“Thank you Chris for a great job, a professional service from quote to completion. Highly recommended.”

“Yes, Chris was very straightforward, friendly and completed the job in a very short time. We’d been very concerned as we called tradies before, but they never turn up, so Chris has helped us massively. I definitely recommend him, as he gives peace of mind by putting warranty on the job he completes”

Whirlybird FAQs
How many whirlybirds do I need?
It depends on your roof size and cavity volume — as a guide, one whirlybird per 90m² of roof space is typical. We’ll assess this for you.
Do whirlybirds need power?
No — they’re wind-driven and require no electricity, so there’s nothing to wire in or maintain.
Are whirlybirds noisy?
A quality whirlybird, properly installed and maintained, runs virtually silently.
