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. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by up to 40°F. 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. Proper ventilation removes this 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.

Reduces the Load on Your HVAC System

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. In fact, asphalt shingle manufacturers warranties require proper attic ventilation. During the colder months, attic ventilation removes the warm, moist air that heat sources produce. 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.

Attic Venting Key Concepts

Attic ventilation is an important aspect of maintaining the structure of your home as well as saving energy. Improper attic venting can lead to moisture buildup that can cause mold growth and also cause wood rot. The key to proper attic ventilation is to create continuous air circulation throughout the attic space while preventing moisture from entering. In an ideal venting system, air should enter the attic from the eaves or soffits and escape outside at the roofs ridge.

Solar Attic Fans Work With Your Existing Passive Vents

If you've ever been in your attic, you know just hot the space can get, especially in summer months. The sun beats down on the roof surface and heats up the stagnant air inside the attic. Building codes require homes to have a passive vent system. But, passive ventilation does not provide the pressure needed to force the air through the attic and outside. That's where a motorized fan comes in. An attic fan placed at the roofs ridge will pull air in from outside, force it to move through the entire attic space and escape through the attic vent. In summer months, a solar attic fan can reduce the temperature in an attic by up to 40°F!

Solar Attic Fans Operate Using Free Solar Energy

A solar attic fan is a simple way to add a motorized venting system to your home without needing any extra electrical wiring or structural changes. Solar Attic Fans are manufactured using high-impact photovoltaic solar panels to power the fan for free all during the day. The units are fully operational right out of the box and install in less than an hour.  Fans are available in 4 model sizes to accommodate any attic space - 10, 20, 30 or 50 watts. They are also available in 3 mounting types: roof, curb or gable.
