But the ridge vent maintenance and running cost is a lot less than for turbines when.
Pros and cons of to roof fans ridge vent.
You ll be able to move air throughout the attic without the use of fans or turbines when enough space is given to this vent design.
Because it has no moving parts it is unlikely to break.
So you have to put more money into ventilation systems than others.
The effect of ridge vents for the roof depends upon the energy efficient nature of the structure.
Cons these are most effective when they are used in combination with a continuous ridge vent.
A ridge vent runs along the entire ridgeline of the roof.
What are the cons.
If you were to install about 40 feet of roof ridge vent the area would span up to 10 turbines in this case 10 turbines would cost you substantially more to purchase and install.
However if you were only going to install 3 or 4 the turbines would be more affordable to you.
List of the cons of roof ridge vents.
Generally his is accomplished by either using ridge vent or by installing a soffit under the eaves and then exits near the peak of the roof through which the air can exit.
If you have good continuous soffit venting and a ridge vent then any type of attic fan may be totally unnecessary.
However in my experience most homes do not have the proper passive ventilation.
A properly installed roof ventilation system should be constructed in a wave that creates a constant flow of fresh air throughout the attic.
Ridge vents do not always provide the proper ventilation in some homes.
These types of vents contain motors that drive large fans.
