Roof Ventilation/Whirly Birds

A major roofing concern that all homeowners should be aware of is the need to properly ventilate the roof or attic of their home. The primary concern in roof cavities is the need to regulate the amount of moisture found in attics and roofs. Without proper ventilation, moisture can collect in the roof; over time this can cause the growth of mildew and mould as condensation collects without anywhere to go. When a roof is properly ventilated, it usually results in lower temperatures in the roof, which is an additional benefit you can enjoy from correcting this problem.

During the summer months, temperatures in roof spaces can reach levels as high as 60ºC. This causes heat to radiate downwards, causing discomfort in living areas. Cooler months can be just as much of a problem as water vapour from cooking and showers, as well as humidifiers, is drawn into roof spaces, condensing to form as much as 12 litres of moisture per day. This in turn causes mildew on walls and ceilings, which can contribute to a damp environment.

Fortunately, there are solutions to preventing moisture from gathering in the roof of your home. An effective ventilation system will address the heat and the moisture. Supreme Roofing Group can solve the problems with the installation of an adequate ventilation system that will do the hard work for you.

Whirlybirds are dome-like fans that sit on the roof of your home and spin with wind from the environment (passive system) or utilise an internal fan to run continuously (active system). As the fan spins, it draws warm air up into the fan from the room and pulls it out of the roof into the exterior atmosphere. This system is simple, effective and cost-efficient.
