What are the Types of Roof Vents? (Active & Passive Roof Ventilation)



What are the Types of Roof Vents? (Active & Passive Roof Ventilation)
Spread the love

You can walk around any neighborhood, look at the roofs, and see different things coming through and/or sitting on the roof. These different roof penetrations all serve a certain purpose to help your roof and home function the way it’s supposed to.

One of the more important penetrations is your roof vents. Roof vents come in different shapes and sizes, but all perform the same function: allowing your home to breathe correctly.

When you get a new roof, you’ll choose what style of vent based on the look you want and the ventilation system your attic has. But what are the different types of roof vents to choose from?

Because we want you to have all the knowledge to make the right purchasing decision for your situation, we’re going to break it down for you.

The team at Bill Ragan Roofing has helped the residents of Nashville with their roof vents and attic ventilation systems since 1990. We work with you to find the right roof vent that fits the look you want while staying on budget. And if there’s ever a problem with a roof vent we install, you’ll have our lifetime warranty to take care of it.

By the end of this article, you’ll learn about attic ventilation systems and the common types of roof vents.

What is attic ventilation?

Your attic’s ventilation is a system that allows your house to breathe. It works by pulling fresh air through your attic and allowing the heat to escape through your vents properly.

There are 2 types of attic ventilation systems: active and passive. Active ventilation pulls the air in from the outside and pushes it out from the inside. Passive ventilation means the air in the attic is moved around by natural sources, such as wind.

Both ventilation systems do their job, and one isn’t better than the other. But if your attic isn’t properly ventilated, it’s going to lead to problems.

What are the types of roof vents?

Now you know what attic ventilation is and the 2 types of ventilation systems. Each system comes with different styles of roof vents to choose from.

The types of active roof vents

Active vents work by creating a drawing effect that pulls the air in with the intake vents and pushes it back out through the exhaust vents. There are 4 common types of active roof vents: turbine, power, ridge, and solar-powered vents.

Turbine vents

Turbine vents (also known as whirlybirds) work by using a drawing effect through convection (heat rising) to move the air in your attic around even when there is no wind.

As long as this type of vent is installed properly, the air in your attic is moved around 10-12 times per hour.

Because turbine vents have slats on them and are open-aired to the attic, there is a misconception that rain, snow, and insects can enter your home through them. However, they’re designed so that none of this occurs unless the vent is damaged.

Power vents 

Powers vents are circular-shaped vents with very low profiles you see on most roofs.

They’re installed near the ridge (top) of the roof and use electricity to pull the hot air from the attic. During the winter, you’ll want to run your power vents with a humidistat.

Otherwise, the humidity will build up in your attic, cause condensation, and shorten your roof’s lifespan. Be aware, power vent motors tend to fail, so be prepared to replace them at some point.

Solar-powered vents 

Solar-powered vents are like power vents, but they use the sun as their power source.

These vents sound great from an energy saver standpoint, but the vent turns off when the solar-powered battery is charging.

The problem is that the solar panel won’t hold a charge long enough to run the vent all day due to the power needed to run the motor. So while the battery is recharging, you may wind up with your air conditioner running more, which will cause your energy bill to go up.

Ridge vents with a baffle 

Ridge vents are cut into the ridge of the roof and run the entire length of it.

This style of vent is popular because they aren’t noticeable from the ground. While they’re extremely popular, the downside to this vent is that if the vent doesn’t have a filter, insects, debris, rain, and snow can enter the attic.

If a ridge vent doesn’t have a baffle (chutes that provide a channel for air to flow) to help move the air through your attic, then it’s a passive vent.

The types of passive roof vents

Passive vents use the natural forces of nature, such as wind and convection, to move the air through your attic. These vents have no moving parts, create no noise, and are virtually maintenance-free.

The common types of passive roof vents are static, ridge vents without a baffle, and gable end vents.

Static vents

Static vents look like little boxes on your roof.

They work by allowing the heat to escape out of the roof through the convection method.

This means as the heat in your attic rises, the hot air is pushed out through the vents. You might also hear static vents called turtle vents or box vents.

Ridge vents without a baffle

Like the active version of this type of roof vent, it’s cut into the ridge and runs the entire length of the ridge. The only difference is that there’s no baffle (chutes that provide a channel for air to flow).

The problem with ridge vents without a baffle is that it allows debris, rain, snow, insects, etc. to enter your attic.

Gable end vents

A gable end vent is a wooden vent installed on the exterior wall of your attic below where the 2 slopes of your roof meet. This vent relies on the wind coming from the outside to move the air in and out of your attic.

Why is attic ventilation important to your roof and home?

Now you know the most common types of roof vents. Which roof vent you choose depends on the look you want and the ventilation system.

If you don’t want to see the vents from the ground, a ridge vent is the right one for you. If you like the way turbine vents look, then go with them.

No matter what kind of roof vent you want, the most important thing is that your attic is properly ventilated. If it’s not, it will lead to a multitude of costly problems and headaches in the future.

That’s why it’s crucial to know why proper attic ventilation is important to not only your roof but also your home. Because it’s so important, we already broke it down for you.

Since 1990, the team at Bill Ragan Roofing has helped homeowners in the Nashville area with everything roofing, including something as important as attic ventilation. That’s why one of the first things we check for during an inspection is proper ventilation. If you’re local to Nashville or a surrounding area, don’t hesitate to contact us to take care of all your roofing and ventilation needs.

The Shock of Chopping Up a Chanel Bag




The Shock of Chopping Up a Chanel Bag
Spread the love

Marina Ermoshkina, a Russian television host, typically fills her Instagram with glamorous selfies: couture clad on red carpets; bikini clad on Riviera beaches; smiling aboard yachts. But last week she decided to express her anger over Chanels new restrictions on sales to Russian nationals, by slicing up her pearl-gray leather shoulder bag worth about $8,000.

In compliance with the European Unions current sanctions against selling luxury goods valued over 300 euros to Russians, Chanel not only closed all its Russian stores but also instituted a policy requesting Russian customers anywhere else in the world to sign a statement promising not to wear any new Chanel purchases within their home country of Russia.

They could buy Chanel in Paris for example, but were asked not to wear it in Moscow or elsewhere in Russia. (Chanel recently clarified that the company was currently working on improving this approach. It also apologized for any misunderstanding this may have caused.)

For her handbag-slicing video, Ms. Ermoshkina appeared to be in a luxury high-rise apartment, with floor-to-ceiling windows revealing the night skyline of an unidentified metropolis.

I am against a brand that supports Russophobia, Ms. Ermoshkina explained in her post. Chanel is just an accessory, an accessory that decided to discriminate against people on the basis of nationality, which I will not tolerate.

In a separate video, Katya Guseva, a D.J., echoed Ms. Ermoshkina. I am against the brand, which supports Russophobia and discrimination against women based on nationality, she said while scissoring through a Chanel hobo. Behind her, a crystal vase of pink peonies sat atop a mirrored vanity table.

Buying guide: Car shift knobs

Choosing the right car shift knob can be tricky with so many on the market. If it doesn’t end up fitting your car’s gear lever or fails to work with an automatic transmission system, your safety will be put at risk. You can’t afford to make a mistake when choosing a car shift knob, especially when it comes to quality and performance. To help you out, we’ve put together a complete buying guide for car shift knobs to help you invest in the ideal product.

The two types of car shift knobs

There are two different kinds of car shift knobs available, and they differ mainly in their appearances and how you’ll grab them when shifting gears. Keep reading to learn the differences between the two.

Ball-shaped car shift knobs

You can probably gather from the name that this kind of car shift knob comes in the form of a small, solid ball. This affords you the freedom to choose between a regular-colored car shift knob (like a black or gray sphere) or something a little more fun and flashy, like a legendary dragon ball design. You won’t have to worry about removing the old gear shaft when installing it, which greatly reduces the total installation time. When you go to shift gears, grab the sphere in your hand and simply pull as needed– it will almost look like a magical orb sitting right there in your car.

Stick-shaped car shift knob

The most common form of car shift knob is the stick-shaped one with its long cylindrical or rod-like body. This car shift knob will act as the shaft, so you’ll have to remove the existing one to install it. The main body of this kind of car shift knob has a cylindrical shape, so you won’t have any problem grabbing the entire knob and changing gears. You can either wrap your fingers around the rod or place your cupped palm at the head for a quick and easy gear change.

Selecting the right car shift knob

Transmission system compatibility

Cars have two types of transmission systems— automatic and manual. Most car shift knobs you’ll find available are designed with the sole aim of fitting a manual transmission gear lever. If you buy such a product, you won’t be able to use it with an automatic system or a manual transmission system with a button. Usability is quite restricted, and this can cause considerable problems if you want to use the same car shift knob for different vehicle types. If you need a versatile product, look for a car shift knob that will suit both manual and automatic transmission systems.


Most car shift knobs serve as a gear-changing rod and decorative element for your car, so you’ll need to ensure that the chosen product complements your car’s interior or even creates a dramatic look. If your car’s interior has a black shade, getting a black or gray car shift knob will help you match your vehicle’s aesthetic and create a perfect balance in tones. A bright orange car shift knob for your car’s beige or gray interior will create a contrasting ambiance, so your color choice will ultimately depend on the desired look of your vehicle.


Car shift knobs come in many designs– some are large open structures while others are simple, transparent rods. If you want to keep your vehicle’s interior looking classy and straightforward, go for a smooth and plain design, like a pen or ball. If you instead want to make a statement with your vehicle, though, look for a product with a completely unusual and unique design, like that of a samurai katana sword or a dragon ball.


Before you finalize your car shift knob choice, make sure to check the quality of its grip, since you’ll need to maintain superior control while changing gears. Fabric-covered shafts usually increase the friction between your skin and the rod’s surface, meaning you won’t have to worry about your hand slipping down and interfering with your control while shifting. You should also choose a product with smooth edges and corners so that your palm and fingers stay safe.


You’ll have to connect your car shift knob to the gear lever using an adapter. Most products usually come with three or four adapters of various sizes so that you can fit the car shift knob to various gear systems and car models. If you have an SUV, a sedan and a truck, look for a car shift knob with adapters that will fit the gear levers of all your vehicles.


It’s crucial to check the materials a particular car shift knob is made of. No matter the design or color you’ve selected, ensure that the product’s core is made from alloy, acrylic, or aluminum. These three materials are highly durable, strong and can sustain collisions or impacts, and you won’t have to replace the car shift knob too often. Apart from this, if your chosen car shift knob has a cover around its cylindrical frame, check its material. Silk is mainly used in the katana sword shafts, and a material like this offers maximum comfort.

How much do car shift knobs cost?

Car shift knobs come in different shapes, designs, and color combinations, which is why the average price can vary, although most fall between $16.99 and $23.00. If you compare car shift knobs based on materials, acrylic knobs will be more expensive than alloy ones. Universal car shift knobs that work with both automatic and manual transmission systems will also be more expensive than those without a universal fit.

How to install a car shift knob

For installing a car shift knob to your gear system, follow the steps below:

  1. Detach the existing shaft by taking out the screws
  2. Clean the lever head and remove any residue from oil or grime
  3. Once done, check which adapter has a snug fit around the lever
  4. Attach it correctly and make sure it’s secured
  5. After this, place the narrow, threaded end of the car shift knob and turn it to tighten the attachment
  6. Use the metal inserts to secure the entire shaft on the gear lever
