Professional Whirlybird Installation Across Perth

Installing a whirlybird is one of the most effective ways to improve roof ventilation and control heat buildup inside your home. We install durable units that handle Perth’s heat, wind and dust without noise or leaks.

What does a whirlybird do?
A whirlybird helps remove hot air, humidity and condensation from your roof cavity. It spins using wind power, drawing out stale air while letting cooler air flow through vents or eaves. This reduces heat buildup, protects roof structure and makes your home more comfortable without increasing energy use.

Do whirlybirds really make a difference in Perth’s climate?
Yes. Perth’s hot summers and limited rainfall mean roof spaces can reach extreme temperatures. A properly installed whirlybird can lower roof cavity heat by several degrees, helping your home stay cooler and your air conditioner work more efficiently. It also prevents condensation during cooler months.

How many whirlybirds do I need for my roof?
The number of whirlybirds needed depends on your roof size, pitch and ventilation requirements. Smaller homes may only need one or two units, while larger or multi-storey homes may require more for effective airflow. We assess your roof and recommend the ideal number for balanced ventilation.

Can you install whirlybirds on any roof type?
Yes. We install whirlybirds on tile, metal and Colorbond roofs. Each material requires specific flashing and sealing methods to ensure a watertight fit. Our licensed roofers are experienced with all roof types and guarantee every installation is completed safely and securely.

Do whirlybirds work without wind?
Yes. While whirlybirds are powered by wind, even a light breeze is enough to keep them spinning. On still days, the natural rising heat in your roof cavity helps move air through the vents. This combination ensures consistent airflow and ventilation throughout the year.

Can whirlybirds leak during heavy rain?
Not when installed correctly. We use high-quality, weatherproof whirlybirds and seal them carefully to prevent leaks. Our team also checks flashing and surrounding areas for proper drainage. A properly fitted unit will stay watertight through Perth’s heaviest storms.

Do you repair or replace old or damaged whirlybirds?
Yes. We repair and replace noisy, seized or leaking whirlybirds across Perth. We inspect your current unit, determine whether it can be fixed or if replacement is better value, and carry out the work quickly and safely. All new installations include a performance and leak test.

Are whirlybirds noisy?
No. Modern whirlybirds are designed with sealed bearings that allow them to spin quietly, even in strong winds. If a whirlybird becomes noisy, it usually means the bearings are worn or debris has entered the vent. We can repair or replace it to restore silent operation.
