When you think about your roof, you’re probably focused on how it looks and whether or not it’s leaking. Chances are you haven’t considered much beyond that, but there’s a lot more to your roof and roofing system. Roof space insulation and ventilation play a crucial role in maintaining the health and lifespan of your roof.


The Role of Roof Ventilation in Temperature Regulation

In Summer

A roof ventilation system works by drawing in fresh air into the roof space while expelling heat and moisture. This process reduces the temperature difference between the air inside and outside the roof space. It’s especially important in humid climates like Australia, where everyday activities such as doing laundry, taking showers, and washing dishes, combined with the daytime heat, can cause moisture levels to rise and temperatures to soar up to 70 degrees Celsius.

A good ventilation system will reduce the heat load on your building by expelling the hot air that builds up in your roof space and replacing it with cooler air from outside. This will increase the longevity of your roof and improve the efficiency of any existing heating or cooling systems, helping you lower your energy costs.

In Winter

During winter, a proper roof ventilation system remains just as important. While it may seem counterintuitive to allow fresh air into your roof space when you’re trying to keep your home warm, ventilation still plays a crucial role in maintaining the health of your roof.

In winter, moisture can accumulate in the roof space due to various factors such as condensation from everyday activities, like cooking and showering, or from roof leaks. This moisture can lead to the growth of mould and mildew, which can damage the structural integrity of your roof and compromise the insulation.

A well-designed ventilation system actively extracts this excess moisture, preventing condensation and mould growth.

By maintaining a balanced airflow and preventing moisture build-up, roof ventilation in winter helps preserve the lifespan of your roof, preventing costly repairs and ensuring the overall comfort and well-being of your home.


Different Types of Roof Vents and Their Functions

There are multiple types and styles of roof vents available on the Australian market, each working in different ways and varying in their effectiveness. The ideal ventilation system must account for individual differences in a building’s structural design, which affects how much airflow it may need.


Let’s take a look at a few common vent types you can choose from:

  • Whirlybirds: Also known as turbine ventilators, are a type of passive ventilation system commonly used in residential and commercial buildings. However, their efficiency is limited due to their reliance solely on wind power for operation. Compared to powered ventilators, whirlybirds can only move a relatively small amount of air, making them less effective in providing robust ventilation.
  • Eave Vents: Eave vents are passive ventilation components installed in the eaves or under the roof overhang. These vents allow fresh air to enter the roof space from the outside.
  • Ridge Vents: The ridge vent, placed at the roof’s peak, acts as an air exhaust vent. It requires cutting an air slot in the roof deck and then securing the ridge vent to cover the slot.
  • Power Ventilators (PAVs): Roof and gable-mounted, power ventilators have electric motors that turn large fans to drive hot air and moisture out of the roof space.
  • Solar Roof Ventilators: These innovative vents harness solar power to effectively ventilate your roof space. They use solar energy to power the fans, expelling hot air and moisture while reducing your energy consumption. Solar-powered roof ventilators like Solar Whiz run with zero operating costs and improve the performance of other electric heating or cooling systems, helping you to cut down on your energy use and costs.


Whirlybirds, eave vents, ridge vents – These systems rely on passive airflow and move very little air. Relying on passive air movement through wind power (like with whirlybirds) and heat convection are ineffective ways to ventilate your home. It is our strong suggestion that you consider active ventilation solutions in order to achieve meaningful results.


The Consequences of Improper Ventilation

It’s crucial to install a ventilation system that maintains a balance between intake vents and exhaust vents. Poor ventilation can cause serious problems for the health of your home. Excess heat in your roof space can result in warped structures and makes it harder for air conditioning systems to work properly. Bad ventilation can also allow mould and mildew to grow which also causes structural problems and compromises indoor air quality.
