It’s difficult to know which roof exhaust vent type is best for your home when there are so many options available. In this article, you will get to learn about the different types of roof vents.
How Does Roof Ventilation Work?
In order to avoid condensation in your attic due to overheating, proper attic roof ventilation is essential. An attic or roof space must be ventilated to work, and the two most common ways to do so are:
Natural Types of Roof Exhaust Vents: Natural roof ventilation is used at various places wherever it is suitable. The Air is naturally distributed by the stack effect and the wind effect.
Mechanical Types of Roof Exhaust Vents: In order to generate airflow, a power source is required. Attic pressure rises due to the stack effect, which occurs when warm air rises and creates more pressure. Exhaust is the term for the hot air that exits. Despite this, the hot air can’t be expelled unless there is a way for cooler, lower-pressure air to enter.
As a result of this, your intake and exhaust volume will both be increased by the wind on the outside of your roof. The natural flow of air is created by the combination of intake and exhaust In a properly ventilated attic.

2 Types of Attic Ventilation
Each home’s roof ventilation system is unique, and the best types of roof exhaust vents for your home will be determined by your home’s design and airflow.
When it comes to venting your roof, other things to keep in mind are the climate in your region, local building codes, and the design of your ceiling and roof. Types of roof exhaust vents are divided into two main types that are as follows:
1. Exhaust Ventilation
It is a Ventilation through the exhaust pipe. When it comes to venting your attic, you want to get rid of the hot air because it is full of moisture. Mildew and mould growth can occur if hot air is allowed to sit stagnantly.
Indeed, proper types of roof exhaust vents are essential for this very reason. Allowing this hot air to exit your attic is the job of exhaust air vents. The ridge vent is the most common exhaust vent installed near the peak of your roof. Even though they let the hot, humid, stale, moist air out of your house, they are only half of a great roof venting strategy.
2. Roof Intake Vents
Your roof’s health and longevity depend on ensuring that hot air exits your attic space but making sure it does isn’t always straightforward. In order for the hot air to leave, some sort of bouncer is necessary.

Intake vents are installed at the lower part of your roofline to allow this cool air to enter the attic. Intake ventilation aids in the removal of hot air by bringing in cool air over the hot. Exhaust and intake vents should work together in a symbiotic relationship in a perfect world.

7 Types of Roof Vents
In terms of types of roof exhaust vents, the following are the most common options.
1. Hip Vents:
The hip roof vent is similar to ridge vents in design. A ridge vent is not necessary because these roofs are shaped like a pyramid and are steep enough that they don’t need one. After installing shingles over the hip seams, a hip vent is installed. Aesthetically pleasing while still being highly functional, they are a stealthy addition to any office environment.
2. Ridge Vents:
Ridge vents are the newest innovation in roof ventilation technology, and they’ve quickly taken over as the most popular exhaust roof ventilation option for contemporary roofing styles. This is most likely the type of vent system you’ll have installed if you’re replacing your roof.
It is Invisible to the naked eye, these vents are designed to be installed at the peak of a roof slope. Ridge vents are a little more expensive, but they distribute air evenly rather than venting only certain sections.
Consequently, when properly installed, they are one of the most efficient roof ventilation options, which can offset the high upfront cost. Ridge vents and soffit intake venting are commonly used together to achieve the best results.

3. Off-Ridge Vents:
It’s a lesser-known option to use off-ridge venting. They work in a manner similar to box vents and must be installed in a cutout near the ridge of the roof. The long, thin shape of these vents makes them ideal for removing hot, humid air from your attic. Using these vents in larger attics is not recommended due to their inefficiency.
4. Power Vents:
Electric-powered attic vents are another name for power vents, which, as the name suggests, run on electricity. A wide variety of colors and sizes are available for your roof or gable. These vents are small, round, and low-profile in design. The motor in a power vent turns a fan that pushes hot air out of the attic, reducing humidity. Some power vents come in two varieties:
Your home is directly wired to a thermostat/humidistat to control the operation of hardwired roof vents, which are the most common type of roof ventilation. They have the ability to move a significant amount of air while operating quietly and efficiently.
As opposed to being hardwired, these roof vents are powered by the sun via a solar panel attached to the mount. For roofs that are exposed to a lot of sunlight throughout the day, they are ideal.

5. Wind Turbine Vents:
In addition to being referred to as whirlybirds, wind turbine roof vents date back hundreds of years. You’ve probably seen them in older homes or apartment complexes. The only way these roof vents work is by moving air, not electricity. Due to the spinning of the wind turbine, it pulls hot, humid, stale air out of your attic space and naturally cools it with natural convection.
If you live in an area where the wind is common, wind turbines are the best option for you. Although the vent is effective at speeds of up to 5 mph, this is not a requirement. Both the price and the lifespan of these vents are excellent.
6. Box Vents:
Box vents, in addition to ridge vents, are frequently used for exhaust roof venting. They have a box-like shape and are installed in a hole in the roof, as their name suggests. Your roof may require multiple box vents depending on the size of your home.
This type of vent is ideal for open attic plans because it can be used in conjunction with a soffit vent. Box vents have the advantage of being able to match the color of your shingles, making them less noticeable.

7. Cupola Vents:
To ensure a steady supply of fresh air, cupola vents are positioned at the ridge of a roof.
They are more common on barns, sheds, and other outbuildings rather than homes. They can be expensive, with some clocking in at more than $1,000 for a single cupola vent.
3 Types of Roof Intake Vents
Intake vents function best with other forms of ventilation. They are designed to draw in the fresh air and circulate it through a second system that cools the area. These are some of the most common roof vents that allow for air infiltration:
1. Soffit Vents:
Underneath a roof’s eave or peak, a soffit exhaust vent is an unusual type of vent that must be installed with care. They are constructed of a material that allows humid air to escape. They perform best with a combination of a soffit vent and an exhaust roof vent. It doesn’t matter if these vents don’t save you money, but they do help your air conditioner run more efficiently.
2. Fascia Vents:
Because hip roofs lack much of an edge or eaves to attach to any other type of intake vent, fascia vents are the best option. Hip vents are the ideal complement to these. Although the installation may be different, the ridge vent and soffit vent systems function in the same way.

3. Drip-Edge Vents:
Soffit vents work similarly to drip-edge vents, but soffit vents cannot be installed under the eaves of every home. Drip-edge vents can help with this. Intake ventilation is provided by mounting these vents on the drip edge of a roof. For maximum airflow, they’re equipped with a mesh design.
However, when paired with a vent that exhausts the air, these vents are at their most powerful. It’s important to keep in mind that there may not be a clear-cut right or wrong solution when it comes to roof vents. In some cases, what works for your neighbor’s attic may not work for yours, and vice versa.
What is already installed in your attic will ultimately determine the best roof vent configuration. It may also be a matter of personal preference rather than a specific need.
What Are the Benefits of a Properly Ventilated Attic for Your Roof?

- To cool the second and third floors of your house (if applicable), your overtaxed HVAC systems must work even harder.
- The attic has a lot of moisture (in the form of warm air) in it.
- If you live in a colder climate, you’re more likely to see ice dams during the winter months.
