Solar Attic Fans
Why They Just Make "Cents"
Attic venting is an important aspect of maintaining a healthy, energy efficient home. An attic fan works with your existing passive vents to improve air circulation and provide many benefits including:
extending the life of your roof by providing additional ventilation for your roofing system,
increasing the efficiency of your home cooling system thereby saving you money,
making your home more comfortable, and
giving you a one-time energy efficiency home improvement tax credit (good through December 2019).
But here's the best part: There is no electrician or electrical permit required to install it! Say what?! That's right! And in most cases, it takes less than a day to install. Cha-ching! More money saved.
We are certified dealers for Natural Light brand solar attic fans because of their consistent high quality and customer ratings. Plus, they manufacture their solar attic fans right here in the USA.
Pricing is more affordable than you might think. The following is what you can expect to pay for installation on a standard asphalt shingle roof*:
24-Watt Ultra Low Profile**
*Price is for one unit installed and will differ for roofs that are not asphalt shingled. Other restrictions may apply.
**All Natural Light solar attic fans are available in the colors black, gray, and bronze. The 24-Watt Ultra Low Profile is only available in the color black.
How Many Solar Attic Fans Do I Need?
Several factors can affect the amount of attic ventilation a home needs. Variables such as vaulted ceilings, amount of existing venting (soffit, ridge, gable), attic shape, pitch, and obstructions must all be taken into account when calculating the amount of attic venting needed. Roofer Dude® can determine the correct size unit or units are needed for your home.
Benefits of Attic Venting Explained
The Natural Light solar attic fan works with your existing passive vents to improve air circulation. Adding a solar attic fan is a simple and affordable home improvement product that, over time, will pay for itself. Cooling your attic space in the summer can reduce your cooling costs. It will also extend the life of your roof shingles and prevent damaging rot and ice damming in the winter.
Attic Venting Extends the Life of Your Roof
The most obvious reason for attic ventilation is to lower the attic temperature during the warmer months. In fact, asphalt shingle manufacturers warranties require proper attic ventilation. 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 just what happens in an under-ventilated attic. Attic temperatures can exceed 160°F during hot summer days. When you combine the sun exposure from above with the heat exposure from below, the roofing is essentially being baked from both sides reducing its life expectancy. Proper attic ventilation can reduce those temperatures by up to 40°F thereby extending the life of your roof. Although building codes require basic ventilation which is based on natural air movement, typically it's not enough to properly remove the heat build-up in the attic.
Reduces the Load on Your HVAC System
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 making your cooling system work harder. Proper ventilation removes the excess heat build-up. As the heat is exhausted, the workload of your air conditioning system is reduced, thereby saving energy costs and even extending the life of your air conditioning system.
If your air handler and duct work are in the attic and there is insufficient ventilation, it can actually cause your cooling system to initially blow warm air instead of cool air, force your air handler to work harder to cool the air down, and reduce its life expectancy. Again, as the heat is exhausted, the workload on the air handler is reduced thereby saving energy costs and extending the life of the air handler as well as the rest of the air conditioning system.
What maintenance is needed?
Natural Light solar attic fans require no maintenance! The unit has been engineered to be leak proof when installed properly. It also has a protective animal screen that keeps out the critters.
Does the Solar Attic Fan shut off during the winter months?
When Roofer Dude® installs each solar attic fan, we include a thermostat that allows the fan to automatically turn on when the attic temperature reaches about 80 degrees and automatically turn off when the attic temperature lowers to about 70 degrees. Running the fan only when the attic is hotter than 80 degrees extends the life of the fan motor and keeps heat balance in the attic in winter without drawing colder air inside the attic making home heating more efficient.
