Portland Attic Fan Installation & Roof Ventilation Services

Proper roof ventilation is one of the best ways to ensure your roof lasts as long as possible. Proper ventilation helps:

• Prevent mold, rot, and ice buildup. Roofs that are properly vented have a constant stream of airflow, which allows moisture to escape the roof. This helps prevent mold and mildew from growing, the roof structure from rotting, and ice from building up on eaves in winter.
• Reduce inconsistent temperatures. Proper roof ventilation helps ensure temperatures in your home are more consistent. Expelling the hot air from your roof prevents it from sitting in the attic, which can significantly increase the temperature of your home’s upper levels.
• Improve energy efficiency. By ensuring temperatures in your home stay consistent, your HVAC system won’t work overtime. This helps keep your electricity bills down and allows your HVAC system to run as efficiently as possible.
• Increase roof longevity. Heat and moisture can quickly be the downfall of any roof. Moisture buildup can deteriorate the roof structure and insulation, requiring a new roof sooner than you’ll need it. Proper ventilation ensures your roof stays as dry as possible, helping it last that much longer.

Does My Home Need An Attic Fan?

Attic fans can be essential for maintaining a comfortable and energy-efficient home. They can regulate temperatures and reduce moisture, potentially lowering cooling costs and prolonging roof life. Common types of attic fans include:

• Traditional electric attic fans – Typically installed at the roof’s peak or gable end. They can effectively remove hot air and moisture from the attic but require a constant power source and may increase electricity bills.
• Solar attic fans – Solar panel-operated to achieve energy efficiency and lower electricity costs. We use QuietCool solar attic fans for superior performance and reliability. Still, their efficiency is dependent on sunlight availability.

Nevertheless, not every home needs an attic fan. Roofs with natural airflow, like those with ample soffit and ridge vents, might not benefit from an attic fan. However, homes with low-sloped or flat roofs may demand additional air circulation.

Humidity and heat are the two most significant issues for attics. Humidity can lead to mold and mildew in the attic, while heat can shorten shingle life, void the manufacturer’s warranty, and increase energy or cooling costs. To combat this, having a sufficiently sized and powerful attic fan is crucial to expel stale air and provide significant benefits.

Attic fan installation in Portland, Oregon, usually includes evaluating your roof design and condition, choosing between a solar or traditional attic fan, mapping out ideal fan locations, and modifying the attic’s framework before installing the fan with proper insulation, sealing, and an attic fan thermostat. Solar-powered attic fans may be easier to install, thanks to their standalone power source, while traditional fans may require more complex electrical work.
