How Do I Keep My Attic Cool in the Summer?

Did you know an attic that's not vented could reach up to 150 degrees on hot summer days? This is about 50 degrees higher than this area of your home should be at any given time, and it can contribute to a wide range of issues. One of these is the possibility of roof damage. What's more, a hot attic could have your air conditioner working overtime, which could mean higher utility bills and frequent repairs. Fortunately, there are some things you can do to keep your attic cool in the summer.

Use Electric Ventilators and Attic Fans

An electric or power attic ventilator removes hot air from your attic to keep the temperature lower. It's often connected to a fan and mounted to the roof of your home. It can be connected to your home's thermostat; or a separate thermostat that triggers the fan when a preset temperature is reached in the attic on hot, humid summer days.

Have Passive Vents Installed

A passive vent is so-named because it keeps an attic cooler by creating an opening within a spot near the roof. Passive vents typically include ones in gables, soffits, or the ridge of the roof. These vents give hot attic air a pathway to get out of your attic, so temperatures don't excessively rise.

Space Out Your Ventilation Efforts

Whether you go with electric ventilation or a passive option, make sure you remain mindful of your attic's square footage. Ideally, you want to have one square foot of ventilation or venting area for roughly every 300 sq. ft. of attic floor space.

Explore Your Options with Attic Insulation

Another cost-effective way to keep your attic cooler in the summer is by having it insulated. Use insulation with an R-value of at least 19 when doing so. What this does is help keep hot air in your attic from adding extra heat to your living spaces below. Proper insulation also helps keep your attic cooler by reducing air transfer.

As for the type of insulation to use in your attic to reduce air transfer and minimize heat transfer to lower parts of your home, standard options include:

  • Cellulose insulation
  • Loose-fill fiberglass
  • Spray foam
  • Fiberglass batts

With any type of attic insulation, be sure it's installed correctly, which means leaving no gaps for air transfer. With loose fill, give it sufficient time to dry if you have plans to put drywall over it; otherwise, the R-value will be affected. Also, don't block ventilation in your attic. Lastly, seal any attic ductwork to prevent insulation materials from being circulated through your home.
