.
Soffit siding—part of a home’s roofing system—attaches to the underside of overhangs and fulfills a couple of key purposes: 

1. __Enhances aesthetics__: Soffits can give your home a more finished look. Without them, the rafters on the underside of your roofing are visible—for example, on covered porch ceilings. Soffits are available in a variety of colors, materials, and styles, including wood-grain and smooth finishes. To give your home a uniform and polished appearance, it's typical to invest in a soffit that matches or coordinates with the rest of your external design.
2. __Improves ventilation__: The primary reason for installing a soffit on your home is to achieve proper ventilation. In addition to the underside of your roof deck, soffit will cover at least a portion of your attic area (if your home has one). Heat accumulates in attics over time as a result of both the sun pounding down on the home and energy use inside the home. Soffits are a ventilation system unto themselves, enabling air to circulate and heat to escape, which can assist with keeping your electricity bills lower in the summer.
3. __Controls moisture__: The venting that soffit installation provides can help keep moisture out of the region immediately beneath your roofline, thereby preventing water damage, wood rot, mold growth, and ice formation. These issues can be at best inconvenient and at worst can lead to roof repairs or even total roof replacement—significantly costly outcomes, especially if elements of your roofing system are not covered by a warranty or other kind of insurance.
Here are some maintenance tasks you can complete to keep your soffits in good condition so that your home remains well ventilated: 

1. __Check for pests__. Spaces directly below your roof or areas that lead into your attic can be ideal entry points for pests—such as mice, rodents, insects, and birds—to infiltrate your home. Periodically check for broken soffits, which leave you extra vulnerable to pest problems, and fix them swiftly. Additionally, check regularly for pest damage so you can treat the issue or hire a professional.
2. __Clean the soffits__. Soffits, like most external finishing components, such as gutters and fascia, have a moisture-resistant protective coating; however, you should not spray water directly on soffit vents. To help clear them of dirt, dust, and other material, use compressed air on your vented soffits at least once every two years.
3. __Inspect for signs of wear__. Perform low-maintenance upkeep on your soffit panels just by inspecting them regularly for minor holes caused by rust, decay, or peeling paint that could impact their overall durability. To avoid water damage, you should keep vinyl soffit panels thoroughly sealed and caulked, so examine them for cracks or worn spots in the sealant or caulking and consider making reapplications of both a part of your regular home improvement routine.
4. __Scrub the gutters__. Use a mild detergent to clean your gutters at least twice a year to eliminate filth and stagnant moisture from the areas, since mold and mildew can grow on solid vinyl soffit or aluminum soffit if they come into prolonged contact with moisture.
