Most homeowners know the dangers of moisture in their homes. Mold and mildew are dreaded words that everyone wants to avoid. Make sure your attic ventilation isn’t working against your efforts for a mold and mildew-free home! Attic ventilation allows for the free movement of air into and out of your attic or crawlspace. When done properly, ventilation will not have a negative impact on the climate control of your home. It will, in fact, make it much easier for your attic to avoid collecting moisture.

3 Risks of Poor Attic Ventilation

  1. Roof damage. If your attic is left without proper exhaust and intake of air during the hot and humid summer months, the temperature can rise steadily. The heat, when combined with moisture, can lead to deteriorating or warped shingles and other unsightly and expensive roof damage.
  2. Condensation. That mold and mildew we mentioned above? It is likely to happen after an abundance of moisture is left to form and is unable to dry. During the winter months, warm air from your home can find its way into the attic, causing condensation to form against the cold interior of the roof. This condensation may seem harmless, but left without ventilation, it can cause buckling shingles and water damage that may take a long time to detect.
  3. Ice dams. One of the major risks of poor attic ventilation is ice dams, which occur when snow melts from heat rising into the attic, but refreezes as it travels down the side of the roof and into the gutters. This quick thaw and freeze cycle often leads to issues with draining, permanent roof damage, leaks, and can even cause damage to the walls of your home.
