Tweed Coast Whirly Birds
If your home gets uncomfortably hot in summer or you’ve noticed musty smells or condensation in the ceiling, your roof might not be breathing properly. At Cudgen Roofing & Guttering, we install whirly birds across the Tweed Coast to help homes ventilate naturally and stay comfortable year-round. These wind-powered roof vents are a simple, energy-free way to release trapped heat and moisture from your roof cavity, which can otherwise cause damage to insulation, framing, and ceilings. Whirly birds spin with the breeze—even a light one—and quietly pull out stale air, reducing heat buildup and improving airflow through your home. They’re especially useful in coastal areas like ours, where humidity and high UV levels can cause roofs to deteriorate faster without proper ventilation.
If your ceiling feels like it’s storing summer heat or you want a cooler, healthier home without running the air con non-stop, give us a call on 0402 540 929 and let’s talk about whirly birds.
Cool, Quiet & Built to Last
Whirly birds are a low-maintenance addition to any home—but when installed correctly, they make a noticeable difference. We work with a range of quality models to suit different roof types and colours, and we’ll help you choose how many you need based on the size of your roof and your home’s ventilation needs. Good ventilation plays a big role in keeping your roof cavity healthy—it helps control moisture, reduces heat buildup, and supports the performance of your insulation. We install whirly birds with care to prevent leaks, rattling or wind issues, so you get reliable performance with no fuss. The best part? They require no electricity and virtually no upkeep. Once fitted, they spin away quietly, keeping your roof space cooler in summer and drier in winter. That means less mould risk, better energy efficiency, and a more comfortable living environment.
Want to ventilate your home naturally and protect your roof from within? Call 0402 540 929 today to get started.
What do whirly birds do and how do they work?
Whirly birds are passive roof ventilation devices that use wind and thermal uplift to remove hot and moist air from your roof cavity. As the sun heats your roof space, the air inside rises and spins the turbine, creating a vacuum effect that pulls stale air out. Even a small breeze is enough to keep them spinning. This helps regulate temperatures inside your home, reduces the load on your insulation and cooling systems, and prevents moisture buildup that can lead to mould or structural damage.
Are whirly birds still a worthwhile addition to modern homes?
Yes, whirly birds are still a worthwhile addition to modern homes—especially in climates with high humidity or long, hot summers. Even if your home is well insulated, heat can still accumulate in the roof cavity and cause discomfort or higher energy bills. Whirly birds work alongside insulation to release that trapped air and improve energy efficiency. They’re particularly useful in newer homes with sealed rooflines and low natural ventilation.
Can whirly birds be installed on any type of roof?
Whirly birds can be installed on most common roofing materials, including metal (like Colorbond), tile, and even some flat roof systems. The key is using the right flashing and installation technique for the specific roof profile. Proper placement—usually near the peak of the roof—is important to maximise airflow and prevent leaks. It’s best to have a qualified installer assess your roof type and recommend the best setup.
