Are you considering installing a whirlybird and asking yourself whether they really work? The short answer is ‘Yes’! They are very effective at removing hot air and roof ventilation while keeping your home cool during hot summer months. Since they depend on airflow, they deliver the best results in windy locations, and they are a popular addition to WA homes.
The Key Benefits of Whirlybirds
During sizzling summer months, your roof can absorb a lot of heat which then accumulates inside your house. Some roofing materials such as Colorbond are less prone to heat, especially if you select light shades which tend to absorb less sunlight. Made from waterproof materials and available in Colorbond colour to match your roof, whirlybirds are practical and aesthetically appealing. Providing a simple, energy-efficient solution, they can help you ventilate your home by using pure wind power. When teamed with other ventilation devices, whirlybirds are the crucial element of an impactful cooling system. The main benefits include:
- Improving air quality
- Removing excess heat
- Lowering energy bills
- Helping eliminate mould
- Easy and cheap whirlybird installation
How Do They Work?
Whirlybirds boast a simple but effective mechanism. As the wind is blowing, the ventilator is spinning and removing hot air as well as water. It creates a vacuum which captures hot air and moisture and expels it from your home. The result is a cooler and significantly less humid home. Of course, the effectiveness of the whirlybird depends on the amount and strength of the wind. If the wind speed is about 8km per hour, the ventilator can remove about 10 cubic meters of hot air per minute. The larger the whirlybird, the more efficient the turbine will be! If you are not sure whether this mechanism is suitable for your location in WA, ask your whirly bird installer for professional advice.
How Many Whirlybirds do You Need?
The more whirlybirds you install on your roof, the more powerful the cooling effect is going to be. One is probably not enough to make a significant impact. After inspecting your house, your local whirlybird installation specialists will be able to tell you how many turbines you need and where you need to place them to achieve the best results. Perth homes typically require between two and four ventilators:
- For a 1-2 bedroom house, you’ll need 2 whirlybird units
- For a 3-4 bedroom house, you’ll need 3-4 whirlybird units
- For a 4-5 bedroom house, you’ll need 4-5 whirlybird units
Do You Need to Install Whirlybirds on Your Roof?

If you are looking for an energy-efficient way to keep your Perth home cool throughout summer, whirlybird turbines are the perfect solution. They work well in windy areas, and they pair well with Colorbond roofs. Since they are available in a range of classic and contemporary shades, you are bound to find a design that matches the style of your home.
