Cooling Down the Attic

Posted on February 4th, 2016 by Jupiter Tequesta

Did you know that an inadequately ventilated attic can reach a whopping 150 degrees on particularly hot days? That’s 50 degrees warmer than it should be.

When an attic overheats, it can affect everything from your roof to your air conditioning system. An extremely hot attic can cause roof shingles to essentially bake, leading to deterioration. It also makes your air conditioner work harder to keep your home cool, causing energy costs to skyrocket.

Fortunately, there are simple steps you can take to cool down the attic:


1. Add ventilation

Electric ventilators and attic fans can significantly reduce attic temperatures. They rely on thermostats that turn the fan on once the attic reaches a certain temperature. We recommend setting the thermostat to 100-110 degrees. You can also add passive vents (i.e., gable, soffit and ridge vents). These are designed to let hot air escape through openings in the roof.

2. Do the math

However, don’t blindly install vents. It’s important that you have one square foot of venting space for about every 300 square feet of floor space in your attic. Follow these guidelines for best results.

3. Install insulation

Finally, make sure your attic is properly insulated. It’s recommended that your insulation has an R-factor (thermal resistance) of at least 19. High quality insulation will go far in preventing hot attic air from entering your home’s living area.
