Whirlybird Installation Adelaide
Wind-driven roof ventilators that drop attic temperature 15-25C in summer.
Whirlybirds (wind-driven turbine ventilators) extract hot air from the roof space, dropping attic temperature 15-25C in summer. They're a low-cost upgrade ($250-$550 each installed) and a standard part of any Adelaide roof restoration or replacement.
When you need whirlybirds
- Attic gets very hot in summer

- Roof restoration in progress (good time to add)
What's included in a proper quote

- Whirlybird supply (Edmonds, Twista or comparable)

Adelaide-specific considerations
