Whirly Bird Replacement Across Brisbane — From $350 Installed

Every whirly bird eventually wears out. The bearings seize, the sheet metal corrodes, or a summer storm bends the vanes. When that happens the unit stops moving air and your roof cavity goes straight back to trapping 60–70°C heat all summer. Replacing it is quick and inexpensive — whirly bird replacement starts from $350 per unit, and in most cases the new unit drops straight into the existing hole.

Mike replaces whirly birds, roof turbines and roof ventilators right across Brisbane — northside, southside, western suburbs and bayside. He is owner-operated and fully insured, so the person who quotes the job is the person on your roof.

Signs You Need to Replace Your Whirly Bird

• It has stopped spinning — on a breezy day a healthy turbine always turns. A stationary one has seized bearings and is doing nothing.
• Squealing, grinding or rattling — worn bearings, or a loose dome. It will only get louder.
• Rust streaks on the roof — the unit is corroding and the base flashing is often going with it.
• Storm damage — dented dome, missing vanes, or a unit that has been lifted and re-seated crooked.
• Water marks in the ceiling below the vent — the flashing seal has failed.
• It is simply old — cheap imported units start failing at 3–5 years. Quality Australian units run 15–20 years.

Rusted Whirly Bird Replacement

Rust is the number one reason Brisbane homeowners replace a whirly bird. Our humidity, summer storms and coastal salt air work through thin imported sheet metal quickly. Once rust reaches the base flashing you have a leak risk as well as a ventilation problem, so replacing the whole assembly — turbine, base and flashing — is the correct fix. Painting or patching a rusted unit is a waste of money.

Noisy Whirly Bird Replacement

A correctly installed quality whirly bird is virtually silent. If yours squeals on windy nights or grinds as it turns, the sealed bearings have worn out and cannot be re-greased. Replacing a noisy whirly bird takes about 30–45 minutes and starts from $350 — most people are surprised how cheap the fix is after putting up with the noise for a year or two.

Damaged & Broken Roof Vent Replacement

Storm-damaged and broken roof vents should be dealt with promptly. A dented or partially detached unit not only stops ventilating, it can lift further in the next big blow and take roof sheeting or tiles with it. Mike carries the common sizes on the truck, so damaged whirly bird replacement is usually a same-visit job once the quote is agreed.

Roof Vent Replacement Cost in Brisbane

Roof vent replacement cost depends on how many units you are swapping and whether you stay with a wind-driven turbine or move up to a solar vent:

• Single replacement (existing hole reused): from $350 installed
• Each additional unit in the same visit: +$300 — two units $650, three units $950
• Upgrade to a solar-powered roof vent: from $750

Prices include GST, the new unit, removal and disposal of the old one, new flashing and sealant. There is no call-out fee and the phone quote is free.

Supply and Install Replacement Whirly Bird — What's Included

• Removal and disposal of the old whirly bird or roof ventilator
• Supply of a new quality Australian-made unit (Edmonds or Ventair)
• New base flashing profiled to your roof type
• Stainless steel fixings and roof-grade sealant
• Repositioning closer to the ridge line if the original placement was poor
• Clean-up and removal of all packaging and old materials

Tile Roof Whirly Bird Replacement

On terracotta and concrete tile roofs, Mike lifts the surrounding tiles, removes the old flashing, and beds a new flashing under the tiles above so water runs over the top of it rather than into the join. Done properly, a tile roof whirly bird replacement is completely watertight through the heaviest Queensland downpour. Mike carries flashing profiles to suit the different tile brands found across Brisbane.

Metal Roof Whirly Bird Replacement

Colorbond, zincalume and corrugated iron roofs are quicker to work on. The old unit is unscrewed, the sheet is checked around the penetration for corrosion, and the new base is fixed down over a purpose-made EPDM gasket and sealed. Where possible Mike colour-matches the replacement unit to your Colorbond roof colour.

Roof Turbine & Wind Turbine Roof Vent Replacement

"Whirly bird", "roof turbine", "turbine vent", "wind turbine roof vent" and "roof ventilator" all describe the same thing — the spinning dome on your roofline. Whatever you call it, Mike replaces it. Larger 450mm turbine ventilators used on sheds, warehouses and high-pitched roofs are replaced the same way as residential units, just with heavier flashings.

Roof Vent Upgrade — Getting More From the Job

A replacement is the natural moment to fix a ventilation system that was never quite right. Common upgrades when replacing old whirly birds:

• Add units — the rule of thumb is one whirly bird per 50 m² of roof space. Many older homes were fitted with only one or two.
• Go larger — a 450mm turbine moves considerably more air than a 300mm on a big or steeply pitched roof.
• Move them higher — units fitted low on the slope never reach the hottest air. Replacement is the time to bring them up near the ridge.
• Upgrade an old whirly bird to a solar vent — see solar whirly bird replacement if your home sits in a sheltered, low-wind position.

Residential & Commercial Whirly Bird Replacement

Residential whirly bird replacement covers houses, townhouses, Queenslanders and units across every Brisbane suburb — typically one to four 300mm turbines per home.

Commercial whirly bird replacement covers warehouses, workshops, factories, sheds and strata buildings, usually with larger turbines fitted in rows along the ridge. Mike is fully insured for commercial work. Send through the unit size and quantity and he will price the job over the phone.
