Skylights WA have a range of solar powered, wind powered and electrical ventilation solutions to freshen your home or commercial premises. Our systems are designed to extract hot and moist air so you can breathe easy.
How Roof Ventilation Works
Roof ventilation aims to free the hot air and moisture that settles within the roof space. Different methods can achieve this, and choosing the right one requires assessment of your roof type, climate, budget, and aesthetic preferences.
There are three common options used to force the air and trapped heat out of the roof cavity. Within these options, you can choose from equipment and designs such as exhaust vents, fans, static or ridge vents, or turbines.
Solar Ventilation Systems
Solar roof ventilation is powered by energy from the sun. Due to its energy storage capability, it can function day or night and on sunny or cloudy days.
A thermostat is incorporated in most designs to monitor the internal temperature of the roof space. This prompts the ventilation to adjust or turn off in accordance with your preferences and requirements.
Wind Powered Ventilation Systems
Wind-powered roof ventilation utilises changes in air pressure to function. This means it always requires air movement but has no ongoing costs.
The wind enters a cylindrical, dome-shaped turbine. The pressure of the air outside and inside differs, which makes the device within turbine spin, generating air flow within the roof space.
Electric Ventilation Systems
Electric roof ventilation uses electricity to work. Although it requires ongoing running costs, this avoids the potential risk of ventilation not working due to uncontrollable elements, such as the wind.
Ventilation may be carried out with options such as mounted motor-run fans.

Benefits of Roof Ventilation Perth
There are several reasons why roof ventilation in Perth homes can be advantageous. These can include:
Removal of Hot Air
When external heat enters your home, it heats the air inside. Add in the internally generated heat, such as from people and appliances, and you have hot air rising towards your ceilings.
Without good airflow, this can lead to hot and uncomfortable living areas. Roof ventilation can decrease the temperature by releasing unwanted heat. Some may pull in cool, fresh air, too.
Removal of Damp Air
Air inside a home can become moist due to various sources such as environmental humidity, bodies, dishwashers, and showers.
If the damp air has nowhere to go, it can get trapped within the roof space and the moisture can settle.
Roof ventilation can decrease the risk of structural damage and health issues due to factors such as mould development caused by moist air.
Cost Saving
When your roof space is cooler due to good roof ventilation, your home becomes cooler.
This means you may be less dependent on appliances such as air conditioning and fans, which is better on the environment – and your wallet!
Versatile Designs
There is a lot of choice when it comes to roof ventilation, which means you can find a type that suits your preferences.
Select from different materials, types, sizes, and functionality to suit your home and budget.
Energy Efficiency
When there is adequate roof ventilation in the house, your air conditioning unit does not have to work as hard against the trapped hot, moist air.
Roof ventilation may improve the efficiency of your air conditioning by 15-20%, which can have a positive impact on the environment and your electricity bills.

Breezeman™ Solar Powered Hybrid Extraction Fan
Breezeman™ is a highly efficient range of Solar powered and Solar/240v powered Hybrid roof extraction fans, to suit homes, sheds, warehouses, where ever there is a requirement for day time or 24hr extraction of unwanted heat or emissions/stale air, or general improved airflow.
Solar powered roof extraction fans need to face true North in Australia to operate effectively, towards the optimal direction for solar irradiance. The PV module generates energy and directly discharges it directly to the electro-magnetic brushless motor, which drives the optimally angled fan blade. This is a highly efficient and reliable use of solar energy. The product has a long useful life, and has no ongoing operating costs!
Breezeman™ is available in the following models:
- Breezeman™ BM700-PV–10 watt PV only – daytime purging – extracting 700m3 per hr +/- 10% suitable for homes/sheds/Shire facilities
- Breezeman™ BM700-PV-10watt/240V Hybrid – for any time purging, extracting 700m3 per hr +/- 10% suitable for homes/sheds/Shire facilities
- Breezeman™ BM1800-50 watt PV only – daytime purging, extracting 1800m3 per hr +/- 10% suitable only for large commercial/industrial applications.
A 5 year Warranty covers the PV module and the motor.
FAQs About Ventilating Your Roof Space
Will roof ventilation make my house cold in winter?
Roof ventilation decreases the temperature during hot days and summer months. However, this can be adjusted. Due to clever technology, some types of roof ventilation, such as solar-powered roof vents, can monitor the temperature and switch off when it drops below the desired number. This means your house can remain cosy when you are running the heater or have the fire on while retaining the option to begin ventilation when the air temperature becomes too high.
Does my house need roof ventilation?
Most houses could benefit from roof ventilation, especially those in the stifling Western Australian climate. Aside from the house feeling uncomfortably hot, signs that may indicate roof ventilation could be useful include:
- Mould on the ceiling.
- Warped wood panels in the roof space.
- Increased use of air conditioning.
- High electricity bills.
Can I install roof ventilation myself?
Most types of roof ventilation systems require a professional for installation. Some designs require complex connections, including electricity wiring, while others may be difficult to deal with if you are not used to the process. Furthermore, it is extremely important that debris and the weather elements cannot get into your home through the ventilation. Subsequently, it is generally best for roof ventilation installation to be carried out by an experienced professional.
Can roof ventilation get damaged?
