Different Types of Roof Vents

Having adequate ventilation in your roof is crucial to maintaining a balance between the environment inside and outside your house, preventing the build-up of warm air and moisture in your attic and preserving the structural integrity and condition of your roof. With the right kind of roof vents, you can create a path for heated air and moisture to escape from within the vicinity of your house. Roof vents come in a number of different shapes and sizes. Some also have distinct features that make them ideal for certain specific situations. Before you venture out to buy roof vents for your house, it is important to know about the different types of roof vents available in Australian market. This will help you to decide which ones would fit your needs the best.

  1. Box Vents or Flat Vents are static vents and have no moving parts. They are among the simplest kinds of roof vents, allowing air to escape through natural convection. These are typically installed over an opening cut into the roof and can be purchased either in metal or plastic. Due to limited efficiency, in many cases the number of box vents required to vent a house can be on the higher side.
  2. Wind Turbine ventilators are dependent on the wind for their spinning action which can move out larger volumes of air than simple static vents. It is recommended to buy only those models which are high-quality and offer noise free operation.
  3. Ridge Vents cover the entire length of the horizontal edge of your roof. These are high performance static vents which can affect even distribution of temperature.
  4. Power Vents employ the use of motors which operate large fans to drive the hot air out of your house. These are particularly efficient and need electricity to operate. You can either choose to hardwire these into your mains electric supply or get a model which comes with a dedicated solar panel to power it.
