I was wondering about that junction but being as you had it all tidied up I was hoping for the best. Naturally, after the fact, us armchair quarterbacks can make all kinds of recommendations.
Normally it's better to have all the roofing panels running in the same direction and over lapped. But, where they're running at angles to each other a "valley" or "ridge" of sorts is required. In other situations where a metal roofs butts up against a wall then "flashing" is required.
Where is it leaking at? The lower portion (large gap) or upper portion (small gap)?
Are the coop rafters/headers at the junction area screwed in or nailed? You might could unfasten them and use some wood blocks to elevate the near rafter to bring the coop roof inline with the run roof. This would leave a smaller gap/area to deal with and would create more slope away from the junction. They also make foam strips to insert between pieces of roofing metal to "seal" against water leaks...those could be used in a reduced gap area. Otherwise, some creative bending of some metal flashing and lots of roofing tar/caulk/etc may seal up the existing area in it's current state.
As for as raising the roof....you could probably simply unscrew the tin, slide some blocks/2-bys beneath the tin and see how it looks. Maybe slip some of those foam strips in there while you're at it. If you get the new wood situated nicely and the metal roofing where you want it then you could use some hurricane strips or something to secure it to the main structure...you only need to really secure it for wind protection as there isn't much of a weight load there. A small gap where the roofs meet will be much easier to deal with than a varying, wider gap. For "overkill" you could pile on some roofing tar at the gap and cover that with a strip of flashing material.
I can't remember...were you going to incorporate a gutter system for saving rainwater?
Best wishes and thanks for posting all of this...I'm sure it helps others being as lots of people are building coops as their first attempt at building any type of structure. Keep up the good work and keep the progress and photos coming!!!!
Yes, we just got soaked with 3.5 inches of rain since yesterday with up to 4 more inches by in the morning...and it's headed your way Not exactly Noah's flood but definitely would tell on a leaky roof! It's WET down here!!!
Best wishes!

it seems to be leaking in the large gap area. BUT my wife went in this morning (because I had to work and she didn't) and said it looks to be dry after putting the window flashing on. I'm going to silicone a few area I'm afraid may get bad if wind and rain come from the eastward direction. I knew going into the coop roof that it was going to be of a challenge to go a different direction but I felt like it "looked" better that way and just went with it.
I'm going see after the next three day downpour if it holds, if not then I may end up doing what you said and raising it to match the pitch of the other roof.
I really do appreciate you Ed! you have been a big help during this whole build and I just wanted you to know you have kept me positive!
as far as helping other, I do hope that this thread will help those in similar situations and I hope that in the future I can also give good feed back like yourself!
