I am in a new home and I noticed that the shingles were placed across
a valley where two roof sides intersected. It seems to me that there
should be a strip of metal flashing down the length of the valley and
the shingles should be flat against each plane of the roof. The way
that it was done creates a curved shingles covering both planes and a
fair size opening at the eave. I wonder if there is one right way to
go about this...

What you're describing is what I believe is called a "closed valley". I
don't like the look of it most of the time, but if it's properly done, I'd
wait until the roof need replacing before I did anything about it.

in these parts, that is called a woven valley, and many people feel it
looks better than having flashing in the valley. using sheet metal in
the valley is no more waterproof than a woven valley. It's a matter
of preference. Just how new is your home? If the roof hasn't been
through a summer's heat, the shingles will lay down in the heat.

A woven shingled valley in my opinion is better. It is uninterrupted and
therefore no seems. It would be my preference if I had one. depending on
how large the opening is at the eave I'd say you have a better roof. Is the
opening more than say a 1/2 an inch? It should shrink after a summer's
worth of heat.
