Many people mistakenly think that attic ventilation is only necessary in warm climates – thinking that here in Chicago; we do not need to worry about it. In fact, the exact opposite is true; we need attic ventilation year round in order to protect the attic and the roof.
Extend the Life of your Roof
Perhaps the most convincing reason that attic ventilation is important is to increase the life expectancy of your roof. In the winter, your roof needs to be protected from the frigid temperatures. If the attic is not ventilated, certain areas of the roof will get too warm from the furnace running all of the time. A warm roof means that the snow or ice that is there will prematurely melt. As it travels down towards the soffits, it could refreeze because of the drastic temperature difference in that area. This eventually causes an ice dam, excessive weight and severe damage to your roof, oftentimes requiring a roof replacement.
Extend the Life of your AC Unit
In the summer, attic ventilation helps your AC unit last longer. It does so by allowing the hot air that is trapped in the attic out. This will decrease the temperature of the air in your home, therefore, decreasing the amount of time that the air conditioning unit has to run. This has many benefits, aside from the fact that you will save wear and tear on your AC unit, you will also lower your utility bills, conserve energy and be more environmentally friendly.
Avoid Mold Problems
When ventilation is not plentiful, moisture can accumulate. The dark, damp areas of the attic are the perfect place for mold to start growing. If you have ever climbed into your attic and wondered what that musty smell was – chances are it was from excessive moisture and/or mold. Mold can cause serious issues for your home as well as your health, making it imperative to ensure that your attic has proper ventilation.
Aside from mold growth, moisture in the attic can eventually cause issues for the structure of your attic and/or roof. Leaking water can rust nails and the wood of the roof deck can begin to deteriorate. The more moisture that is present in the attic and near the roof, the weaker the roof becomes.
If you are unsure about the ventilation in your attic, it is well worth the time to have it inspected to ensure the overall health of your home and your family. Proper ventilation can make a difference in how your house runs, how everyone in your family feels and even how high your utility bills may be.
