Did you know that hot air and moisture can build up in your roof space?
External heat enters your home through windows, doors, and the overall structure. This means the air in your house becomes hot. When this heat becomes trapped, which particularly happens in the roof area, the temperature of your home can become less comfortable, especially in certain climates.
What’s more, if moisture from humidity and dampness from appliances, such as dishwashers and showers, have nowhere to go and settle within your roof, it may create issues such as mould. This has the potential to lead to increased structural and health risks.
So, how do you fix these issues? Roof ventilation can be a great solution. Find out more about roof ventilation, the different options available, and how Skylights WA can help.
What is The Purpose of Roof Ventilators?
Roof ventilation aims to remove the hot air that gets trapped in your roof space. This can be done in various ways and depends on the type of ventilation that is installed. When the airflow improves, the temperature typically reduces, and the moisture has less chance of building up.
During cooler periods, roof ventilation still helps to regulate the temperature. Rather than continuing to pull hot air out to reduce the temperature, some options stop ventilating so that your home can be cosier.
How Do Roof Vents Work?
There are several different ways to ventilate your roof area. Essentially, roof ventilation options promote airflow in a manner that keeps unwanted elements, such as debris and rain, from entering the roof.
Different types utilise different approaches to ventilation. This can be based on methods such as changes in air pressure or creating a suction-like effect. The system may involve different equipment, such as exhaust, ridge, intake or static vents, or wind turbines.
Three Different Methods to Ventilate Your Roof
Roof ventilation comes in different styles and designs. From vents to fans, from sun-powered to wind-powered, there are many options to choose from so that you can find the right type for your house.
Some options for roof ventilation include:
1. Solar Roof Ventilation
This type of roof ventilation utilises a method that promotes airflow using solar energy.
This option often involves a thermostat to regulate the internal temperature by adjusting or shutting off the ventilation according to your preferences.
We have a great range of solar roof ventilation options. We can assess your roof and determine which is best for you. Our experienced team will carry out a comprehensive installation and can help with maintenance in the long term. Please call to discuss any questions you have about solar roof ventilation.
2. Wind-Powered Ventilation
Roof ventilation that uses the wind typically involves a cylindrical turbine. The moving air enters and as the pressure differs inside the vent, it begins to spin. This generates the power that supports the ventilation, meaning there are no running costs.
Whirlybirds are one type of wind-powered ventilation that is commonly used for houses. They can be a cheaper option but may be damaged quite easily due to bad weather or falling debris.
3. Electrical Roof Ventilation
As the name suggests, this option utilises electricity to ventilate your house. The ventilation powered this way may involve different methods, such as vents or mounted motor-run fans.
This option involves the ongoing costs of electricity but avoids the potential risk of not functioning properly due to a reliance on uncontrollable elements, namely, the solar energy and the wind.
Considerations For Roof Ventilation
Choosing the most suitable type of roof ventilation for you can come down to various factors such as your preferences, budget, and goals. Other aspects revolve around your type of house and roof.
Some roofs will offer better ventilation options than others. When we assess your house and recommend what type of ventilation may suit you, we consider:
Roof Structure
This involves factors such as what the roof is made up of and its thermal properties. The size and pitch of the roof are also pivotal in the ventilation decision, as well as the roof cavity’s volume.
Insulation
Whether you already have insulation or are thinking of putting some in, this affects the decision of which roof ventilation to go with as it typically helps to reduce the build-up of hot air.
Roof Sarking
Sarking is a layer that is placed underneath roofing tiles. It aims to increase the positive effects of insulation by adding more protection against external heat. It may have a negative effect on roof ventilation because the air may get trapped, so if sarking is present, it needs to be assessed.
