WhirlyPro installs Australian-made solar roof
ventilators in Newcastle. Reduce heat & mould with 700m3/hr airflow. Free quotes. 10-year warranty.
Newcastle summers are warm and humid, with daytime temperatures averaging around 26°C and heatwaves regularly pushing past 40°C. That heat and coastal 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 Newcastle homes cooler and drier on free solar energy.
Newcastle sits on the coast at the mouth of the Hunter River, giving it a humid subtropical climate. Summer highs average around 26°C, but heatwaves regularly push past 40°C, and roof cavities absorb that heat all day and radiate it back into living spaces well into the evening.
Humidity adds to the load. Coastal moisture keeps summer humidity high, and without active airflow that damp air becomes trapped in the roof space. Over time this condensation drives mould growth and gradually damages timber framing and insulation — a common issue in Newcastle’s older weatherboard and brick 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.
