Since it's closed, the ony cure is to hire somebody to redo it for you.
So it sounds like builders sometimes show the flash valley, and sometimes do not. In the neighborhood I live, I looked at a few homes and noticed that it doesn't show. The house behind me is another builder, and it doesn't show.
I would assume that its a trend is to hide the flash in the valley since it might not look as nice if it shows. But this causes water problems for the roof, and after 10 or 15 years, the paper under the roof will start to wear out due to excess water flowing outside the flash area, due to debris. This happened to several homes in the neighborhood.
So one solution is to clean the flash in the valley every few years or so.
