Roof Ventilation

Roof ventilation installation Brisbane & Sunshine Coast

Roof ventilators, also known as whirlybirds, are wind-driven turbines or impellers designed to extract the warm moist air that accumulates in the roof space between the underside of the roofing membrane and your home's ceiling.

Because hot air rises, the roof ventilators should be positioned at the highest point of the roof. Sadly, whirlybird installation has been done incorrectly in so many homes, with no one bothering to tell the homeowner that the installation of vents to the soffits of their homes will make the roof ventilators work more effectively.

Why is roof ventitlation important during Queensland summers?

The air temperature in the roof void in summer can reach twice that of the outside air temperature. The roof ventilator will draw out the hot air from the roof void, if you have vents installed in the soffits, in addition to extracting the hot air from the ceiling void. A roof ventilator will also pull the cooler air from the outside of the home in to the ceiling void, thus lowering the air temperature in the ceiling void.

You now have cooler temperatures in the ceiling void area being moved about by the action of the roof ventilator, which will in turn lower the temperature of the ceiling material and the airspace below thereby reducing the amount of work your air conditioner must do to reduce the temperature in the living area of your home. The end result: a lower electricity bill!
