Do whirlybirds and solar vents work?

The reality is a whirlybird is an extremely affordable and effective way to improve your roof ventilation.

On the Gold Coast and throughout Australia we all know the weather can get uncomfortably hot. If the heat builds up in your house, a whirlybird will create airflow and help reduce your air conditioning costs and improve comfort levels.

Ventilator Whirlybirds are wind-driven turbines designed to exhaust heat and moisture from the roof space without the use of electricity.

Our high quality, roof-mounted, aluminium roof vent combines modern design with practical features for guaranteed long-lasting performance. Constructed from light-weight aluminium, it comes with a 15-year warranty for lasting peace of mind and comfort.

Choose from 28 different colours to match your roof. View our selection of commonly used roofing colours.

Had a whirlybird removed and a new one installed by Allcoast Roofing Service - very happy with their service and workmanship. They replied to me quickly with a quote, suggested whirlybird colours to match my roof, and provided a timeframe for installation (which was met!). Installation was a breeze and the new whirlybird looks great. Thanks Wayne, appreciate your great service

SupaVent Whirlybirds

The number of roof vents you'll need will vary based on your roof size and reasons for ventilating. As a general recommendation, 1-2 whirlybirds is sufficient per 90^m2 of roof space.

However, for the best ventilating results, contact the Allcoast Roofing team. We can provide you with a quote for a solution customised to suit your needs.

Moisture in your home can be a destructive force, causing wood rot and encouraging mould and mildew. These in turn can trigger asthma and allergies. Edmonds roof ventilators expel moist air, helping to protect both the integrity of your home and the health of your family.

Whirlybird installation

SupaVent is ideal for tiled roofs, needing only one tile to be removed for installation. The UV- and temperature-stable light-weight plastic head, with its 250mm opening and stainless-steel bearings, provides a good alternative to WindMaster Whirlybirds and are ideal for homes affected by salt air.

Whirlybird installation cost

The cost for SupaVent whirlybird installation can vary depending on roof height, tin or tile. The cost starts at $330 inc. GST.

Solar Roof Ventilator

One solar roof ventilator removes 20 times the volume of air of one standard whirlybird and will keep removing hot air when the wind stops.

How much does a solar ventilator cost?

The cost of a solar ventilator is around $990 inc. GST.
