Why You Need a Well-Ventilated Attic

How often do you go into your attic, especially during the summer, and immediately think, “It’s hotter than Hades in here?” If you’re like most people, it’s pretty much every time. That ’s because your attic has little to no ventilation.

While you may think of home ventilation only in regards to your bathroom or kitchen, it’s very important to have a well-ventilated attic too! Here’s why:

Heat and Moisture

One of the biggest issues poor attic ventilation can cause is extreme heat and moisture build up. Besides causing you to feel all but suffocated when you try to go into your attic, all that heat and moisture can affect specific areas of your attic, such as trusses and rafters, and cause them to become warped.

If that happens, your roof can become damaged to the point that it collapses. Not good!

Damage to Insulation

Your attic insulation is responsible for keeping your home toasty in the winter and cool in the summer — but a lack of proper ventilation can ruin your insulation. If all that heat and moisture has no way to exit your attic, it can get absorbed into your insulation and ruin its integrity.


If there is any moisture buildup anywhere in your home, you’re at risk for mold growth. While common spots for mold include your basement and bathroom, your attic is also particularly susceptible to mold. What’s worse is that, since you’re not in your attic all that much, you probably wouldn’t notice the mold until it was too late and you needed major repairs.
