3 Reasons a Well-Ventilated Attic is Important in Ann Arbor Michigan

  1. Heat & Moisture

If you’ve ever briefly stepped foot in your attic during the summer, you know that it gets extremely hot and humid. Unfortunately, some structural components that are located in your attic require heat and moisture regulation in order to remain in mint condition.

If you don’t have proper attic ventilation, elements of your roof, such as the deck and trusses, can potentially experience heat damage if they are exposes to extreme heat for a long period of time. Essentially, this could potentially weaken the structure and cause your roof to collapse.

  1. Mold & Mildew

Heat and moisture go together with mold and mildew like two peas in a pod. In other words, if your attic is experiencing an excess of heat and moisture, you can expect there to be an influx of mold and mildew as well.

Unfortunately, mold and mildew tend to grow faster and with more abundance in attics because no one really spends time up there. This is also potentially detrimental because there will most likely be serious damage by the time you realize you have a mold and mildew problem.

  1. Insulation Damage

By now, you should know that without proper attic ventilation, your attic is at risk for experiencing an influx of heat and moisture. High levels of heat and moisture could potentially seep into the insulation in your attic, which in turn causes damage.

One of the biggest problems this creates is throwing off your home’s energy efficiency. In other words, you might catch yourself blasting the air conditioner or heater because all of a sudden your home’s temperature doesn’t seem as moderate and controlled as it used to.

If you don’t pick up on yourself blasting the air conditioner or heater, you’ll definitely be able to see the difference in future utility bills because they will most likely significantly increase.


As you can tell, attic ventilation in your Ann Arbor Michigan home is extremely important for a variety of reasons.
