Free Solar Powered Attic Fan with a Full Roof Replacement
Benefits of a solar powered attic fan:
HELPS REDUCES THE COST OF RUNNING YOUR HVAC
The most obvious reason for attic ventilation is to lower the attic temperature during the warmer months. No matter how much insulation is in the attic, heat can still transfer into adjacent living spaces. In fact, extra insulation can actually add to temperature increases because heat is trapped in the insulation. A solar powered attic fan removes this excess heat build-up, reducing the load on your HVAC.
EXTENDS THE LIFE OF YOUR ROOF
Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is what happens when an attic isn’t properly ventilated. Hot, moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out. Moisture in the attic also causes mold to develop on the interior walls. Cold air in the attic space will not affect the temperature in the adjacent living spaces if properly insulated.
REDUCES MOISTURE BUILD-UP
In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of a moisture problem is rusty roof nails sticking through the roof deck.
GET A TAX CREDIT
The solar attic fan is eligible for a 30% (of the installation cost) tax credit according to the Energy Policy Act of 2005.
