Roof Ventilation Perth

Roof ventilation is a crucial factor in creating home comfort. Working hand in hand with insulation, whirlybirds and vents keep you cooler in the Summer. Without ventilation, in the warmer months your roof acts as a giant radiator. This heat gets trapped in your home, leading to warmer temperatures. Roof ventilation works hand in hand with your insulation to provide comfort.
Not only is roof ventilation keeping your home cooler, but it works year round. In the winter, lack of air flow will lead to problems. Moisture gets trapped in the roof, creating mould and mildew build up. Ventilation allows the moisture to evaporate, keeping your roof space dry.

Air Conditioning Efficiency with Roof Ventilation

In the summer, most Perth homes rely on duct air conditioning. Without ventilation, your roof space can exceed 55-60 degrees in the hotter months. Your air conditioning is having to push cool air through your very hot roof space!
With adequate roof ventilation, your roof space can be 8-12 degrees cooler. This translates to a 15-20% increase in the efficiency of your air conditioning. Your then running your air conditioning less, which means more comfort and less power.

Ollie came round last Saturday morning to install our new roof vents. Very polite and was done in an hour. Very happy with the work and I'm sure they'll make a huge difference. Would be happy to recommend.
