Madison Roofing: Article About Soffits
In most homes, the roof overhangs the outside wall. This creates an exposed area of the attic, where water, insects and even animals can get in. To protect the attic and a home's structural components from the elements, soffits are normally installed. Along with protecting an attic, soffits may also be vented to help air flow through the attic, which is an important part of protecting Madison roofing from heat damage and ice dams.
The two most common types of soffits are vinyl and aluminum. They are both fairly affordable, but vinyl tends to be less expensive. Both materials will perform fairly well in most environments, but aluminum generally works better in sunny and humid environments.
Vinyl soffits offer the best insulation, and they are available in a wide range of colors and textures. They are also resistant to cracking and they will not rot. However, if they are exposed to the sun for long periods of time, they may discolor or become brittle, and they may develop mold in areas with a lot of humidity.
Soffits made of aluminum are more expensive, so the costs can add up in large homes, but they have the advantage of being more malleable, so they are easier to install. They also will not rot, and they won't chip or crack either, and they are essentially water proof.

However, they may dent if enough force is applied to them.
Vented soffits are a popular way of ensuring that air can flow through an attic. They are normally designed so that vents or openings are slanted, so they still keep debris out while letting air in.
When vented soffits are installed, they are normally put in along with baffles and ridge vents. Baffles are plywood sheets that can be installed with staples, and they are used to create a path for air from soffits to flow through. Without baffles, air may end up disturbing insulation, which needs to be compacted to work efficiently.
The other advantage of baffles is that they allow the area around where air flows through to be completely insulated, which also ensures that air ducts are not exposed to heat transfer from outside air. Baffles will normally ensure that air flows up to the top of the attic, where ridge vents let air out.
Ridge vents are installed at the apex of a roof, and they are covered so that air can flow out without anything getting in. In some cases, vented gables are used instead of ridge vents, but they have fallen out of favor in the last few years.
