All things being equal wind driven turbine vents also known as a whirlybird roof vent do move more air than flat vents but only when the wind blows.
Roof wind turbines pros and cons.
Residential wind turbines yields energy savings and protects homeowners from power outages.
What are the cons of wind turbines.
Wind power can be less consistent and less predictable compared to other types of alternative energy sources.
Roof vents need to move hot humid air from the attic to the outdoors so that humidity doesn t build up and cause mold rot or other moisture problems that findlay roofing regularly sees when dealing with attic issues.
A ridge vent is a passive system and offers less air movement and in moderate climates this style tends to be sufficient.
Must have prepper tools.
Cons these are most effective when they are used in combination with a continuous ridge vent.
These fans are typically installed along or close to the roof s peak which is called a ridge.
Since turbines are attached directly to attic spaces they can siphon away that moist air effectively.
How much air must be moved.
As good as they are there some traits that may make an alternative vent more suitable so let s look at those cons next.
Wind turbines aren t particularly attractive to look at however they are becoming more and more aesthetically pleasing with minimum visual impact on their surroundings.
Pros these types of vents are able to provide air intake for your roof s ventilation system.
Due to their moving vanes turbines provide more air movement than ridge vents.
Cons unfortunately there are two sides to every coin and turbine roof vents are no different.
List of cons of wind turbines.
A residential rooftop offers neither.
Wind turbines do emit a low frequency noise.
The benefits of using a turbine.
Wind speed increases with altitude and the top of a house is pretty close to ground level.
However if you re in an area without a great deal of wind a turbine may not work well.
Even worse all the obstacles trees other buildings even the house itself cause turbulence in the wind.
Turbine fans use only the wind blowing outside in order to rotate.
Wind driven turbine vent wind driven roof vents will pull more air from the attic but only when the wind is blowing.
They might not be cost competitive.
To make wind power cost effective turbines need access to strong and sustained winds.
