Cool Down Your Attic and Beat the Heat: Tips to Make It Happen


Certain types of insulation, such as reflective insulation, can be incredibly effective at keeping heat out of your attic and home. Their reflective properties send heat right back outside, helping to keep your attic cool and comfortable.

Attic Ventilation

One of the easiest and most cost-effective methods for cooling down an attic is installing more vents and exhausts. This allows for natural ventilation, allowing hot air that accumulates in your attic to circulate in and out.


A simple and discrete addition, fans can make all the difference when it comes to cooling off an attic. You may want to consider adding a few to evenly distribute the cool air.

Air Conditioning

If your attic is in need of more than a gentle breeze, then you may want to consider adding an air conditioning system. It’s more expensive than other cooling methods, but it will get the job done efficiently.

  Cool Down Your Attic and Beat the Heat: Tips to Make It Happen

Cooling down an attic can be a challenging task due to the intensity of the heat and the high-density of the material used in the attic space. As an experienced homeowner, I have found that employing various tactics, such as insulation, attic ventilation and fans, as well as installing air conditioning in the attic, to be effective in cooling down an attic.

The right type of insulation is essential to ensure that heat doesn’t slowly seep in and make the attic too unbearable. Reflective insulation is a good choice as it prevents the heat from getting in while also reflecting the heat away from the attic to keep it cool.

In addition, attic ventilation is helpful to allow hot air to circulate in and out of the attic in a natural manner. Installing fans in the attic can help to move the hot air out of the attic and replace it with cooler air. Lastly, if needed, air conditioning can be installed to provide a reliable and more powerful system to keep the attic cool.

Overall, by using the right combination of insulation, attic ventilation, fans and air conditioning, you should be able to keep your attic cool and comfortable, often without major disruption to the daily life of your family.

Frequently Asked Questions

How can I cool down my attic fast?

You can cool down your attic fast by installing electric ventilators and attic fans, which are designed to remove hot air from the attic. They have thermostats that turn the fan on when the temperature reaches 100-110 degrees. Alternatively, you can install passive vents such as gable, soffit and ridge vents which are openings in the roof that allow hot air to escape.

How do I stop my attic from getting hot?

To reduce the heat in your attic, you can cover up windows with shades or blinds, install ridge and soffit vents, install fans, insulate your attic, and consider AC units. Follow these five steps in order to stop your attic from getting hot and to help regulate the temperature inside. These steps can not only keep your attic cooler, but they can help with energy efficiency throughout your home as well.

What temperature is too hot for an attic?

Attics should not be hotter than 130 degrees Fahrenheit. This temperature can cause issues with energy bills, as well as damage the roof. If it is summer, then it is best to keep the attic temperature no more than 10-20 degrees above the outdoor temperature.

What happens if attic gets too hot?

If an attic gets too hot, it can lead to several problems. High temperatures can shorten the life span of shingles, deteriorate items stored in the attic, and cause moisture issues in the house. In summary, having a hot attic can cause serious damage, and should be avoided whenever possible.

How hot should attic be on 80 degree day?

On an 80 degree day, the ideal attic temperature should be between 80-100 degrees Fahrenheit. An attic temperature climbing above 130 degrees can lead to an increased energy bill and damage to your roof. To ensure an optimal attic temperature throughout the year, it is important to monitor your attic and make any necessary adjustments.

How hot can an attic get on a 90 degree day?

An attic on a 90 degree day can get very hot. More often than not, attic temperatures will exceed 125 degrees on a 90 degree day. This excessive heat can overwork air conditioning equipment, run up utility bills and shorten the life of a roof.

How hot is an attic if its 100 outside?

An attic can easily reach 170 degrees or more if its 100 degrees outside. Extreme temperatures in attics can cause damage to the home and can also be dangerous for anyone inside. Proper ventilation is important in order to ensure the space remains cool and safe.

How many degrees hotter is the attic?

An attic that is not ventilated can get up to 150°F, 50°F hotter than what it should be. That temperature increase is a significant amount and can cause damage to the asphalt shingles on the roof. In conclusion, an unventilated attic can be 50°F hotter than it should be.

Does a hot attic heat up your house?

Yes, a hot attic can heat up your house. The sun’s rays blast the roof surface and transfer heat into the living spaces of the house. Insulation, a radiant barrier, or an attic fan providing ventilation can stop the heat from entering the house.

Does attic temperature affect house temperature?

Yes, attic temperature does affect house temperature. As the attic heats up in the summer, the heat can seep into your home, affecting the internal house temperature. A hot attic can cause the cool air from your air conditioning unit to be lost quickly, making it hard to keep your house at a comfortable temperature. Installing insulation and a vent to help regulate attic temperature can help to keep your home cool.

What happens if your attic is too hot?

If your attic is too hot, it can damage your roof’s asphalt shingles, leading to costly repairs over time. It can also cause your air conditioner to work harder than it needs to, resulting in higher energy bills. Finally, the increased heat will make your home less comfortable during the summer months.

Does cooling your attic help cool your house?

Yes, cooling your attic can help cool your house. By cooling your attic, the temperature in the room below it will be more comfortable during the summer months. Cooling an attic also helps protect your home’s structure from sustained damages, and can increase your energy efficiency in the long run.

How do I cool my attic bedroom?

An attic bedroom can be cooled by providing adequate ventilation. Installing an attic fan can be effective by drawing in fresh air from the outside and expelling hot air from the attic. The fan should be installed near a roof vent, window, or gable wall to allow for better air circulation.

How does insulation work to cool an attic?

Insulation works to cool an attic by preventing heat from radiating downward and by stopping cool air from escaping back up into the attic. It does this by creating an air barrier between the attic and the house, trapping warm air and preventing the temperature in the attic from rising. This helps maintain a comfortable temperature in both the attic and the rest of the house.

Can an attic fan improve attic air circulation?

Yes, an attic fan can improve attic air circulation. Attic fans draw cool air into the attic and expel hot air faster than static air vents, allowing air to circulate throughout the room and reduce overheating. To learn more about attic fans and how they can help, click here.

Should you lower the temperature of your attic?

Yes, you should lower the temperature of your attic. Doing so is beneficial whether there are ducts in the attic or not. Lowering attic temperature reduces air conditioning costs, and it can also help protect stored items from heat damage.
