Ridge Vents or Wind Turbines
Posted on 3/19/21 at 8:51 am

I amn having a roof replaced and currently have the ridge vents. There seems to be plenty of ridge the way the house is constructed.
But wondering if I should just go with turbines.
Thoughts?

literally just researched the crap out of this as i got a new roof a couple of weeks ago. You either only want one or the other unless you only have a small amount of ridge, as they work against each other. however, the ridge vents only work if you have proper air flow through your soffit. I ultimately just stayed with ridge vents. i didnt want the hassle of having to cover the turbines in case of another week of freezing weather.

The main issue I have with turbines is they do eventually fail. Bearings will fail and you will eventually have to replace the turbine.
I had to do that just last spring when it became apparent the bearings in one of my 3 turbines were going bad with all the squealing I could hear when it was turning.

Very loaded question with no definitive answer. Biggest thing as mentioned above is airflow from the soffits. If you don't have enough soffit vents, doesn't matter what you use up top.
Builder friend who studied this extensively swears by turbines. As long as they are installed properly, which is within 1.5' of the ridge of the roof. A lot of them are installed too low because the homeowner doesn't want to see the top of them from the front of the house. I've built 5 of my own houses and have used turbines every time.

One benefit to ridge vents....you don't have to worry about them coming off in a big wind like a hurricane and you get left with a 10" hole in your roof.
I guess they could come off...I just have never seen them come off like turbines are more popular/easy doing so.

Turbines do a much better job of moving hot air out of the attic. They are better in every way except for aesthetics

What about electric fans to remove hot or cold air from the attic?

From my research and experience do not do the electric fans, the bearings in the motor go our consistently and the are energy hogs in the summertime because they are constantly running. If you did not have ridge vents then I would put in the turbines. At my previous house I owned it had one electric attic fan and I had to replace it 4 times in nine years before the last time I just said screw it and disconnected the wires and capped them off in the box. I changed it when we sold the house as it came up on the inspection report as the only thing that needed to be fixed. They are a bitch to change and they are typically going to go out in the hottest part of the summer. They do nothing to remove cold air as mine was on a thermostat and the lowest it would go was 90 degrees so doubtful it would work in the winter.

If this is the case then stick with ridge vents, otherwise turbines might be a better option. As others indicate make sure that the area of the intake soffits at least equals the area of the exhaust ridge vents.
Here is a calculator LINK to determine if you currently have sufficient ridge vent and soffit area to properly ventilate the attic.

High quality turbines, all day, everyday.

Negatory. They last about 3-5 years. At least in my experience.

Replaced roof last year. Had limited ridge vents due to steep angle/design of the roof. Added two whirlybirds and the difference in attic temperature is noticeably lower now.

Exact same scenario as me.
Adding the whirlybirds dropped my attic temperature significantly.

Now go back and wrap your attic in radiant barrier to get it another 10 degrees lower.

I'll pass. Acadian style and from attic floor to top is a good twenty feet.

Only issue I have had with a roof is boots rotting and the ridgevent coming off in an afternoon storm.

Ridge vents work fine in my gable end house—-so it has a really long straight ridge line for venting over most of the house. No mechanical parts to replace. It did leak a tiny bit during the last hurricane, but wind was blowing ridiculously hard, and neighbor lost his power vent, so....
Ridge vent plus radiant barrier

So I have ridge vents with a lot of soffit vents. I also have vents in the side walls that are still open. Do I need to seal them to force the flow up through the soffits?

Snow blows in ridge vents around here so I'm going with turbines.

My attic is sealed off and fully insulated. No ventilation and it doesn’t get hotter than 80 degrees.
