    Default Valley weave

    Does this weave look right? To me, it looks like the roofer only weaved every other shingle. Yes, I was there and I took the picture but I had to come back and research it.
    My other concern; it's a fairly low slope roof. Any comments are appreciated.

    Kind of a small area, but it looks to me like it is wrong. The keyways should not be at right angles to the flow of the water and it looks like they are.

    It's probably right. When you weave a valley where there are two different pitches involved, corrections have to be made by double coursing to keep the parting line running in the center of the valley.
