The sweltering summer heat usually causes discomfort in your home and in most cases, you are forced to turn on your air conditioning system.
However, the air conditioning system cools the interior of your house, but do you know that the roof traps the greatest percentage of heat?
Against this background, it can be observed that roof ventilation options such as whirlybirds can help you solve the problems related to heating of your roof since they work all year round.
The only issue is that the effectiveness of whirlybirds depends on different factors that you need to know first before you consider this option.
With that said, read on to learn how the installation of whirlybirds on your roof can help you resolve heat-related issues in your home.
Why Whirlybirds for Your Roof?
Proper ventilation of your roof can make the inside of your home comfortable, though they have no equal power like air conditioners.
Professionals at Freemantle Roofing Services explain how whirlybirds can help reduce the heat inside your roof during the hot summer season.
Essentially, whirlybirds provide ventilation of air in the roof which helps you to cut down on the expenses of using an air conditioning system.
Heat builds up in your roof during the hot summer days, but whirlybirds will help extract the trapped hot air from the roof.
At the same time, whirlybirds also help to draw cool fresh air from outside.
The other notable aspect of whirlybirds is that they help circulate fresh air during the winter season when temperatures are generally low in different places.
Moisture build-up during this season can damage your ceiling, but with whirlybirds, fresh air is constantly circulated within your roof.
This will help to keep your roof dry while at the same time preventing rot and mold build up in your roof.
The major benefit of installing whirlybirds on your roof is that they are wind-driven and, therefore, cost-effective.
Factors to Consider When Installing Whirlybirds on Your Roof
As you are now aware, whirlybirds do not work like air conditioners in your homes.
The effectiveness of whirlybirds on your roof depends on its type and surface area.
If your roof is large, then you need multiple whirlybirds to effectively cool the interior part.
One whirlybird may not effectively ventilate air from your roof.
The other thing is that your roof should have a sarking system that helps prevent water from getting inside and it prevents a good seal for the whirlybirds.
The effectiveness of the whirlybird can be affected if the roof has no sarking system since the gadget will suck air from outside through the gaps on your tiles.
The speed of the wind also determines the effectiveness of the whirlybirds.
Disadvantages of Whirlybirds
Commonly, whirlybirds are wind-driven so you should not overly rely on them for cooling your home.
When there is no wind, it means that your whirlybirds will not operate.
Homes located in windy areas get the most benefits of whirlybirds, so you should not take them as substitutes for conventional air conditioners.
The other downside of whirlybirds is that they can be noisy as then turbines tend to rub on other materials as they turn.
Though cost-effective, whirlybirds are not very efficient like air conditioners.
A whirlybird can hardly reduce the humidity inside the house.
Studies indicate that it will take more than ten whirlybirds to cool a standard home.
Considering the size of an ordinary home, it is not worth investing in this outdated technology.
Whirlybirds are also prone to malfunctioning if they trap different obstacles.
Therefore, you should constantly inspect them which can be unnecessary labor.
The whole vent may need to be replaced if the whirlybird is badly damaged.
To avoid this, you may need to get solar-powered whirlybirds, but this can be costly considering that there are better cooling options for your home.
In other words, whirlybirds were good in the past, but they have been overtaken by new technology.
Whirlybirds help to ventilate your roof which makes your home comfortable during the hot summer days.
However, you should know that a whirlybird is not a substitute for an air conditioner since it only sucks hot air from the roof.
It does not cool the entire house but can lower the impact of the heat from the sun.
All the same, the effectiveness of whirlybirds depends on the size of your roof.
When the surface area of your roof is large, it is a good idea to install multiple whirlybirds so that they can suck out more air.
