WhirlyPro installs Australian-made solar roof
ventilators in Wollongong. Reduce heat & mould with 700m3/hr airflow. Free quotes. 10-year warranty.
Wollongong’s coastal humidity sits heavy for much of the year, and the Illawarra Escarpment traps warm, moist air over the city. That heat and moisture build up fast in the roof and make homes uncomfortable. WhirlyPro’s Australian-made solar ventilators pull more than 700m³ of hot air out every hour, keeping Wollongong homes cooler and drier on free solar energy.
Wollongong sits beneath the Illawarra Escarpment, which traps warm air against the coast. Summer days typically reach the mid-to-high 20s°C, and still, humid afternoons can occasionally push past 35°C. Roof cavities absorb this heat and radiate it into the home long after sunset.
Humidity is the bigger issue. Relative humidity climbs well above 60% in summer, and moisture-laden sea air keeps roof cavities damp. Without active airflow, this moisture condenses and drives mould growth, gradually damaging timber framing and insulation — especially in older weatherboard and brick-veneer homes.
WhirlyPro is built for this heat-and-humidity combination. Its solar-powered system with a smart thermostat extracts over 700m³ of hot, moist air every hour, even on still, muggy days — keeping homes more comfortable, protecting the roof from moisture damage, and running on renewable energy with zero ongoing costs.

“Our top floor was an absolute oven during the summer heatwaves. Since installing WhirlyPro, the heat is pulled right out and the air con doesn’t struggle anymore.”
“We had a real issue with trapped moisture and mould in our roof cavity. This solar fan sorted it out immediately and runs completely silent.”
“This active fan is vastly superior to our old whirlybirds. It starts up automatically as soon as the sun hits the roof and keeps the ceiling space cool.”
A whirlybird needs wind to spin. WhirlyPro is solar-powered and motorised, actively pulling 700m³ of hot air out per hour even on still days.
No. It runs entirely off its own solar panel — zero added to your power bill.
Yes. It runs on daylight, and the smart thermostat prioritises the hottest, most humid conditions.
No. It's sealed and weather-rated, drawing air out while keeping rain, insects, and debris out.
Depends on roof size and layout — we'll recommend the right number for your home.
