Solar Roof Ventilators: A Sustainable Solution for Attic Ventilation

Attics are notorious for becoming scorching hot in the summer and cold in the winter. This temperature fluctuation can be uncomfortable for homeowners and can also lead to a number of problems, including:

Extreme heat temperatures can cause asphalt shingles to crack and buckle and wood roof sheathing to wrap.Mould and mildew growth. Moisture trapped in a hot attic can lead to the growth of mould and mildew, which can cause respiratory problems and other health issues.

  • Traditionally, attic ventilation has been achieved by installing roof vents and soffit vents, which allow air to circulate through the attic space. However, these vents are often ineffective, especially in the summer when the hottest air is trapped near the roof.

How Solar Roof Ventilators Work

Solar roof air vents Brisbane are small, low-profile fans mounted on your roof. They are outfitted with a solar panel that converts sunlight into electricity to power the fan. A thermostat is typically included to regulate the fan’s operation, ensuring it runs only when needed.

When sunlight hits the solar panel, the fan turns on and draws hot, humid air out of the attic. This helps to cool the attic and reduce the strain on your air conditioning system. In winter, solar roof ventilators can help prevent ice dams from forming by removing moisture from the attic before it condenses on the roof.
