My attic gets very hot, even with 3 turbines. Although it is very hot
outside (temp about 99-102), an AC service man recently said that my
attic
is still hot considering that all 3 turbines are working properly.

The house is mostly brick and I have vinyl siding over the wood
(veneer?).

No, veneer is wood glued to wood. Most furniture is made of veneered
wood, or for short, veneer. They use pretty, probably expensive wood,
and glue it to cheaper, less pretty wood. I guess even particle board
can be covered by veneer,

And I supppose some might call particle covered by Formica, or
something else that isn't wood, veneer, but I hope not.

Most brick construction around here is called "brick veneer" -- a
non-structural facing of brick over convential wood framing.

One can have veneer crowns of porcelain placed over one's teeth.

One may even have a veneer of attitude about one's person -- "a veneer of
self-confidence," for example.

Point noted. Thanks to you and Johnny.

I have now seen a second house roofed with a ridge vent for ventilation --
and no soffit vents. A neighbor's roof was done that way, and now a friend
is buying a townhouse that was recently reroofed (the whole complex was
reroofed), and the ridge vent is visible, but there's virtually no roof
overhang, no place to put a soffit vent, so they didn't bother. Parts of
the unit with an attic has what I'd call gable vents if they were in gables,
but I've warned the friend that I expect the '70s style cathedral ceiling in
the living room is going to get very hot, and his new neighbors have
confirmed that.

Didn't someone suggest putting vents on the roof itself, at the bottom
of the roof?

I can almost imagine that a ridge vent alone would allow hot air to
escape from one end of the ridge, while outdoor air which is colder
and heavier fell into the house though another end, or part, of the
ridge vent, but people seem to say that doesn't happen or happens very
little.

I can also imagine the hot air sitting inside the roof and barely
getting out because of the colder air on top of it that holds it
dowsn. Individual molecules would escape, but that would be maybe 1%
of what would leave if there were a fan to blow the air out, or even
good circulation.
