Solar Attic Cooling & Ventilation

Save on your AC costs by reducing attic temperatures by 40 degrees, and your home temperature by 10 degrees.

Lower Attic Temperatures and Reduce the Load on Your HVAC System

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

No matter how much insulation you have in your attic, heat can transfer into adjacent living spaces. Extra insulation can actually trap heat and increase temperatures. Proper ventilation will release this excess heat, reduce your air conditioning system’s workload, extend its lifespan, and save energy.

Extend the Life of Your Roofing Materials

During the hot summer months, an unventilated or under ventilated attic can subject roofing materials to higher temperatures that shorten your roof’s lifespan. During cooler months, moisture can enter the attic through air leaks around ceiling light fixtures and bathroom exhaust fans, allowing mold and mildew to grow.

Proper ventilation can extend the lifespan of your roofing materials by preventing heat and moisture issues in your attic.

Asphalt Shingle Manufacturers Warranties Require Proper Attic Ventilation

Attic ventilation is required in cold environments. It allows the warm, moist air that heat sources produce to leave your home. Without proper ventilation, this air can condense on the underside of the roof sheathing, causing mold to develop on the interior walls.

If properly insulated, cold air in the attic will not affect the temperature in adjacent living spaces.
