Are you sick and tired of these long hot summers that just seem to be getting more intense?

Have you got an ongoing battle against mold in your house?

You may be surprised that there is one easy solution to both of these problems – roof vents!

Roof ventilators, also commonly referred to as whirlybirds, are as iconic on Australian houses as a Hills Hoist is in the backyard. So why do so many Australian houses have roof vents? Quite simply, because they work.


Summer Benefits

By utilising a combination of natural convective air movement and wind power, roof ventilators are able to remove heated air from your roof cavity. The roof area can get extremely hot in summer, which results in heat being radiated throughout your entire house. By actively extracting heated air from your home you will be able to reduce the amount of electricity that you need to spend on cooling throughout summer. The Australian Building Sustainability Index promotes roof ventilators for “reducing the cooling load of your dwelling by allowing hot air and excess moisture in the roofspace to escape.”

Winter Benefits

If you live on the Eastern Coast of Australia then you are surely familiar with mould, and the health conditions that it can exacerbate including respiratory problems and severe allergies. But fighting mould can seem like an unwinnable challenge! After using even the most intense cleaners, the mould returns after a few weeks. But there is a secret weapon! Mould grows in moist environments, which is why it is so prevalent in residential houses in Brisbane, Sydney and Melbourne. The humid air in bathrooms, kitchens and bedrooms is the ideal environment for mould. Roof ventilators are an effective means of extracting moist air and replacing it with fresh flowing air. Many homeowners are surprised at the difference that a roof ventilator can make in regards to retarding the growth of mould.


What type of roof ventilator provides the most benefits?

There are a lot of different types of roof ventilators on the market that offer different advantages and disadvantages. So it is important to research and find the ideal solution for the unique requirements of your property.

Some of the most important points to investigate include:

Materials – Is the roof ventilator constructed from poor quality materials? Are the bearings plastic or steel? Plastic bearings degrade quickly and can lead to poor performance and noisy operation.

Design РDoes it come with a guarantee? Does it require regular maintenance? Does it operate silently?

Price – You get what you pay for. There are a lot of cheap imports from South East Asia, but the build quality is terrible. Not only are they incapable of extracting sufficient air, but they are also flimsily constructed and can leak rain into your roof. Don’t risk expensive water damage to your house, instead¬†invest in a quality Australian made roof vent that will help you save hundreds off your electricity bill.
