It's interesting to note that nine out of ten homes in the United States don't use proper attic ventilation methods. While this seems like a minor detail, it can actually add up to many problems for homeowners if it's not corrected. By having proper attic ventilation methods in your home you can save your roof from warping, reduce your energy costs, and reduce the amount of moisture in your home. All of this adds up to fewer headaches for you as a homeowner.
When the heat in your attic builds up from a lack of proper attic ventilation methods, your home will become warmer. As this happens, it can create a hot exterior surface on your home, leading to a very hot roofing area. When the shingles or tiles on your roof get that hot, they can begin to breakdown and warp. This can cause you to have a higher chance of leaks from your roof as well as need to replace the roof more often than you might have with proper ventilation. Since heat rises, one of the first places to show the effects of poor ventilation is the roof.
Proper Attic Ventilation Methods
In addition, proper attic ventilation methods can help you reduce your energy costs. Because your home is much warmer as a result of poor ventilation, you will need to run the air conditioner more in the summer. While this doesn't seem like a tremendous problem, the super hot air from the attic will seep down into the home, potentially causing the wallpaper and the paints on the walls to also be affected by the change in temperature.
And finally, without proper attic ventilation methods, you can see a buildup of moisture in your home in the winter. Because the hot air is being trapped in the attic and the cooler air from the outside is interacting with that higher temperature, you can begin to see wetness on your appliances as well as your ceilings. This moisture can lead to problems with mildew and mold in your home.
