Roof exhaust vents remove heat and moisture from the attic during the summer. In addition to removing moist damp air during the winter. This benefits the attic because it will keep dry insulation. Dry insulation prevents mold and mildew from growing.
In order for roof exhaust vents to work efficiently, they must be near the peak of the roof. This is because hot air rises and will naturally collect near the peak.
There are many roof exhaust vents to choose from, and choosing the right one may seem difficult. After all, not all roofs are the same. This is why AVP offers to assist all customers with their roof vent choices.
All roof vents are customizable. Choose your color, diameter, height, curb mount flange and/or tailpiece adapter for duct systems.
Vents for a flat roof tend to be built differently than vents for a steep roofs. The main difference is the height of the vent. Vents for a flat roof need to be built taller. AVP offers vents for both roof types. For more information on roof exhaust vents for flat roof applications please click on: Aura Vents, Aura Vents with Curb Mount Flanges, Round Back Vents with Curb Mount Flanges, Keepa Vents and Witches Hat Vents.
In order to achieve proper attic ventilation, there needs to be a balance between Exhaust and Intake Air. The intake of air will allow the hot humid air to escape through the exhaust vents at the peak. Air intake vents are available for both flat roof and pitched roof ventilation. Roof Vents can also be made with a curb mount flange for installation on roof curbs.
The Aura Attic Fan exhausts air for proper attic ventilation. This fan will exhaust air continuously even when the motor is off. It also works passively because of the Venturi Effect. This occurs when the wind blows against the outer louver to create an upward draft. As a result, allowing air to freely flow in and out. Aura Attic Fans remove hot humid air during the summer and moist damp air during the winter. This not only keeps the insulation dry but will lengthen the life of the roof.

Proper attic ventilation is important during the winter. Without it, moisture can get trapped in the roofing system which could cause decay of the structure. To achieve proper attic ventilation, you need both exhaust vents and air intake vents. This will remove excess radiant heat and moisture from the attic. Maintaining proper attic temperatures will ultimately lower energy costs.
Every roof should have exhaust vents along the peak and air intake vents towards the bottom. AVP supplies both exhaust vents and soffit vents for under-eave ventilation.
Having roof vents for air intake and air exhaust can alleviate all of these problems. Roof vents are fairly inexpensive but can have a profoundly positive impact on your home or building. For most people, owning a home is the biggest investment they will make. Therefore, venting your home is not only important, but it also makes it a healthier and a more energy efficient place to live.
In May of 2019, AVP’s president, Martin Kolt, began shooting informational roof vent videos. The goal is to help answer frequently asked questions about roof vents. In addition, these videos also support other technicians out in the field. It’s important that Martin shares his knowledge with AVP’s customers. After all, he has been supporting the roof ventilation industry for over 30 years.
At work, Martin and his team engineer better roof vent designs and also find new and innovative ways to help the end-user. He has discovered ways to manufacture vents more efficiently and safely for his team.
When Martin is not working on roof vent designs, he acts as corporate liaison with Underwriters Laboratories (UL), Texas Department of Insurance, and Florida State. Martin and Ethan plan to release more videos later this year. The goal is to create a video library of valuable information that will be easily accessible. Their videos are available for viewing on AVP’s website, Facebook and AVP’s YouTube channel.
AVP's roof vents vary in size from 3 inches in diameter to 48 inches. While on the other hand, the collar heights range from 1 inch to 12 inches. As a result, ensuring each customer to find a roof vent to fit their home. Some roof types may be EPDM, TPO, PVC, asphalt shingle, cedar shake, slate, or tile. AVP serves the residential, commercial, and industrial roofing sectors.
Exhaust Roof Vents remove hot air from the attic in the summer and moisture in the winter. Attic Ventilation will extend the life of your roof and can make your home or building more energy efficient. AVP forms roof vents out of heavy gauge aluminum so they can hold up to the toughest weather conditions. Roof Exhaust Vents are manufactured to handle different climate zones. Roof pitch is a factor when deciding which roof vent to purchase.
AVP’s Roof vents have the option of over 40 powder coating colors to choose from. Powder Coating lasts longer than conventional wet paint. How do you powder coat roof vents? First, roof vents get a coating of a special magnetic paint powder. Then the roof vents go into an industrial oven at 400 Degrees Fahrenheit for 15 minutes. The baking process melts the paint powder giving the roof vent a fresh look. Once the roof vent cools, the paint cures and hardens. As a result, this process makes the vents look new for longer than other painting methods.

Attic ventilation is important as it can help maintain the health of the building. Removing excess heat in the summer and moisture in the winter will help the life of the roof. As a result, this will also help the functionality and efficiency of the HVAC systems. Flat roofs are anything under a 3/12 pitch. Here at AVP, we design our vents specifically for low slope or flat roofs.
These vents typically have a taller collar and/or come with a curb mount flange for installation on roof curbs. The additional height prevents precipitation from entering inside these static vents. In addition, this will protect the attic from moisture.
This vent can be an air intake vent as well as an air exhaust vent. If it's on the upper portion of the roof, this vent can be used as an exhaust vent. This vent will allow heat and moisture to escape. However, when on the lower end of the roof it can be used as an air intake vent similarly to a soffit vent.
Off-ridge static roof vents are also excellent for ventilating parapet walls because it will allow the buildup of heat and moisture within the wall to escape. Above all, the Universal Vent is ideal for proper attic ventilation.
The 1/8 inch opening between the louvers will keep out precipitation and wildlife while allowing air to move freely. In addition to its functionality, it has a low-profile design.

These vents are UL listed, and meet the standards of the Texas Department of Insurance, Florida State and have CAL FIRE approval. Need more convincing? See AVP's testimonials to see what customers are saying.
In order to exhaust air, you need a fresh air intake. Roof Louvers and Static Vents that intake fresh air to the attic allow exhaust vents to work efficiently. This pressurizes the space so that there is air available to flush out. As a result, excess heat can escape through the exhaust vents. All commercial air intake roof vents have a vertical height requirement for flat roof ventilation.
As a result, AVP's vents can also be made with a curb mount flange. Curb mount flanges are only necessary if going onto roof curbs. Roof vents can be made to connect to a duct with a tailpiece adapter if connecting to a duct system. Above all, AVP's roof vents have an aluminum construction; therefore they will not rust.
AVP's Intake Soffit Vents made are with a Multi Louver Design for optimal fresh air intake.
They are essential for proper attic ventilation. In order to exhaust heat from your roof, you need a soffit vent to bring in the cool dry air. The Under Eave Vent is an air intake roof vent. To clarify, Soffit Vents are roof vents that go underneath the eaves of a roof that extend the warm wall line. When properly combined with other roof ventilation devices, soffit vents allow fresh air to enter into an attic to create proper airflow.
At first, it may seem odd to add insulation for warmth then purposely allow cold air to enter the attic through soffit vents. On the contrary, attic ventilation is the key to an energy-efficient home.
As a result, this prevents mold from growing and keeps the insulation dry. In addition to intake air, you will also need to exhaust out the stale air from the attic. See our Exhaust Vents to complete your attic ventilation.
Above all, AVP's all-aluminum Under Eave Vents are corrosion-resistant and easy to install. All vents are available in a wide variety of colors. The 1/8 inch louvers will prevent rain, snow, insects, and animals from entering inside the vent. As a result, allowing the air to move through the vent without resistance.

While on the other hand, the passive air intake caps allow for fresh air to enter the PVC Pipe. They will continually exhaust air with no moving parts while preventing rain and snow from entering. Additionally, the vertical louvers keep out insects and animals allowing for optimal airflow. To add to to that, the round design is aerodynamic to withstand wind speeds up to 200 mph.
AVP offers quality attic exhaust fans that provide airflow for optimal ventilation. The fans remove hot humid air during the summer and moist damp air during the winter. As a result, this not only keeps the insulation dry but will lengthen the life of the roof. All fans have vertical louvers that prevent rain and snow from entering. In addition, these louvers also keep out insects and animals. As a result, this keeps the fan clean which allows maximum air exhaustion without resistance. Additionally, this fan has a removable top which makes it easy for maintenance on the unit. The curb mount flange is only for installation on roof curbs.
The Round Back Solar Fan uses sun light to power it's fan. The strong fan efficiently removes hot attic air all day long. The Round Back Solar Fan also exhausts air continuously even when there is no sun which is during cloudy days and evenings. Like a static vent, it works passively because of the Stack Effect, which occurs when hot air rises it speeds up and flows freely out of the attic.
This exhaust fan works best if it's near the peak of the roof and in direct sun light. It removes hot humid air during the summer and moisture in the winter. See the Climate Zone Chart to determine the proper collar height for installation in your area.
The Aura Solar Fan uses both solar and wind to power the ventilator. It exhausts air continuously even when there is no sun and the motor is off. It works passively because of the Venturi Effect. When the wind blows against the outer louvers this creates an upward draft which allows air to freely flow in and out of the vent.
The 1/8 inch louvers will prevent rain, snow, insects and animals from entering inside the fan.
This Solar Fan comes in an array of diameters and collar heights allowing for installation in any climate zone. See the Climate Zone Chart to determine the proper collar height for installation in your area. See AVP's roof curbs to find one to fit your AVP attic fan.
The goal of roof ventilation is to provide a means of allowing outside air to enter and exit attics and ventilated spaces, so that heat and moisture can leave the building envelope.
A roof vent is an engineered structure that is typically rigid and has two primary functions. First, to allow air to travel through it. And second, to prevent insects, precipitation and any wind-blown debris from passing through it.
Roof vents are for the purpose of air intake and air exhaust. Having vents of both types is a requirement by IBC International Building Code for steep slope roofs.
Air intake vents are used to allow outside air to enter into attics. Intake vents should be located low on the roof, or along the lowest eave or soffit of the roof assembly. Intake vents are best when used in conjunction with roof exhaust vents.
Another way to avoid an obstruction is to install baffles. Baffles go between rafters keeping insulation from blocking air from the soffit vent below. original image
Above all, intake vents will complete attic ventilation; In addition to preventing precipitation, animals and insects from entering the attic space.
NRCA does not recommend the use of drip edge vents as intake vents in northern climates where there is a likelihood of ice damming.
Proper roof ventilation consists of air intake at low points and air exhaust on the high points of the roof. This design system works off of nature’s thermal dynamic, a process called Diurnal Convection. original image
Below are some common types of roof exhaust vents:
AVP's Static Vents are roof vents that do not have moving parts. Therefore, they can be an exhaust vent as well as an intake vent. This will depend on the placement of the vent upon the roof. If the vent is on the upper portion of the roof, it will be an exhaust vent. While on the other hand, if it's on the lower portion of the roof, it would then be an intake vent. AVP's most popular static vents are the gravity vents and the round back vents. Below are pictures of common static roof vents also called passive roof vents and gravity roof vents. original image
Turbine vents rely on wind to rotate the turbine’s fan blades. The spinning of the blades rotate to keep out rain and snow, not to expedite the ventilation capacity as many people believe. (Source: NRCA)
The typical whirlybird turbine vent will rust and stop working overtime. While on the other hand, our gravity vents continuously work without any moving parts.
