If you’re like most homeowners, then you’re always looking for ways to lower your power bill. One way to do this is by installing the correct roof vents. There are a variety of roof vents available on the market, and each one has its unique benefits.
These types of vents work to expel hot air and moisture from your attic area and not only makes the home more comfortable to live in, but it also helps to protect your roofing materials from heat damage.
What is a Roof Vent?
A roof vent is part of the ventilation system for your roof. It helps to circulate air which removes moisture and keeps your roof healthy and extends its lifespan. Vents also help improve your home’s energy efficiency by allowing you to control the temperature better inside.
There are several different types of roof vents, and each one has its benefits and drawbacks. In this article, we’ll look at how roof vents work and look at the different types of roof vents, and help you decide which one is right for your home.
How do Roof Vents Work?
Roof vents work by drawing in fresh air from the outside and expelling stale air from the inside. This helps keep your roof healthy by removing moisture and preventing the formation of ice dams. It also helps to improve the energy efficiency of your home and reduce cooling costs in the summertime.
There are several different styles of Ventilation:
Intake Vents
Intake vents are a style of Ventilation that brings fresh air in from the outside. They are typically installed in the roof ridge or eaves and can be categorized as passive Ventilation, as discussed below.
Exhaust Vents
An exhaust kind of Ventilation takes stale air out from the inside and is installed on the roof. They expel air by natural convection or forced Ventilation with fans.
Types of Attic Ventilation Systems
Ventilation is the process of exchanging indoor and outdoor air. There are two main types of ventilation systems:
Active Ventilation systems
These systems use fans to move air in and out of your home. They pull air from the outside and push it into your home, which helps to expel hot air and moisture. Active ventilation systems are ideal for homes with high humidity levels or that experience a lot of weather-related damage.
Passive Ventilation Systems
These systems rely on natural airflow to move air in and out of your home. They work by drawing cool air in through the bottom of your home and expelling hot air out the top. Passive ventilation systems are ideal for homes with low humidity levels or don’t experience much weather-related damage.
Types of Active Roof Vents
Active exhaust vents come in various shapes and sizes, but they all use fans to expel hot air and moisture from your home. The most common types of active roof vents are:
Turbine Vents
The first type of roof vent is the turbine roof vent. These exhaust vents are installed in the roof ridge and use a spinning turbine to move air in and out of your home. They work best in low wind speeds, ideal for homes with multiple stories.
The turbine vents are available in both manual and powered models. The powered model has a built-in fan that helps move air more quickly, while the manual model relies on wind power to spin the turbine.
The main downside of turbine roof vents is that they can be noisy when the fans are running. They also require regular cleaning to keep them from becoming clogged with debris.
Solar Powered Vents
Solar-powered vents are roof vents that use solar power for the fan. They work by converting sunlight into electricity, which then powers the fan. This makes them an excellent option for homes with limited or no access to traditional power sources.
The downside of solar-powered roof vents is that they can be more expensive than other types of roof vents. They also require a fair amount of sunlight to operate, so they may not be ideal for homes located in shady areas.
Power Vents
These circular-shaped exhaust vents use a motor to power the fan. They work by drawing air in through the roof and expelling it out the side of the vent.
They can be installed in either the roof ridge or roof eaves, and they come in both powered and non-powered models. The powered model has a built-in fan that helps move air more quickly, while the non-powered model relies on wind power to spin the turbine.
Power vents are an excellent option for homes with multiple stories, as they can be installed in the roof ridge to provide airflow to all levels of the house. They’re also a good option for homes with high humidity levels, as they help to expel moisture from home.
Power vents can help prevent ice dams from forming on the roof when used in the winter.
The main downside of power vents is that they should be used with a humidistat during the winter months to prevent over-ventilation and damage to roofing materials.
Ridge Vents With a Baffle
The most commonly used roof vents, ridge vents, are installed in the roof ridge and work by drawing air from the soffit vent and expelling it out the ridge.
The ridge vents with a baffle are the best option for many homes since they are not noticed from the ground.
The main downside of ridge vents is that they can allow moisture and pests into your home if they’re not correctly sealed. They also require regular cleaning to keep them from becoming clogged with debris.
Off Ridge Vents
Off ridge vents, another roof vent is installed with three-tab asphalt shingles on the roof peak. The vents extend out and away from the roof, allowing hot air to escape. This type of roof vent is less common than ridge vents but works well in high winds.
They are not as popular as ridge vents because they are not as effective in removing attic heat. They are also smaller in size and can be blocked by snow.
Types of Passive Roof Vents
The Passive roof vents are the roof vents that do not require any power to operate. Instead, they use natural forces, such as wind or gravity to move air in and out of your home.
The most common types of passive roof vents are:
Gable End Vents
Gable vents are roof vents installed in the gable ends of your roof. Mostly come in a triangular shape; these roof vents allow air to flow into and out of your home.
They work by using the wind to create a pressure difference between the inside and outside of your home. This pressure difference causes air to flow into and out of your home, which helps to cool it down during the summer months.
Most Gable vents are made out of wood, and they come in a variety of colors to match the roof of your home.
Static Vents
Another type of passive roof vent is the static roof vent. Static roof vents are roof vents that do not have any moving parts. They are box-shaped roof vents that allow air to flow in and out of your home.
They work by using the wind to create a pressure difference between the inside and outside of your home. This pressure difference causes air to flow into and out of your home, which helps to cool it down during the summer months.
The biggest downside to static roof vents is that they can get clogged with debris over time, which will prevent them from working correctly.
Soffit Vents
One of the most common roof vents is the soffit vent. Soffit vents are installed in the roof’s eave and work to draw cool air into your attic. This type of roof vent is typically made from plastic or metal and can be easily installed by a professional roofer.
There are two types of soffit vents depending on the type of home: Individual soffit vents and continuous soffit vents. Individual soffit vents are best for older homes with smaller roof overhangs. Continuous soffit vents are installed along the entire roof’s eave and are ideal for newer homes.
Ridge Vents Without a Baffle
Very similar to ridge vents but does not have the baffle. They are less common than ridge vents because they can allow moisture and pests into your home if they’re not correctly sealed. They also require regular cleaning to keep them from becoming clogged with debris.
Drip Edge Vents
A drip edge vent is a roof vent that is a part of the drip edge system. It is a small, rectangular-shaped roof vent that helps to draw air into your attic.
Drip edge vents work by using the wind to create a pressure difference between the inside and outside of your home. This pressure difference causes air to flow into and out of your home, which helps to cool it down during the summer months.
Drip edge vents are a newer type of roof vent and are not as common as other roof vents. They are made out of metal and come in various colors to match the roof of your home.
What Are The Benefits of A Roof Vent?
The following are some of the benefits that roof vents can provide to your home:
