That green piece and the valley should be done in one shot. That way you put your valley flashing on run shingles from green section long on to next roof then do other side of valley run long also then snap line from top to bottom cut and tar. Only nail on top edge of flashing roof cement the rest. My opinion

thanks Joey (i'll have to read that about 3 times before i get it)

this is how i intended to run it (in my first picture with the green, i should have made this more clear)

so like you said, in and across the valley

now, since i am reshingling the roof, going over existing shingles soo i was not planning on adding a new flashing, since it is allready under the existing shingles

(so first green, then orange)
