What Happens if Your Attic is Poorly Ventilated?

Proper ventilation in your attic is an important factor for optimal home performance, it can cause several problems including overworking your HVAC system, poor indoor air quality and the dreaded ice dams in the winter months. Also, if your attic is not probably ventilated it can quickly become overheated and become a magnet for mildew and even mold.  Here are potential problems of a poorly ventilated attic:

Heat Buildup

Attics can heat up to 150 degrees Fahrenheit or more in the summer, which can lead to problems with your HVAC system, such as premature wear and tear on the equipment and higher energy bills.

Moisture Buildup

Warm air can hold more moisture than cold air, so when warm air from the house rises into the attic, it can cause condensation and moisture buildup. This can lead to the growth of mold and mildew, which can damage your insulation and roofing materials.

Ice Dams

Ice dams are formed when melted snow on the roof refreezes at the eaves, causing water to back up and leak into your home. They are more likely to form in homes with poorly ventilated attics. The weight of snow and ice can put a lot of stress on your roof, and without proper ventilation, the snow and ice will melt more slowly, which can increase the risk of roof damage.

Poor Indoor Air Quality

The heat and moisture in an unventilated attic can create poor indoor air quality, which can contribute to respiratory problems and other health issues.
