Attic fans are a form of roofing ventilation that help to move warm air out of your attic, and are much more effective at moving air out of your attic when compared to passive attic vents. This improved ventilation within your attic confers a number of benefits to your home. Understanding what the benefits of attic fans are can help you decide whether or not you should get attic fans installed within your roofing system.
Increased Comfort Levels
Attics can become extremely hot in the summer months, because of two reasons. Firstly, heat rises, which means that all the heat within your home will begin to collect in the attic. Secondly, the sun will warm up the roof and increase the temperature of your attic even further. Attic fans provide an effective way to cool down your attic by moving this heat out of your home at an extremely fast rate. This lower attic temperature will also translate into lower temperatures throughout the rest of your home, and create breezes and ventilation that will keep comfort levels high even during very hot days.
Lower Energy Bills
In the same vein as the above point, decreased temperatures and increased ventilation within your home will keep your home cooler. This will reduce the overall amount of stress placed on your central air conditioning system. As attic fans are much smaller appliances than air conditioners, they use much less energy, which means that running your attic fan more often and reducing your air conditioner use can save you money on your energy bills in the long run. Furthermore, some attic fans are solar powered, which means that they will offer even greater savings by not using your home's electrical system at all.
Extended Roof Life
Heat within your attic can increase the amount of wear that is placed on your roof. This is primarily because of hot, humid air, which provides the ideal environment for mold and mildew to begin growing. Mold growth within your attic can quickly spread to your roof's support system, insulation, and even to the roofing material itself, which can cause structural degradation that allows the elements to enter your home. This can result in expensive roof repairs or replacement. An attic fan will move hot and humid air out of your attic, increasing ventilation and making it much harder for mold to begin to grow in your attic or your roof, reducing the amount of roofing maintenance that you will have to do over time and saving you money.
