Reasons Why Whirlybird Roof Vents are Very Popular in Many Homes

If you have been wondering why you should choose whirlybird roof vents for your home, the simple answer is right here. Browse for all the reasons why whirlybirds are preferred.

The structural integrity of your roof determines how long your home remains structurally intact. Once your roofing system begins to fail, it affects the rest of the house. One of the significant issues facing roofs is the heat trapped during the hot months.

The warm air then makes its way to the house and causes a lot of discomforts and poses potential risks to all appliances you have in your home.

There are many models of roof vents that many homeowners can choose. Turbine vents, also known as whirlybird roof vents are on that list. Many people today opt for the whirlybird that installs on the roofs ridge and helps eliminate all heat from the roof.

Types of Whirlybird Roof Vents

There are two main types of turbine vents available in the market. They are both equally efficient and reliable.

• Passive Whirlybird

Passive whirlybird vents are a wind-driven type of whirlybird.

The wind speeds determine how fast the turbines on the ventilation move.

Passive whirlybird roof vents are very affordable when looking to save energy costs.

• Active Turbine Vent

The active whirlybird is always rotating regardless of wind speed.

The vent utilizes mechanical turbines and creates a vacuum on the roof to keep away any heat from the roof cavity.

There are no electric costs attached to the use of the active whirlybird roof vent.

Whirlybird roof vents are an affordable roof ventilation solution for many homeowners. Since whirlybird turbines are wind driven, there are no energy costs incurred. The turbine vents run as long as there is wind blowing and do not utilize electricity.

IV. Solve mold problems
Humidity in the house causes the formation of mold which in turn converts your home into a moldy atmosphere that is unhealthy and dangerous. With turbine vents, you do not need to worry about dampness in your home.

Do Whirlybirds Cool the House?

Whirlybirds have the principal purpose of preventing the accumulation of heat on the roof that then transfers to the house. Turbine roof vents are however not air conditioners.

They do not provide any cooling effect to your home.

What the whirlybird roof vents do is provide transcendent air circulation which allows for the removal of hot air in your house. They offer excellent ventilation and ensure that your roof space remains heat free.

Whirlybird Installation

How Whirlybird Works

Once the installation process is complete, wind blowing rotates the vents by blowing through the turbines. Continuous rotation of the vents creates a vacuum on the roof. All hot air from inside the house gets sucked up into the whirlybird, and then the vents expel this warm air.

Maintaining the whirlybird roof vent is easy. They can work efficiently for decades without requiring much maintenance. Turbine vents are like exhaust fans that suck up hot air and then release it.

The turbines, therefore, have flaps that open the wind begins blowing into them. If your whirlybird shows signs of leakage, you do not necessarily need to replace the entire turbine vent.

The type of roof installed can affect the efficiency of whirlybird vents. While the turbine vents are compatible with most roofs, they may function less efficiently with some models. Sarking under the roof is crucial for the turbines to work.

If your attic space is open, the whirlybird will not be forced to suck out warm air through the vents. This results in reduced cross ventilation that then leads to ineffectiveness and uselessness of the turbine vents. A closed attic place to force air into the vents is therefore significant.
