The Benefits of Proper Attic Ventilation

Improve Your Home’s Energy Efficiency
The reduced temperature in your attic will also assist your air conditioner by keeping the ductwork and the air inside cooler. The resulting effect will be cooler air flowing through your HVAC system and reduced strain on your a/c unit.

Extend the Life of Your Roof
When your attic heats up, the roofing underlayment under your roof shingles can also heat up and, over time, become brittle and ineffective. By lowering your attic temperature you can extend the life of your roof and save the expense of repairs and replacement.

Keep it Cool in the Summer
During the peak summer months, your attic’s temperature can rise to 160° or more. This heat build-up can then raise the temperature inside your home and increase the amount of electricity used by air conditioners and other cooling equipment.

Installing a Solar Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature.

The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.

Remove Moisture and Reduce Harmful Mold and Mildew

In the winter, warm moist air rises from the inside of your home and collides with the cold underside of the roof. U.S. Sunlight Solar Attic Fans provide the air circulation which prevents the moist air from condensing on the surface, keeping your attic drier and helping to prevent mold and mildew from forming inside your attic and ice damming on your roof.

Moisture in the attic can also lead to other troublesome problems. Humidity can cause saturated insulation, sheetrock pops and truss uplifts, which can cause damage and cracks to the drywall inside your house.

Solar attic fans and solar powered gable vents are both great ways to effectively ventilate your attic while saving money on electricity.

Prevent Ice Damming
If you live in an area that has snow, the warmer attic air will heat the roof and melt the snow which drips to the eaves where it can refreeze as ice and form ice-dams under the eaves. These ice-dams will cause water to work back up under the shingles into the attic and down to the ceiling.
