Do Ridge Vents Help Cool The House?

Ridge vents are small, rectangular-shaped vents that sit atop the roof.

These ventilators help to ensure that your home is well ventilated and cool by drawing hot air out of your attic.

Ridge vents work with soffit and gable vents, which you may find on either side of the roofline.

Roofing experts recommend installing ridge vents when replacing an old or damaged roof. This is because they offer continuous ventilation without interruption.

Do Ridge Vents Help Cool The House?

It depends on where you live, how big your roof is, and what kind of ridge vent you have.

Ridge vents are half-moon-shaped vents that you can place at the high point of a roof or ceiling. Ridge vents help to provide ventilation and reduce heat in your attic.

If you have a ridge vent, warm air will rise out of your house when it’s functioning well. This will cool down the outside air. This then reduces how hot it feels inside your home.

Does A Ridge Vent Make A Difference?

Yes! Ridge vents allow air to move through your attic and out of the top of your home.

This can help avoid common problems with airflow in your attic, such as moisture buildup caused by poor ventilation.

The ridge vent is an effective ventilation solution in some homes. The ridge vents are usually installed at the roof’s peak, allowing air to escape from the attic.

They can help reduce moisture and heat buildup problems in your attic, but they shouldn’t replace other insulation and ventilation options that work better for your home.

Ridge vents can be very helpful for homeowners who don’t currently have adequate airflow through their attic and into their rooftop.

(The open space between a home’s ceiling/roof and its exterior weatherproofing).

Ridge vents may also help reduce water leakage through this area by ventilating any moisture out of the home before it leaks down to vulnerable spots like wood beams or insulation.

Ridge vents are also an effective ventilation solution for homes with low rooflines, where other attic vents may not be readily visible or capable of providing sufficient airflow.

Because of the angled design of most ridge vent products, they usually cannot provide any real protection against rainfall once installed.

That means that if your home’s roofing is already experiencing problems because of excess moisture after heavy rainfall.

Adding ridge vents won’t stop new leaks from forming along the existing seams in your roofing material.

Keep reading below for additional options that can help protect your rooftop.

What Happens If The Attic Is Not Vented?

If you cannot ventilate an attic properly, it can lead to a buildup of moisture and mold, which will make your items smell terrible.

In addition, without adequate ventilation, there is also a higher risk of developing dangerous breathing problems such as asthma. 

It’s easy to avoid these issues by maintaining proper ventilation through vents or fans that expel hot air from attics.

Do I Need An Attic Fan If I Have A Ridge Vent?

No. You do not need a roof vent, either an attic fan or a roof ridge vent.

The purpose of an attic fan is to exhaust hot air from your living space through the attic and out the rooftop.

It’s designed as a connection between your house interior and the outdoors. In the summer, it can be very helpful with cooling down your home .

You are creating a vacuum where cool outside air comes rushing in to replace the hot air exhausted from underneath.

For those people who choose not to use an attic fan, they will most likely have a ridge vent that operates on the same premise as an attic fan

–allowing for continuous airflow into and out of their attic–but instead of using electricity to create an effect, they rely on natural air convection to move air in and out.

Most people will use both an attic fan and ridge vent together; however, using them alone is still more than enough for proper ventilation and cooling off your roof and attic space.

Do You Need To Vent A Finished Attic?

Yes. This is because it will cause the attic to have less heat than unvented, which can lead to ice dams forming, which can cause whole house damage.

Venting a finished attic serves two purposes:

1) To provide adequate airflow for convection to dissipate the heat.

2) To provide insulation that the building code requires.

Unvented attics must have a minimum of R-38 insulation.

In contrast, vented attics require a minimum of R-49 because the moisture from within the home will condense on the roof sheathing when it gets cold, causing rot.

The National Roofing Contractors Association states that while ice dams occur in unvented roofs during extreme conditions.

They are more common in vented roofs because of inadequate ventilation .

There’s enough ice buildup on homes without proper air circulation.

Some areas have had to implement a building code requiring 1 square foot of net free ventilation area for every 150 square feet of attic floor [2].

The other consequence of not venting a finished attic is that it will have reduced air quality. In an unvented attic.

The “stack effect” forces warm air into the upper levels of the house through cracks in the ceiling and around windows during wintertime, which means less fresh air gets inside.

It also means pollutants from these areas get recirculated throughout your home instead of exhausted outside.

Do You Need Gable Vents If You Have A Ridge Vent?

Yes, you do. Gable vents are a necessity in any home, including homes with ridge vents. There are several reasons.

1) Ridge vents work by allowing hot air to escape through the roof of your home and causing cool air to be fully drawn in from underneath your shingles more easily.

Replacing that hot air within your attic space without letting too much heat out into the environment.

This ventilation style is usually called wind-washing or wind-scooping, and it works very well when done right.

However, some problems can arise when a ridge vent is not installed as expected.

For example, if your attic is not properly insulated — or if there is an insufficient amount of insulation — then the areas around the tops of your walls will not be properly insulated.

That means that the cool air drawn into your attic through the soffits will no longer have anything to counteract the hot air within your attic.

It will simply blow right out of the ridge vent to escape. Therefore, when you are looking for an efficient way of ventilating your home.

You need gable vents, too; they ensure that there is a complete flow of airflow throughout your entire roof cavity.

2) If you plan on using fans with your ridge vents, then gable vents are necessary for them to work properly.

A fan placed next to a sheer drop like a ridge vent can create negative pressure.

This means it can cause more warm air to be directly drawn into your home from the surrounding environment.

For this reason, it is much better to use a low-profile gable vent that you can place directly in front of your fan.

This is so that when the fan draws air out of your attic, it will push through the vents rather than pull air back in around them.

This way, you get the benefits of both ridge vents and fans without having to worry about any negative effects on your roof or in your home.

Are Ridge Vents Better Than Attic Fans?

No! Ridge vents and attic fans have pros and cons that make them perform differently in certain situations and climates.

The first thing to note about ridge vents is that they do not provide any form of cooling or heating while an attic fan does.

This makes it difficult to use a ridge vent when you need air conditioning because there’s no ventilation taking away the hot air from home during summer months.

While an attic fan will help cool down your house by drawing in cooler outside air through open windows and then pushing out hot air from the attic.

The downside to this method is that you open windows and lose conditioned air.

Whereas an attic fan forces hot air out while keeping your windows closed and drawing in cooler outside air without losing conditioned warm air into the attic.

The other difference between ridge vents and attic fans is their installation.

Ridge vents are usually installed on top of a house’s roofline, while attic fans are usually mounted inside a home’s soffit or roof area/

They can also be wall-mounted or ceiling-mounted depending on what you prefer.

Some people like having the freedom to move around to clean under their soffits, while others enjoy doing it with no ladder for easy access.

If you have a natural gas-powered ducted heating, then you can have your soffit vents connected to the same venting system as your furnace.

This will help circulate air into your home more efficiently by drawing air from both sides of the house.

Attic fans are usually less expensive than ridge vents. Still, you’ll need to do some research on brands before purchasing one.

This depends on whether it’s solar-powered, battery-operated, wall-mounted, ceiling-mounted, and requires a timer for use.

Can You Spray Foam In A Vented Attic?

Yes, but there are some restrictions. In most cases, you can’t have insulation between the rafters.

They must be at least 24 inches apart so that the foam can get in all the nooks and crannies.

The best time to apply this type of insulation is when your house is being built or doing major repairs on your home.

The most important part of insulating a home is making sure that there are no gaps in the insulation.

To do this, you want to make sure that either blown-in or batt insulation has well-insulated all your attic spaces.

When choosing between foam and cellulose, they both can serve a different purpose for blocking heat transfer through a vented space.

Cellulose is usually used in areas where major heat loss occurs, such as larger cavities with many small studs.

Or where there might be an abundance of moisture from cooking, bathtubs, and showers.

Foam will add thermal resistance properties to overall assemblies, especially if holes exist for cold air drafts.

Also, the foam provides a critical secondary moisture barrier that is very important when applying insulating material above your roof deck.

Wherever you decide to apply either type of insulation, it is always best to have a vapor retarder installed prior.

When installing any insulation, it’s best to use 6-mil black plastic or vented batting to prevent settling against or between rafters and joists.

This provides an effective thermal break for both types of insulation in the assembly.

Does Spray Foam Insulation Cause Mold?

Spray foam insulation rarely causes mold to grow because of its lack of moisture buildup.

However, if there is already a preexisting issue with excessive moisture in the home, adding spray foam insulation may worsen.

It’s important to keep the humidity levels at an appropriate level before installing any insulation in your home, so you don’t create more problems than you solve.

To prevent potential issues from arising, I recommend contacting a professional who specializes in air quality and helps homeowners avoid these unfortunate scenarios.

They does this by providing them with personalized solutions that work best.


Ridge vents, also known as soffit vents, help circulate air throughout your attic and can be a large factor in the heating and cooling of your home.

If you’re looking for an effective way to keep cool, then adding ridge venting is one option that will work wonders.

As with any project, there are some things homeowners should know about before installing them in their house.

For example, if you have a finished attic, it may not need ventilation because most insulation does not produce moisture or heat, which would cause mold growth.

When deciding whether to add gable vents, consider how much time the outside temperature changes between day/night temperatures.

This could affect airflow throughout your roofline.
