Look closely at the concrete tiles, are they all the same or are a few of
them scattered here and there "different looking".
Those are the vents.
Your home inspector should have pointed them out to you.

I recently bought a newer home in Pinal County north of Tucson, Arizona.
As
I look at my home and at almost all the other homes in the development, it
appears that very few have any roof ventilatioin near the top/ridge/peak
of
the roof. Mine appears to have ventilation only only under the
eaves/soffets.
I've walked all along the roof, climbed up through the trap door into the
area
under the roof, and I can find no upper level ventilation. And the
roofing
material is concrete tiles. I've look closely, without removing any
tiles, and
cannot see any evidence that there is a vent all along the ridgelines as
there
is no extra gap under those ridge line tiles.

Yet as I drive around other developments on the north side of Tucson, in
Pima
County, most newer houses have some kind of upper level ventilation. Now
I'm
new to Arizona and warm climates. I come from the cold climate of
Seattle, where
very few houses had any air conditioning, and your furnace would be turned
on
from September 15th to June 1st. While the ceiling of my 2001 built house
is well
insulated, it just seems to me that not having any upper ventilation, the
roof is
trapping a lot of hot air which in turn would cause the house to be hotter
than
it should, and therefore making it more difficult to cool down.

Is there something wrong in my thinking?
