Residential Attic Ventilation
It’s Texas; the hot air in your attic must be eliminated daily!
You have a choice with your new roof installation. Either stay PASSIVE or get PROACTIVE.
It’s no secret that during any given Texas day, attic temperatures can reach well above 150 degrees. We all know that “hot air rises.” Unfortunately, it also expands and radiates which creates “heat gain” in your attic and the layers of insulation you have installed. There is no question the ridge vents and box vents do exhaust hot air, however, by the time the heat stacks up and starts expanding to move up and out, your attic’s insulation is already baked. In short, the convection-ventilation process actually requires a certain amount of heat retention to build up before it begins the ventilation process!
Once heat gain starts in your attic, the battle is already lost!
Your home’s attic insulation is going to bake all day.
PASSIVE ventilation (convection-ventilation) methods are what most roofers and builders use. The hot air in your attic heats up, rises, and stacks, trying to make its way up and out.
Convection-Ventilation Roof Fixtures Include: Box Vents, Dome Vents, Ridge Vents
PROACTIVE ventilation methods are more effective and efficient at removing the hot air and preventing heat gain from building in your attic daily.
Attic Temperature Inversion
Every night after dusk, the heat of the day drifts off and gradually the cooler, wetter air of the evening resides in your attic. By the next morning, the process is reversed and the heat oppression continues in this cycle. In addition to the heat gain, this wetter night air is the primary cause for mold and mildew problems in attics.
The Solar Attic Fan is the only proactive solution to both of these problems.
PROACTIVE Roof Fixtures Include:
The key to it all. Cooler morning air comes in through the soffit vents, helping keep your attic insulation from gathering heat gain.
Solar Attic Fans
Turn on with the morning light and start pulling hot air out before the day heats up, while the soffit vents allow cooler air in the attic from the bottom.
Solar Attic Fan Benefits
Solar attic fans are on at dawn, exchanging the night air before the heat of the day ever gets going. They come with a 25 Year Rated solar cell which keeps them running very quietly for years to come. The system helps lower temperatures by exchanging the air of the attic through soffit vents located on the eaves of the roof area. With this attic system set up, the exterior ambient air is being exchanged quickly enough that heat stacking and heat gain never get established. This type of Attic Ventilation System can lower energy cost, lower your ceiling temperature, and help protect your home’s vital attic equipment and anything else you may store up there.
Attic heat translates to rising ceiling temperatures.
Roof Turbine Vents
Turn all day and night, proactively helping to pull hot air out of your attic.
Power Attic Fans
Work well, but cost approximately $20/month to operate, per unit. They also need new motors about every 2 years with the constant use they receive here in Texas.
