One of the most important decisions you’ll make is what type of vents to use when it comes to roofing. A few different types of vents can be used on a roof, and each has its benefits and drawbacks. Here are different types of vents that can be used on a roof.
Smoke Vent
A smoke vent prevents smoke from entering the home during a fire. This is an important function for smoke vents, as smoke inhalation can suffocate homeowners and cause injury or death. Smoke vents are made of metal and usually allow warm air to escape through the opening. A smoke vent is typically located at the highest point of the roofline near the chimney.
Ridge Vent
Ridge vents are one of the most popular vents used on a roof. They are installed along the roof ridge and allow air to flow in and out of the attic. Ridge vents are effective at cooling the attic and reducing moisture accumulation. Ridge vents are also very easy to install.
Soffit Vents
Soffit vents are installed in the roof’s soffit and allow air to flow into the attic. They are effective at cooling the attic and reducing moisture accumulation. Soffit vents can also be used to exhaust warm air from the attic. Soffit vents are relatively easy to install, but they can be susceptible to wind damage.
Gable Vents
Gable vents are installed in the roof’s gables and allow air to flow into and out of the attic. Gable vents are effective at cooling the attic and reducing moisture accumulation. Gable vents are also very easy to install. Gable vents can sometimes cause problems during heavy rainfall as it is possible for water to enter the attic.
Louvered Vents
Louvered vents are installed under the roof’s soffit and have slats that open and close to allow air into the attic. They are considered a passive venting system because they depend on the wind to open and close the louvers.
Louvered vents are effective at cooling the attic and reducing moisture accumulation. These vents have automatic window openers that are critical during summer or when it’s hot. They are also very easy to install, but they can be susceptible to wind damage.
Solar Powered Roof Vents
Solar-powered roof vents use a solar panel to draw air out of the attic through a fan to cool the attic. These types of roof vents have been used to reduce energy consumption in homes by drawing hot air from the attic during warm months, which reduces reliance on central cooling systems.
However, passive airflow from these fans is not typically powerful enough for venting moist air from an unconditioned attic during cold months when humidity levels are high because water does not readily condense into warm air.
Ridge Vents with Powered Attic Ventilators (Kool Vents)
Ridge vents with powered attic ventilators are installed along the roof’s ridge and have a solar panel to draw air out of the attic through an exhaust fan to cool the attic. These types of roof vents have been used to reduce energy consumption in homes by drawing hot air from the attic during warm months, which reduces reliance on central cooling systems.
However, passive airflow from these fans is not typically powerful enough for venting moist air from an unconditioned attic during cold months when humidity levels are high because water does not readily condense into warm air.
Atmospheric Vents
Atmospheric vents are installed on the roof and allow air to flow into and out of the attic. They do not require any electricity, and they effectively cool the attic and reduce moisture accumulation. Atmospheric vents can be installed in various ways, including through the use of fans, turbines, or wind-powered generators.
Power Roof Ventilators
Power roof ventilators are installed on the roof and use a motor to draw air out of the attic through an exhaust fan to cool the attic. These roof vents are typically used in commercial buildings where there is a greater need for ventilation. Power roof ventilators can effectively cool the attic and reduce moisture accumulation, but they require electricity to operate.
Automatic Roof Vents
Automatic roof vents are installed on the roof and use a sensor to detect when the attic reaches a certain temperature or humidity level. When the attic reaches this temperature or humidity level, the automatic roof vents will open to allow air to flow into and out of the attic.
Automatic roof vents are effective at cooling the attic and reducing moisture accumulation. They are also very easy to install, but they can be susceptible to wind damage.
Wind Turbine Vents
Wind turbine vents are installed on the roof and use a spinning turbine to draw air out of the attic through an exhaust fan to cool the attic. These types of roof vents have been used to reduce energy consumption in homes by drawing hot air from the attic during warm months, which reduces reliance on central cooling systems. Wind turbine vents effectively cool the attic and reduce moisture accumulation, but they require wind to operate.
Conclusion
Roof vents are designed to draw air into or out of the attic to cool the home during warm months, reduce energy consumption by drawing hot air from the attic during warm months, and reduce moisture accumulation. The type of roof vent used depends on the home’s climate because different types of roof vents perform better under specific conditions.
