A soffit is a finishing material, such as wood or fiber cement, that is designed to cover the underside portion of a roof’s overhang. Soffits serve many purposes, from protection from the elements to aesthetics to proper ventilation. Today we’ll discuss why soffits are so important to your roof replacement project.
Protection
Functionally, a soffit is designed to protect rafters from the elements, keeping moisture from infiltrating this area and growing mold. Mold can eat away at your exteriors and drastically reduce their lifespan, plus it looks unsightly and can cause health problems for your family.
Exposed rafters can also experience rot, which can be very costly to replace. Whenever you have your roof inspected, you should make sure the roofers check the condition of the soffit as well.
Ventilation
Vented soffits allow for proper airflow through the vents, which gives your attic constant circulation. When you have sufficient airflow, your attic won’t get too hot, thus preventing moisture-related issues such as rot and mold.
A superheated attic can make your shingles break down more quickly and can also lead to ice dam formation in the winter. Ventilation is essential in reducing humidity levels so mold and mildew don’t take over.
Plus, the hot air from your attic can seep down into your top floor and make your upstairs bedrooms hot and uncomfortable in the summer. Your AC unit has to work harder to keep things cool, which strains the system and can result in a reduced lifespan. This also leads to higher than normal energy bills.
Pest Prevention
Soffits prevent pests such as mice and squirrels from getting into your home via the gutters or roofline. Pests can not only damage your electrical system and roof, they can lower your indoor air quality due to droppings and urine, nest in your insulation, and chew through wires. As you can imagine, once you allow pests into your home, it’s very tough to get them out. You’ll have to hire a pest control company, which isn’t cheap, and it often takes several visits to get the infestation under control.
Appearance
Soffits can be any color you want, but most people go with white to make a sharp, clean contrast with their siding color. In addition to their functional benefits, soffits provide a finished appearance for your exteriors. Without them, the rafters would be exposed on the overhang’s underside, which can be unsightly. You can choose from smooth and wood-grain finishes depending on the style of your home, as most homeowners choose soffits that coordinate with the rest of their exteriors for a cohesive and polished look.
As you can see, there are many ways in which soffits can make or break your roofing project, so don’t overlook this important component.
