This is a serious question, but what do the turban looking things on the top
of a house actually do? Do they let air into the attic, or keep the attic
cooler or what exactly?
(Yes, I'm seriously needing to know)

They allow hot air to rise out of the attic and keep it cooler.

This is Turtle.

Yes Roof air turbines are very good to have in warm or hot weather for they let
the hot air out the turbine from the attic area during hot weather. To your
question here. The let the hot air out of the attic and don't let it in. Cooler
air comes in the eves of the house in the attic area and then lets the hot air
rize and go out the turbine to cool the attic. Now during the winter or cold
weather they have very little use.

Now they are worth having if your weather temperature of the summer goes over
80ºF and your house is in the direct sun lite during the day.

Yes, have them replaced with the new roof your having put on and I suggest new
ones instead of leaving the old one on there. Did this help ?

Turtle,
Yes, it did help a lot. And please forgive me that I don't know the correct
terminology, but there are 'vents' on what I think is the eave. (Underside
of area that sticks out from roof). The holes on the vent are kind of big
(enough for a bug to get in) about big enough to fit your finger into. I'm
wondering if I need to cover them, or if they are necessary? Or should I put
some type of screen material inside them to keep bugs out? What do people
normally do? We don't have bugs in the attic that I know of.. maybe I'm just
a worry wart?
I appreciate any advice/help.
Thanks,
lucy

Don't block them up, they allow the air to move through the attic to the
turbines as Turtle disclosed. if you have bug issues you can put a screen
over them. I would do this from the attic side, it will look better. make
sure insulation is not impeding airflow too.

Oh! Not so!

Keeping the surface of the roof cold in winter is essential for
preventing accumulated snow from melting and forming ice dams at the
eaves.

Some may argue that the turbine form of roof vent is an overly
complicated solution to the problem, having moving parts and all, but
they sit higher above the roof surface than other sorts and keep
clear of the snow. We've had 'em on our roof for over 15 years with
no problems.

I'm in Texas. Snow.. what is that?
Some were covered with siding and there are two left. Is that okay, or what?

There's a formula for it, but I'd guess the rule of thumb is about 2
times as much soffit venting (that's what you are describing) to one
foot of turbin vent. Personally in an area that is mostly hot and mostly
snow free, and of course where financially feasible, I prefer a ridge
vent. No moving parts (that means no rattles or squeaks) and it easily
vents the whole attic (assuming you have enough soffit venting. Gives a
prettier roofline also.

Cute.

Well, I'm told that a properly ventilated roof and insulated attic are
just as important in warm climates as in cold.

I wouldn't know about that myself; it was about 45F here this morning.

Do cover the holes under the eves of the roof area with the proper covers bought
at any hardware store. They will cover the hole up to not let bugs get in and
will still let air flow through them. These covers call eve vent covers and run
about $.98 to $1.50 each. Replace all of them and let the attic venting system
work.

Yea, it got cold this morning and got down to 85ºF this morning in Louisiana.

Interesting discussion...

They work quite well (supposedly developed for ventilating chicken houses in
Rhode Island many years ago).

Winter or summer, they key is ventilation to prevent misture buildup that
causes big problems, long term.

I would let the units work year round.

For what it is worth...
