There are so many to choose from, however in looking for the best roof vent singular for a house it is sort of a contradiction in itself.
What do you think one roof vent is capable of, the answer is very little or none at all. The roofspace of a house is generally a large area and can be quite complex, so to think that only one roof vent is going to cool the whole area of the roofspace and in turn make the house cooler in summer can be likened to the fact that pigs may fly.
This is not at all to refer that the layman is dumb or stupid, however obviously to those that are ill informed to inform them of what they should be looking for when they are looking for the best roof ventilation for their home.
SO YOU SHOULD BE SEEKING WHAT IS THE BEST ROOF VENTILATION SYSTEM FOR A HOUSE
In order for excessively heated air to evacuate the roofspace you will need one vent to let air into the roofspace and another vent to let the heated air to leave the roofspace, this is basic science.
Much the same as your take away cup of coffee which has a large hole to drink from and a small hole to allow air to enter, so it is easy to drink the coffee from, makes sense doesn’t it – air in coffee out.
It is the same process for roof ventilation air in stale air out, however depending on the size of your house will dictate how many pairs of roof vents you will need to remove the heat from the roofspace and cool the home. So you will need a series of inlets and outlets for your particular roofspace – generally for a tiled roof we recommend 4 for a small home, 6 for a larger home and so on. For a corrugated colorbond roof we recommend 2 for a small home, 4 for a medium home and 6 for a larger home.
So there you have it, the best vent for a house is actually a series of pairs of vents and these will work best if the vents are in the roof covering, this will become your roof ventilation system.
