Whirlybirds are a common form of roof ventilation because they’re cheap, easy to install and you can effectively “set it and forget it”. If you have an adequate number of whirlybirds (one or two won’t be effective unless your home is very small), they may provide an appropriate amount of ventilating and cooling. But if energy efficiency is important to you, we highly recommend considering a solar vent
Whirlybirds remove precious heat during the winter, leaving your home colder, which leads to higher heating costs. Furthermore, they are very inefficient at cooling your home during the summer if it’s not consistently windy. This is especially true in hot and dry climates. This is why it’s more sensible and practical to consider a thermostatically-controlled Solar Roof Exhaust Vent.
A Solar Roof Exhaust Vent contains a small solar panel which powers an exhaust fan inside the frame. It comes with a functioning thermostat and will only function when internal roof temperatures rise above 28 degrees Celsius, so it’s only working when you actually need it to.
A Solar Roof Exhaust Vent does the same job as a whirlybird, but better. It provides ventilation which prevents the accumulation of condensation and moisture, which can severely damage your roof and roof framing. Believe it or not, a single Solar Roof Exhaust Vent removes as much hot air as 10 whirlybirds. They’re also quieter than whirlybirds, and operate all-year round. Although they don’t work at night due to the lack of sunlight, this is typically a non-issue because they’re most needed during the day when the sun-rays are heating up your roof and attic.
For optimal performance, we recommend installing a Solar Roof Vent at the highest point of your roof. Contact us to learn more about pricing, installation and other considerations to provide the most energy-efficient ventilation option for your home.
