A Guide To Attic Ventilation Options, Costs, And Installation

Providing proper attic ventilation is an important home improvement task. It allows air to circulate and prevents mold and moisture from forming in the attic. It also helps to maintain the attic atmosphere and keep it cooler during the warm months of the year. It also protects the roof structure from heavy winters.

There are several types of attic vents that homeowners can choose from. Static and powered roof vents are both great options, but the best is a rafter vent. Rafter vents create narrow gaps between the rafters, allowing fresh air to enter the attic. Rafter vents also help to minimize the chances of moisture damage to the roof. They can also reduce the chance of negative pressure, where attic air pulls in fresh air from outside the home.

A powered vent is a special type of roof vent that uses a thermostat and a balanced motor. It works by pushing air in and then letting it go. It is a good choice for large homes with How To Tell If Your Attic Is Properly Vented? large attics. A powered vent also helps to exhaust humidity from the attic.

Another great option is a turbine-style roof vent. These vents work by using a light breeze to rotate the blades. They also help to keep out insects and rain. This type of vent is often called a whirlybird vent. They also come in different shapes. The most important thing to remember about these vents is that they need to be located as close to the ridge as possible.

A passive air vent is also a good option. It’s a simple concept that works by facilitating the exchange of warm and cool air. These vents are typically located in the fascia or soffit, and should not be covered with insulation. If they are located in the eaves, they may need to be covered with screening material. The openings should be no more than 1/16 inch.

Besides providing proper ventilation, a finished attic can provide more room. A properly finished attic can also help to reduce the utility bill. It can also help to keep the temperature in the attic stable, thereby preventing ice dams from forming. Ice dams can lead to leaks in the home. They can also damage the roof shingles. In addition, ice dams can lead to mold and mildew, which can cause serious health problems.

There are also passive ventilation options, such as a gable end vent. These vents are installed on the exterior wall of the attic and are made of wood. A gable end vent is also useful for homes with a sloped roof. They are installed using a nail driven through the roof structure to mark the vent location. Most homes have room for this vent.

If you live in a hot climate, you may choose a ventilation system that is a bit more efficient. Depending on the size and complexity of your attic, you may need a powered vent or two. Adding a ridge vent will cost between $400 and $500.
