If you want to avoid roof repairs and keep your roof in great shape, your attic must be properly ventilated.
In a previous blog, we talked about ice dams and the damage they can cause to your roof. Ice dams are formed when an attic isn’t properly ventilated and the heat from inside the attic seeps through the roof and melts the snow. Once the snow reaches the edge of the roof, it refreezes, forming a dam. Ice dams can lead to roof leaks and a whole host of other unpleasant issues, and the only way to prevent ice dams for good is to ensure that your attic is ventilated as it should be. Proper ventilation also helps to improve your home’s efficiency and control the moisture in your attic, but how do you know if your attic is properly ventilated or not?

Signs of an attic that isn’t ventilated properly:
- Clogged soffit vents – The vents that allow warm air and condensation to escape from your attic can be found in the soffits of your home. Over time, these vents can become clogged or blocked by debris, such as twigs and leaves. Some animals, typically birds, also tend to make their homes in these vents, making it impossible for air to leave as it should. Simply having attic ventilation isn’t enough if you don’t stay on top of it to ensure that the vents are clear.
- Heat radiating from your attic – Can you feel the heat coming from your attic even before you open the door? If the air has nowhere to go, it will stay trapped in the attic. As we mentioned above, in the winter, this can lead to ice dams, and in the summer, this can greatly hinder your HVAC system’s energy efficiency because all of that extra heat will force your air conditioner to work harder than it normally would have to.
- Mold – Not only does ventilation help the warm air escape safely into the outside world, it also reduces the condensation that can build up in your attic. Without the proper insulation, that moisture can’t go anywhere, and it can seep into the insulation in your attic, as well as the roof sheathing and decking. If these areas remain moist for long enough, mold can start to develop.
- Visible rot – An attic that isn’t properly ventilated is prone to large shifts in temperature. These shifts can wreak havoc on the wood inside the attic, causing it to shrink and expand, which causes cracking. This kind of damage can also be found on your roof.
