dying dormer valley in the middle of the sheet

I am putting delta rib metal on a 12/12 roof. There are two dormers that have a dying valley. When I cut in the valley there is exposure below the valley cut and the remaining sheet under the dormer eaves. What is the most efficient method of flashing and sealing the sheet cut that intersects the "w" valley flashing

You should of course be contacting the manufacturer and getting their instructions. I am not familiar with the term dying valley however I assume it is where the valley terminates onto the roof. Generally speaking you make sure that the fascia on the dormer does not rest on the main roof. The sheet metal for the main roof needs to be in two lengths and it is always best to lay the roof sheets out centred on the dormer so that you end up with as near a full sheet on each side of the dormer. Then install the lower sheet on the main roof by sliding it up under the dormer fascia as far as possible. Then install the valley metal over the lower sheet, formining it to fit as tight as possible and bedding the termination in butyl sealant. Then fit the upper sheet overlapping the bottom sheet and cutting it to the valley.

I am typically addamantly against splicing any sheeting. I was especially against any splice on this roof; as it is a$900,000 log home with decks that give view back up to the roof because of their expansiveness. I managed to resolve the issues I had by extensive and exhaustive layout and precision cutting and fitting; as well as one invisible caulk joint with clear Lexall 100% silicon sealant. I wish to express my gratitude for your consideration and response. Thank you
