Even though your attic is commonly thought of as a place to store old, no longer used items, in actual fact, when it is properly maintained, it plays an important role in managing the air flow in your home. When air flow is constantly managed, it reduces heating and cooling-related energy expenses, and at the same time prevents mold growth. A well-ventilated attic will also help to extend the life of your roof’s shingles and improve home comfort.
One of the most efficient ways to improve attic ventilation is to install a solar attic fan on your roof. It’s simple to install and does not require construction permits, or complicated electrical work, and needs minimal maintenance once it’s up and running.
How does a solar attic fan work?
Instead of using electricity a solar attic fan uses the sun’s energy to power its motor. It only takes 15 minutes to install a solar attic fan, and once installed the sun powers the fan. A solar attic fan provides up to 400 CFM of venting power per 1000 square feet of attic space expelling heated air from the attic and replacing it with cooler air from outside.
In the summer, your attic can reach temperatures of 160 degrees Fahrenheit or higher without adequate ventilation. This heat buildup is trapped in the insulation and ductwork, potentially causing damage to the roofing materials and increasing the strain on your air conditioner. A solar attic fan circulates attic air continually to prevent heat and moisture buildup.
Warm air from the living space below rises into the attic space during the winter months, where it meets with the chilly underside of your roof. As the hot air cools, it condenses, causing rot, mildew, and mold to form, damaging your roofing materials and insulation, and also your exterior appearance. A solar attic fan sends cool, dry air into the attic space in the winter, at the same time maintaining the outside and attic temperatures as close as possible. Moisture does not build up as a result of this constant exchange.
