Roof vents play a significant role in controlling the temperature and comfort of your home and preventing moisture buildup in your attic. Preventing the buildup of hot and humid air during the summer months in Georgia is especially important, as a lack of ventilation can cause your AC system to work harder than necessary.
Roof ventilation is intentionally designed based on the principles of thermodynamics, or more specifically that hot air rises. That’s why your roof is equipped with two types of vents:
The location of each type of vent is strategic. Placing an intake vent below the exhaust vent allows the cool air that enters the attic to push the hot air out of the attic through the exhaust vent.
There are several advantages to installing proper roof ventilation in your home. They can:
Ice dam prevention is most important in places where snow is a common occurrence. If a roof is improperly ventilated the combination of attic heat and the sun causes snow on roofs to rapidly melt and run off to the roof’s edge where it’s colder. It then refreezes and expands, which forces ice up underneath shingles.
There are several types of roof vents. These vents are generally installed when roofs are being built on new homes, but they may need to be replaced during reroofing or modified to improve attic ventilation on an existing roof. Not every roof vent may be right for your home. An experienced roofing specialist can explain the optimal ventilation for your roof if you ever need a new roof Installed.
As the name suggests, ridge vents sit on the very top of your roof. They span the entire ridge of your roof, making them a great option for removing substantial amounts of hot air from your home’s attic. When combined with intake vents, ridge vents are an excellent choice for vertical roof ventilation.
These types of vents sit close to the ridge of your roof instead of on it. Due to their location, off ridge vents are not as effective as ridge vents. They also tend to be smaller than ridge vents, which means they don’t expel as much hot air. Off ridge vents are a suitable alternative for roofs that don’t have a big enough ridge line to fit ridge vents.
Roof turbines rely heavily on the weather to do their job. A roof turbine won’t spin unless the wind is blowing at least five or six miles per hour. This means it won’t work on days where there’s only a slight breeze or no breeze at all.
Roof turbines are not always as effective as other types of exhaust vents, but since they don’t need electricity to work, they are relatively inexpensive and environmentally friendly.
Soffit vents are installed right underneath your home’s roof line, also known as the roof overhang. Most soffit vents contain small holes through which cool air enters your attic. The intake of air in low sections of an attic helps push the hot air up and out through the exhaust vent.
Gable vents are horizontal vents that use cross-ventilation to keep the cool air moving from one side of the attic to the other. Gable vents usually go hand in hand with gable roofs and are installed on both sides of the home. It’s not recommended to combine gable vents with vertical vents, like soffit vents, because they will likely reduce or cancel out the benefits of the latter.
Fascia vents are installed directly over the fascia board. Fascia vents are a discreet intake ventilation option because they are hidden by roofing materials and gutters. Fascia vents are a good option for homes where soffit or gable vents cannot be installed.
