I am not to concerned about a hump since the rest of the decking is not perfectly flat. 7 in wide boards some are curled at the eds or bowed in the middle both up and down.
A house fe blocks short of me did stagger start in the valley but he use valley metal.
I know you start on the size with the smaller area if both slops are the same pitch.
However, what if the smaller area side stops about a foot or two short of the eave? Can it still be done or does it have to start on the other the other way around?
I would like all my valleys to match (have 4 valleys house shaped like a t). All facing each other or at least the back match each other and the front matches each other.
