GENERAL INFORMATION
How Whirlybirds Improve Roof Ventilation
A whirlybird is a wind-driven roof ventilator that removes hot, stale and moisture-laden air from your roof cavity. As it spins, it creates natural suction that extracts trapped air and allows fresh air to enter through additional whirlybirds, improving airflow without using electricity.
In Queensland’s heat and humidity, poor ventilation can cause extreme roof temperatures, condensation, mould growth and insulation damage. Proper roof vent installation helps regulate internal temperatures in summer while reducing moisture build-up in winter.
For residential, commercial and strata buildings, multiple units are often installed to ensure balanced ventilation across the entire roof space.

Commercial & Warehouse Roof Ventilation
Proper ventilation is critical for warehouses, factories and large commercial buildings due to wide roof spans and high internal heat loads. In Brisbane, most warehouses require approximately one whirlybird per 150–200m² of roof area, depending on insulation, internal heat sources and airflow restrictions. Larger or hotter environments may require additional units to achieve balanced extraction across the entire roof cavity.
Professional commercial whirlybird installation reduces heat build-up, improves air circulation and minimises condensation. This helps protect stock, machinery and structural components while reducing strain on mechanical cooling systems.
Apex Roof Vents also provides strata roof vent installation across Brisbane, ensuring shared buildings receive consistent, properly distributed airflow.
Whirlybirds for Metal Roofs
At Apex Roof Vents, we specialise in ventilating metal-roof homes across Brisbane and South East Queensland. Metal roofing can reach extreme temperatures in summer, transferring heat directly into the ceiling cavity. During cooler months, condensation can form beneath the sheets, leading to mould growth, damp insulation and long-term corrosion.
A properly installed whirlybird provides continuous airflow through the roof space, removing trapped heat and moisture before it causes damage. Most metal-roof homes benefit from approximately one whirlybird per 90m², with a minimum of two units recommended to achieve balanced ventilation. Larger roofs or properties with limited eave airflow may require additional units.
Wind-driven, quiet and low-maintenance, whirlybirds offer a cost-effective solution for improving indoor comfort and protecting your roof structure year-round.
Whirlybirds for Tile Roofs
Apex Roof Vents provides professional whirlybird installation for tile-roof homes across Brisbane and South East Queensland. Tile roofs can trap significant heat during summer, increasing indoor temperatures and placing extra strain on air-conditioning systems.
In winter, condensation becomes a serious issue when warm indoor air rises into the roof cavity and meets cooler air entering through tile gaps. This temperature clash creates moisture beneath the tiles, leading to mould growth, damp insulation, ceiling staining and potential structural damage if left unmanaged.
For effective airflow, most tile-roof homes benefit from approximately one whirlybird per 90m², with a minimum of two units recommended to ensure balanced ventilation across the entire roof space.
Properly installed whirlybirds provide continuous extraction of hot and moist air, helping regulate temperature, reduce condensation and protect your home year-round.
