Haven't seen this before

This may be a common way to do a valley elsewhere but I’ve never seen it here. Any one else? They ran a course of shingles up the valley–made a nice straight line–and then ran the horizontal shingles over that. Is normal in other parts of the country? Not sure I like the idea.

Appears to be a version of what this site calls a “Long Island” valley

The visible straight line gives it away right Marcel.:smiley:
No cut is a woven valley. I think Robert V knows this he just did not see the line.
