Wind Turbine Roof Ventilators

Chances are, you’ve seen them a time or two: those round knobs poking out of residential rooftops. Well they are WhirlyBird Wind Turbine Roof Ventilators.

Those are wind turbine roof ventilators, and apart from being eye-catching, they’re also an incredible investment for your home.

Today, we’re breaking down why roof ventilation is essential. We’ll also cover how roof ventilators, also called Whirlybirds, can make a world of difference.

Why Roof Ventilation Matters

Year-round rooftop ventilation is critical if you want to keep your home comfortable during the Western Cape’s hot, balmy summers and insulated during the cold, wet winters.

While there are several different kinds of roof ventilator systems, Whirlybird turbines vents are ideal for South African homeowners. Powered by the breeze, these vents contain a small circular fan inside that helps draw up and disperse your attic air.

Let’s review a few reasons why this system is a must-have.

Attic Ventilation

Step into your attic on a sweltering summer day, and you’ll notice that the temperature soars upward more than a few degrees. This is because our attics hold in the hot and humid air.

If allowed to build up, that air can lead to excess moisture, rot, and dangerous mold. As wind turbine ventilators attach directly to your attic space, they’re perfect for siphoning this air up and away from your house.

Think you don’t need the same ventilation in winter months? Think again.

When it’s cold out, those same ventilators help disperse the warm air that rises within your home. They also remove cold, moist air, which can cause the same health issues as hot, damp air.

Heat Management

You don’t want to spend your summer arguing over the indoor temperature. It needs to be comfortable, and WhirlyBird roof ventilators can get you there.

If you have the right number of vents installed, they will work to extract heat from your roof cavity space, reducing the heat in that area. At the same time, they keep air moving in your home and enable natural evaporation, moving excess heat out of your house.

All of that extra heat can wreak havoc on the exterior of your home, too. When the sun beats down on your roof during the summer, it can reach temperatures that exceed 75 degrees Celsius. This can wear away the plastic underlay or the Sisalation foil fitted under your roof, making it more susceptible to leaks.

Roof Condensation

Have you started noticing condensation on your windows? What about your walls? This is a sign that your home’s moisture levels are too high.

If you’re able to keep those levels down, you can improve the structural integrity of your home over time. Installing WhirlyBird ventilators on your roof keeps the air moving and helps regulate moisture levels.

Allergy Management

If you allow the humidity levels in your home to inch higher and higher, it can trigger or exacerbate allergies in your family members. This is important, as up to 30% of South Africans suffer from seasonal allergies.

Proper roof ventilation removes stale air and improves the air quality inside your home. It also siphons out air that contains the following contaminants:

  • Cleaning chemicals
  • Dust
  • Mites
  • Cooking fumes
  • Pollen
  • Lead poison from car exhaust emissions

Ventilation allows fresh air to enter your home and removes old, stale air. An added bonus? When you take care of this step, you also help make the indoor air smell better, too!

Ridge Vent Alternative

You’ll notice that some homeowners rely on ridge vents for ventilation instead of turbines. Rather than attaching to your home’s attic space, these vents sit along the ridges below your roof.

While these work well to vent hot attic air, some homes do not have the room to allow for them. If your attic space requires ventilation, but you can’t install ridge vents, Whirlybird roof ventilators are an ideal alternative. You can be flexible in their placement, and most homes always have enough surface area for them.

Note that a balanced ventilation system includes both ridge vents (or other exhaust vents) in addition to intake vents installed at your roof’s eave, soffit or fascia area.

No Energy Source Needed

Wind turbine vents are passive vents and don’t require power to run. Instead, all they need is a little wind, which is usually always present on your roof, even on the calmest days.

The result? They move a ton of air for zero electric cost. After you invest in their initial installation, you’ll reap the return for years to come.

Over time, you’ll find that Whirlybird ventilators, in particular, can save you money on your utility bill by helping your home use less energy. When your air conditioner isn’t pumping at full blast to move that hot air out of your attic, you’ll notice the savings.

Reliable Performance

These turbines feature a simple design with few parts. Moreover, they aren’t impacted by many environmental factors that could create wear and tear.

Apart from large debris, they’re protected and high-performing, requiring little maintenance over their lifetime.

WhirlyBird Roof Ventilation Benefits

  • Reduce roof space temperature on hot summer days.
  • Cooler home in summer
  • Remove moisture and condensation in the roof space.
  • Reduce condensation and mold in winter by recycling cold damp air
  • Wind Turbine Roof Ventilators will save plastic underlay or Sisalation foil from breaking up and disintegrating with a cooler roof space
  • Remove stale air from the roof
  • It helps reduce damaging moisture. Excessive moisture can build up in the attic, potentially damaging the structure and degrading the roof system. It can also lead to mold.
  • It can help save energy. Heat build-up in that attic comes at a cost—a home’s air conditioning has to work harder to cool down the house, especially the living space below the attic.
  • It helps prevent damage to the roof shingles. High attic heat can bake the shingle and cause them to prematurely age. In fact, most major shingle manufacturers strongly recommend proper attic ventilation on asphalt shingle installations.

WhirlyBird Roof Ventilators Remove Stale Air and Heat Fromm The Roof Space

Roof Ventilators Remove Heat as Well as Stale Air From The Roof Space. Improving The Indoor Temperature In The Roof Space

Importance of Removing Stale Air In The Roof Space

Removing stale air from the roof is excellent from a health point of view. However, there are many other important factors that we need to also take into account. Additionally cold moist air in winter allows cold damp air into the roof space. As a result, removing the moist air is essential.

A key ingredient to creating mold or condensation in the roof is moist cold air. WhirlyBird Wind Turbine Roof Ventilators remove up to 5000m3h of cold air reducing the potential for moisture in the roof space as a result of the airflow in or out of the roof. Removing stale air is also healthier for the family and also reduces the smell of the stale damp air.

WhirlyBird Roof Ventilators Reduce Roof and Ceiling Damage

Sumner Benefits: In summer the heat build up in the roof space, and temperatures can exceed 75 degrees C.  As a result, the heat in the roof can damage the plastic underlay or the Sisalation foil fitted under the roof.

Many homes have perished, or damages foil under the roof. As a result, homeowners will be exposed to the potential for roof leaks in the rainy season. For this reason WhiryBird Roof Ventilators will reduce the temperature in the roof space by as much as 30 degrees.

As a result, improving the internal temperature in the home.

Winter Benefits: The facts are in the Western Cape we have long cold wet winters. Therefore the cold, moist air that is in the roof space needs to be circulated and removed.

Damage from the moisture can affect the wooden trusses and batons. Additionally, the ceiling will retain some of the moisture creating a damp cold ceiling. Therefore any Roof Insulation in the Roof space is also affected by the moisture.

Fortunately, most Roof Insulation materials will dry out on the first hot day. The potential for mold and condensation in the home increases substantially.

Importance Of Whirlybird Roof Ventilators

Realistically WhirlyBird Roof Ventilators should be fitted on all roofs that do not have proper roof ventilation. In fact, most homes in South Africa do not have the right roof ventilation benefits.

Most homeowners are of the opinion that Whirlybirds are only for summer use. This is not the case as cold winters create harmful moisture build up in the roof. The Wind Turbine Roof Ventilators remove the moist air and circulate with fresh air continuously.

Also, all new homes in South Africa must be insulated with the correct Roof Insulation for the specific province. As a result, cold, wet winters can affect the insulation by leaving moisture in the Ceiling Insulation. Well ventilated homes will not have this problem. Additionally the potential for condensation and mould is reduced substantially.
