Disappointment is Drippy

I'm a little disappointed with the results of the roof coating I did. At the joint between the two part of the cabin where I coated the roof, I still have massive dripping going on. I suspect it is coming in higher on the roof and running down the under side of the steep attic ceiling and then comes out where the angle of the roof changes. This would mean I would need to do something to the North half of the roof of the main cabin even though I won't actually be living under it. Now that the 8 feet or so of snow we got here this winter is gone, I might be able to find the problem.
