I have one of those fans that blows out the vent under the gable.
I think that's the right term.
You mean you have a fan like this:

Yup. It's unplugged and will probably stay that way.

Wouldn't it just pull right from the ridge vent directly
above it making it practically useless?
Yes - that's the problem someone could have if they have a lot of
passive roof venting near the fan. I don't have ridge vents on my house
(I don't have enough of a ridge line to make it worth while).

BTW: We had 42 days of +100 degrees last year. All time record.
Yea, that's a killer for shingles.

Not good. It's ply-board and the vents (about 6" x 12") are a
good 5' apart. Replacing some of the ply-board will be difficult.
So you don't already have aluminum-clad soffits then... ?

Looks like this w/o all the dirt
