One of the most common questions posed in regards to turbine roof vents is why they are effective at all. I deal with this every day. People don’t understand how or why having turbine roof vents can work or be an asset. They see that there’s a bunch of holes on the roof, which means the heat will escape even more right? Wrong. Let me explain further.
Turbine venting is one way to cool your home without using electricity. Still, the primary function is much more efficient than simply exhausting hot air from your attic- it can keep your home cool in ways you might never have considered before! To help you better understand how these ventilation systems work, here are the pros and cons.
THE PROS: WHY YOU SHOULD USE TURBINE ROOF VENTS
There are plenty of reasons why you should consider adding turbine roof vents to your home. First, they’re easy to install. It’s usually as simple as cutting a hole into the roof during a reroof and installing the new vent. With that being said it’s also a bit cheaper compared to some of the more luxury items such as ridge vent.
Another reason why turbine fans are great is how long they last compared to other types. It’s not uncommon for them to last 25 years or more, which means you only have to buy them once if you get the right kind. They can be used in all types of climates, including snowy ones where it might be too cold for regular vents to work correctly. This is because they use small rubber seals around the blades and a metal guard that protects against ice damage. If your home tends to get hot during summers when you’re using your air conditioning, then these are also better than standard fans because they move just as much air without using up as much energy to do so.
Turbine roof vents work by drawing hot air off your attic floor and exhausting it through a series of small openings at the top of the turbine. We all know that heat rises, so when we can draw up this hot air from underneath your house and push it outside, we’re actually relieving some of the strain on your home’s HVAC system. Nothing will cut down utility costs more than freeing up room within your existing HVAC system!
With a metal fan pushing air around them, these fixtures are more likely to weather high winds without being damaged or destroyed.
THE CONS: WHY YOU SHOULD NOT USE TURBINE ROOF VENTS
By their very nature, turbines are not meant to be wholly wind-tight or weather-proof. Because they ventilate through such a large number of slits in the fins, they are more susceptible to becoming clogged by large debris or wind-blown rain. Of course, turbine roof vents aren’t the only way that you can enhance your home’s ventilation system! There are other methods, but turbine roof vents have become very popular among homeowners for all the reasons listed above.
This next con isn’t really a con, but more of a personal preference. Turbines are just unsightly. They protrude from the roof nearly 1.5 feet. A lot of other ventilation is lower profile and blends into the roof.
My last con is that there are moving parts that are exposed to the elements. With that being said as long as you don’t get a hail storm or something else damaging the vent there should be no issue with it. Say it does become damaged though you may end up hearing it squeaking or rubbing on the outer lip of the vent and will need to replace it with a straight vent.
As with any ventilation system, there are disadvantages and advantages based on where you live. If you would like to know more about how these systems can benefit you, feel free to drop me a line! I’d be happy to help where I can.
OTHER TYPES OF VENTILATION THAT WOULD BE GOOD IN PLACE OF TURBINE ROOF VENTS.
Increasingly, more and more homeowners are thinking of changing out their old home’s ventilation for a brand new one. This is due to the fact that used homes are prone to be less comfortable compared with the newer ones; this is because they lack many things that can make them enjoyable places to live in. For instance, used homes usually have windows that leak air from inside, making them cold during the winter season. In addition to that, it also prevents fresh air from entering the home, resulting in a stuffy atmosphere.
One type of venting system that is gaining popularity these days is the “powered fan,” consisting of many small ventilating panels positioned just below the roof’s shingles. With this system, you would only have to open or close the slats depending on whether you need fresh air inside your home or not. It works with a thermostat, so it won’t let outside air get in when you don’t want it to.
Another ventilation system for homes is driven by solar energy, and it only requires minimal installation as compared to other methods since they use fewer components. The exhaust fan can be installed at any place with sunshine, and it has enough free space. The solar energy is collected by a panel and passed on to the fan, where it’s used to power the exhaust fan.
In addition to those mentioned, you can also find several other types of venting systems explicitly designed for homes. Most of which are just passive vents such as box vents and ridge vents. Just remember that it is very important to choose something that will make your home more comfortable and energy-efficient. It’s a good idea to consult with a professional when going through the process of selecting a particular type of ventilation system because they can give you much better advice compared with what you might search on the Internet for hours and still not learn anything new.

Conclusion
Turbine vents are pretty good at what they do. They are a solid selection when it comes to getting adequate ventilation at a good price. The only real downfall other than what we pointed out above is the look of the ventilation. It protrudes out of the roof and has moving parts that can make noise.

I live in the Stonebridge Ranch community of McKinney. The home has three pancake type attic vents on the roof (original to the house, ie, over 20 years ago). Would turbines (no fan) improve attic heat reduction? I am ok with the physical appearance. Approx cost??
Well I can not tell you exactly. I would need to know the size of your roof and where they are at.
We have a long house and I asked one roofer about having two turbine vents, I already had one and it works great cooling the attic. The roofer told me two turbines would negate each other. Is this correct?
The claim that two turbine vents would negate each other is not entirely accurate. The effectiveness of multiple turbine vents in cooling an attic depends on their proper placement, the size and design of the attic, and the overall ventilation system. While closely spaced vents might interfere with each other’s airflow, properly spaced multiple vents can enhance attic cooling. It’s important to maintain a balance between intake and exhaust vents and consider factors like attic size and local climate. Consulting with a roofing professional is recommended to determine the best ventilation strategy for your specific situation.
