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?

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.

How are they different? Are they porous or spaced in a way that allows
air flow? Just curious.

The vents are sheet metal that is formed, textured, and painted to match the
concrete tiles. For the most part they do blend in with the tiles, and would
be easy to miss if you didn't know what they were.

On some other houses I see a few "metal tiles" shaped and painted to
look like concrete tiles from a distance. They are usually low on the roof.
I saw one yesterday from the ground but only 10 feet from the house.
I could not see any vents under the eaves, which by the way were very
short.

Plus the roofing tiles are not tight fitting so there's lots of leakage. It
may not seem like a lot of ventilation area but it adds up.
