WHIRLYBIRDS MANDURAH

A whirlybird is a roof ventilation device that uses wind power to rotate a turbine and expel hot air and moisture from your roof cavity. It operates without electricity, making it an eco-friendly solution for improving air circulation. By removing trapped heat and humidity, whirlybirds help regulate indoor temperatures, reduce the risk of mould, and prevent structural issues caused by condensation. This cost-effective ventilation system is especially beneficial in regions with warm climates, like Mandurah.

The number of whirlybirds your roof requires depends on several factors, including the size of your home, the pitch of your roof, and the level of ventilation needed. As a general guideline, one whirlybird can effectively ventilate up to 50 square metres of roof space. For larger homes or properties with specific ventilation challenges, multiple units may be recommended. Our team at Westcoast Roofs will assess your property and provide tailored advice to ensure optimal airflow and efficiency.

Absolutely! Whirlybirds help reduce energy bills by improving roof ventilation and regulating indoor temperatures. During hot weather, they remove trapped heat from the roof cavity, making your home cooler and reducing the workload on your air conditioning system. This results in lower energy consumption and more consistent indoor comfort. Since whirlybirds are wind-powered, they also operate at no additional cost, making them a highly cost-effective investment in energy efficiency.

High-quality whirlybirds are designed to operate quietly, even in strong winds. Modern models use precision engineering and durable materials to minimise noise and ensure smooth rotation. Noise issues can arise if the whirlybird is improperly installed or damaged, which is why professional installation is essential. At Westcoast Roofs, we ensure proper placement and secure installation to guarantee quiet operation and long-lasting performance.

Whirlybirds are built to last, with a typical lifespan of 20 years or more when made from high-quality materials such as aluminium or stainless steel. They require minimal maintenance, but it’s advisable to have them inspected periodically to ensure they remain in good working condition. This includes checking for debris, loose fittings, or any damage caused by extreme weather. Regular maintenance helps maximise their efficiency and extend their lifespan.
