Roof Vents ,What types and styles of roof vents are there 

When you build a home or are looking at making your home more energy-efficient, you need to look at the type of vents you have on your roof. The vents on your roof have a purpose for being there, and you will need to do your homework to ensure the type and style you have or want is the right thing for your home.

The right type of roof vent will help keep your home cool and moisture-free. You will also extend the life of your roof and help your family stay cool during the summer and warm in the winter. A Roof vent is part of a well functioning home and should be taken into account when putting a new roof on the house.

A Roof vent is an integral part of your home. For most types, you do not need to think much about them, but others come with electronics or timers you can set for convenience. There are multiple types of vents to install, and often a single roof will have more than one type depending on what needs venting and the design of your house.

What is a roof vent?

Whether a company builds your home or you build it yourself, every home will need at least one roof vent. A roof vent helps your home to breathe during all seasons and is requirements for home building codes everywhere. There are two purposes for roof vents found in most homes.

Exhaust vents

Installing exhaust vents help your home to release built-up heat. They install near the ridges of the roof. Made from a mold with the high-impact copolymer, they install underneath the last layer of shingles on your roof. The vents run close to the roof and are almost invisible.


Intake Vents

Intake vents allow for air to filter into your home. They install near the edges of the roof near the eaves underneath the last layer of shingles on the roof. The intake vents take in cool air around the attic, which forces out any trapped warm air through the vents installed along the ridge of the house.

Why do homes need roof vents?

When you are building a home, a roof vent provides your home with longevity. They also help to

Internal temperature control

Having vents on your roof can provide your home with a way to breathe. This can be extremely important in the summer and winter months when second or third story homes increase or decrease substantially in temperature. The greater the temperature variation for these homes, the greater likelihood there is poor ventilation


Reduce Energy Costs

Having a home that properly vents into and out of your home is something you need to extend the life of your heating and cooling appliances. They also help to reduce your energy bills because your home is running more energy efficient. The less you run your air conditioner or heater, the better your bill will begin to look.


Extend the life of the roof on your home

Temperature changes inside and outside your home will wear your roof out. Proper ventilation helps to prevent this from happening so quickly. In the winter, ice can build up on your roof, causing damage if there are no vents to direct the warm air of your home up to the roof. It also allows for more ice buildup on the edges of your roof, which damages gutters and the under layers of your roof.

With proper ventilation, warm air can escape your home, preventing the buildup of ice during the winter and the buildup of moisture during the summer months. During the summer, the buildup of moisture in your attic spaces and eaves can cause the growth of molds and bacteria as well as encourage the wood in your home to rot.

How does a Roof Vent Work?

The propose of most types of vents is to let the trapped hot air and moisture in your attic or eaves out of your roof. There are different types with each type providing your roof with different types of ventilation.


Static Roof Vent

A static roof vent does not require electricity and is perfect low-maintenance vents. They are passive vents that let the moisture and heat of your attic and roof out. They are easy to install around your roof without requiring any other vents.


Moving Roof Vent

Moving vents also do not require electricity, but they do rotate with the movement of the air to help filer hot, moist air out and cool air into your roof. They are mini wind turbines that are easy to recognize on a roof. They are ideal for windy areas, though, on still days, you will receive no airflow. They also tend to squeak in the breeze if not clean and lubricated.


Electrical Roof Vent

An electric roof vent connects to your home's electricity and runs whenever you want them too. You can set them on timers and help reduce the heat and moisture in your attic or eves. This type of vent is good to install in areas where heat and moisture are frequent throughout the year.


Solar Roof Vent

Solar vents are some of the latest types of ventilation to help your home remain cool and moisture-free. They use the sun from a solar panel installed on top of the vent. They are perfect for homes that receive a lot of sun exposure.

What types and styles of roof vents are there?

The size of your home will determine the types and styles of roof vents that work the best for your home, the number of floors and the layout of your heating and cooling ducts.


Box Vents

A box vent is a low profile vent. You install it, and it sits close to the surface of the roof to help let the hot rising air escape. They do not have any moving parts, and you install them as close as your roof as you can to the surface of the roof to help release the hottest hair. You install them over a hole in the roof with either a metal or a plastic covering.


Wind Turbine Vents

Wind turbine vents turn with the wind that blows. They do not require motors and are purely wind-driven to help warm air get forced out of your home or to let cool air in. They allow for a greater amount of airflow than other types of vents and help to prevent the buildup of moisture in places like your attic.

Wind turbines wear out more quickly if not maintained. They have moving parts that require lubrication, and if not properly cleaned and maintained, then the spinning mechanism can jam with large amounts of snow or other plant life that ends up on the roof.


Power Vents

Power vents require electricity to run and use a large fan to push hot air and moisture out of the upper stories of your home or attic. They blend well with your roof and are extremely handy for those hot days or the days. Many power vents come with thermostats so you can adjust the temperature of your home to the ideal levels.

You can use the temperature settings to help program your power vents to turn on when the temperature reaches a certain level. This is a good thing for those hot or cold days when you aren't at home to set the system yourself. Some systems also come with humidistats that will turn on when the humidity of your upper stories or attic reaches a certain degree of humidity.

Most power vents connect directly to your home electrical system and run on the grid, like any other electronic in your home, but some of the latest versions can have solar panels to run them off the sun. Because they are solar-run, they will run more quietly than older vents. The problem with having such a quiet system is that if they break down, you are less likely to know they are broken.


Ridge Vents

Ridge vents are a type of static roof vent. They do not move, and unlike box vents, they are very long and run along the ridge of your house. They provide venting along the length of your roof, allowing for heat to escape your home as it rises. Roof vents are attractive to a lot of homeowners because they are not visible to the casual observer.

Because ridge vents are flush with your roof, they let a lot of hot air and moisture escape from your attics and upper stories. They are very efficient because they do not help create temperature changes in your attic, such as other types of venting that often create hot or cold spots in your attic. They are a good type of venting to add to your roof because they do a lot to extend the life of your roof.


Off Ridge Vents

Off Ridge, Vents look a lot like box vents and function a lot like box vents. They are another type of static vent that you install over the holes cut in your roof for ventilation. They are longer than box vents and a lot thinner. They are not as effective as other types of vents, but they do their job to reduce the amount of moisture and to help hot air exit from your attic or upper stories.


Cupola Vents

Cupola Vents are sometimes not vents at all. They look like vents for some homes as they are a type of decorative vent that sits on the tip of the highest ridges of the house. They can function as a vent to allow moisture and hot air to escape your attic, but they are not the primary way to help your home breathe, and additional vents will accompany their installation.


Soffit Vents

Soffit vents help your eaves to breathe. You will see the attached near the sides of your roof and will be aluminum or PVC. They can help vent out a lot of the hot air and moisture that builds up in the eaves of your home. You will see them installed on homes where vents are unusually small for full breathability of your upper stories.


Green House Vents

Greenhouse vents are for greenhouses only. They fully open up to expose the greenhouse to the sun and the rain. They have manually opened vents that allow you to control the level of humidity and temperature. They are larger than the average vent and require you to open and close them as the needs of the greenhouse require.

Final Thoughts

Building or upgrading your home vents can have a great impact on the lifespan of your roof and your home. Having a well-designed roof with the proper vents will help your home stay cool in the summer and warm in the winter. The different vent designs are box, wind turbines, power, ridge, off the ridge, cupola, soffit, and greenhouse vents with each vent type having its benefits for your home.

The right type of vent might be a combination of vents, depending on the design, as well as the added features. They can be static vents you do not need to think about or electric vents you can program using in-home electronics or specialty apps. Your choice of ventilation for your home will work to help make your home more energy-efficient and temperature controlled.

Choosing the right type of ventilation might be as easy as getting on your roof, and seeing what is already there, you can also consult a professional to see if you can get your heating and cooling costs down. You can also do your homework and look at more updated options for keeping your home temperature-controlled and efficiently, such as using solar-powered vents.
