The other option is to add passive roof turbines. They were popular in the part of Alabama we lived it. I think they are ugly so when a tornado damaged our roof we replaced ours with ridge vents.

Roof turbines are not highly regarded by the experts as far as I know.

Any particular reason why? They worked fine on my house and are dead simple. Of course some things that work well in one climate don't work in others.

Here in hurricane country you need to remove and cap or cover and secure them. Depending on how long you wait you may be climbing around on a wet roof in the rain and wind.

I just set a circular saw to a depth that cut through shingles and plywood, then ran it across the roof on both sides just below the peak. Nailed the ridge vent over the opening. Cracked a brew.

You're starting to sell me on this idea.

Yep, that's pretty much what's in the video I linked above (well, except that particular product is a shingle-over).

These are quite widespread in my country. Not only wind makes it work, their speed is also affected by the air temperature at the room where it's attached to. However, since its speed may slow down when the moisture in the air is high, I wouldn't hold my breath for it to work so well for the purpose of getting rid of moisture.
