Ways to Cool an Attic

If you have an attic, you are likely looking for ways to cool it without using too much energy so that you can make this area more functional. In that case, continue reading because here are some ways to cool an attic effectively. Some of these are easy, and some can be more time-consuming.

Installing an Attic Fan

Another way to make the airflow better in your attic is to add an attic fan. What attic fans do is push warm air out and pull cool air coming from the vents found on your roof. However, you have to make sure that your attic has no holes or openings in the area in contact with the ceiling on the top floor.

This is to make sure that the fan properly works. Moreover, you need to ensure that the access door is well-fitted to ensure that hot air does not escape. If not, the fan can move the cool air from the attic upward, resulting in the air conditioner operating for a more extended period. As a result, more energy is consumed.

In addition, using a solar attic fan is an excellent option to circulate cool air in your attic. In fact, using solar products offers many benefits. That is why it is no surprise that 1.6% of the total electricity utilized in the US is solar energy.

Installing an Air Conditioner

Suppose your attic is located in a practical area such as your home office or bedroom. In that case, it’s recommended to install an indoor air conditioner. An air conditioner can help maintain the desired temperature in your attic and make it more comfortable to stay there for a long time.

In fact, the easiest way to cool your attic is by getting a portable air conditioner. This is a standalone device that is only 2 feet tall and 18 inches wide. It’s also easy to move around because it has wheels.

Sealing the Gaps and Cracks

Whether you opt to install an air conditioner or not to cool your attic, you have to make sure that gaps, cracks, and holes are sealed. When these are left open, it will allow warm air to enter your attic, making it hotter, especially in summer.

Moreover, water is more likely to enter your attic if there are gaps and cracks left open. This can result in damaging and rotting the items kept in your attic.

With that said, if the opening is less than one-quarter of an inch, you can use waterproof caulk to cover this opening. Moreover, you use a heat-resistant caulk if the opening of your attic is near the chimney.

On the other hand, using an expandable foam spray is recommended if the opening is bigger than one-quarter of an inch. This can ensure that the gap is plugged in more efficiently, so you do not have to worry about warm air or water getting in your attic.

Adding Ventilation for Better Circulation

Adding good ventilation is another ideal way to cool your attic since hot air is released, which is crucial in summer. Moreover, your roof can get damaged if hot air circulates in your attic. That is because the tiles can overheat without proper ventilation.

In addition, the hot air can also increase moisture so that it can cause mold growth and wood rot. Of course, there are many ways to increase ventilation, but you need to know what type of vent works best for the roof type you have, the airflow you need, and the area where you live.

Therefore, it is best to work with a professional roofer to know how to ventilate and keep your attic cool properly.

Installing a Programmable Thermostat

A programmable thermostat will allow you to set your desired temperature at different times throughout the day. So, if you have an air conditioner in your attic, you can use it when you are home.

In fact, you can get affordable thermostats with four cycles that you can override manually and repeat every day. For the pricier thermostats, you can set it for each weekday and each weekend. Moreover, you can install these yourself because they all come with instructions.


Finally, you know some of the ways to cool your attic. Overall, all these ideas are great for any home. After all, cooling down an attic is not complicated since there are many solutions for it. Now that you have all set up, you can sit back in your recliner and have peace of mind that your attic is cool.

Still, if you are not into DIY, you can always ask or hire an expert to get the cool temperature you want for your attic. They can also advise you on how to save more from your electricity bill when cooling your attic.
