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.
