A roof fan is a necessity for your attic since it pulls excess heat and moisture out and away from your home’s roof. It provides the circulating air necessary so mold and mildew don’t get started on the rafters or insulation, keeps energy bills down during the summer by ridding the attic of excess heat and stops ice dams from building up on your roof’s gutters in the winter by keeping the temperature in the attic at a consistent level of heat.
Roof fans may look easy to install on the surface but putting one in means cutting a hole in your roof, ensuring a water tight seal for the fan and getting in the wiring as needed. While asphalt shingled roofs are easy to cut, wooden shingled, metal shingled, clay tiled and slate roofs need the expertise and experience of your local roofing contractor. He can also advice you if it would be better for the integrity of your roof to simply place your new roof fan into an already existing static vent or the replaced fan hole.
Besides using electricity, roof fans can be wind-driven or solar powered. Barns, large industrial buildings, garages and even chicken coops usually have the wind powered ones since the interior heat is provided by the activity within the structure and simply needs to be siphoned off through a simple wind turbine. A newer style of roof fan, designed to appeal to the ecologically minded or for those homes where electric wiring is difficult to access, relies on small solar panels for its source of energy.
