Metal corrugated roof! Ugh...

[aart]

@aart . I just re-read it again after having been reading on it for weeks.

OP is having a hard enough time, doesn't need to be deluged with repetitions.

Ventilating should fix your condensation problems. Google why a glass of cold soda or tea sweats and it will explain how condensation works. No amount of coating or insulation will make it better, actually any insulation will make it worse. Anytime the air humidity is high and the temperature balance between inside and outside is out of balance, condensation will occur on one side or the other. Evenings when the coop is warm and outside is cooling, condensation on the inside. Mornings when the coop is coolest and sun heats the air, condensation will form on the outside of the coop.
There is a science to this but it doesn't take a rocket scientist to make it work. Just Google a "Wood's chicken coop". It's closed on 3 sides windward, and completely open on one wall, the chickens don't freeze and there's no condensation problems. Down south here, I use a modified Wood's design. It's closed on the north side and open on the 3 other sides. But the temps here seldom get in the single digits, just the teens. And have yet to have a bird die over night from freezing. You've been given some good advise on this thread, but you've also been coddled into to doing some worthless bandaid repairs.
Even with the near flat roof, if you open up a good bit more ventilation your condensation problem should be fixed.
Just remember,
even Martha Stewart can't make chicken salad
out of chicken poo.

Thanks.

Yeah haven't had an issue yet (knock on wood) but I'm not going to take a chance! I'm kind of upset with the guy who built it, he owns chickens and makes coops as a side job. I had to insist on adding windows, he insisted I didn't need any ventilation either!!!

Hmmmm...I would be very upset. Have you ever seen his set-up?

Unfortunately the way I had him set my coop (which way it faces) I cannot put the vents on the tallest wall. Our first snow we got, the snow stuck exactly where I would of had the vents. My main entrance faces the west, I didn't think placement through to well.

YES YOU CAN! I haven’t read the whole thread, 103 messages to go, but I think I have the answer.
BAFFLES!
Ok for some reason I can’t get my phone to copy the link to my article about baffles. Just search it “Ventilation got you baffled?”. I had a desperate situation needing ventilation immediately. Baffles to the rescue! Put them at the highest point of your highest wall. Cut several long rectangular vents at least 4 or 6 inches high and at least a foot or 18 inches along the entire top edge of the wall. Cover with hardware cloth. Add baffles. Done. What do you think @aart? Wouldn’t this work here?

Yes, and you can buy baffled vents at the big box stores too, and add hardware cloth on the inside.

Before the snow and cold start up again I'm in some much needed help/advice.
This past summer I had a nice 10x8 coop built. It currently has two smallish windows on either side of the main door to enter the coop. I have it decided off so my 9 bigger girls and 3 ducks are one one side and silkies are on the other side. There are two chicken doors. The back half of the coop has a covered run and the one side has a covered run.
Now to my issue... The darn roof inside the coop constantly has moisture!!!!!! As we all know excessive moisture in the coop is not good, at all. I have tried spray foaming areas that were adding to the problem, added extra ventilation, opened the coop windows during nice days! Nothing helps. I recently bought a couple cans of flex seal to spray the seams, but my brother says that because it's a metal roof it's not going to help.
I am tempted to spray flex seal on the whole inside of the roof then put up that foam insulation.
Does anyone else have a metal roof coop that can advise me what to do before the snow and frost hit again? The roof is literally dripping all over inside!! Thanks for any suggestions.
I will add pictures tomorrow.

I think you have vent issue. If it is me, I would add windows with rabbit mesh screen inside and allow to open the window for air flow in/out. The window would not be directly from the windy side, but but the side that provide little wind.

Looks like roof is not pitched? Take off metal, add plywood, then 15lb felt and reinstall metal roof.

I'm rather late to the party, apologises.
I had this problem with my metal roof as well. My father had to put plywood underneath, and plenty of ventilation holes with wire mesh over them, and that fixed the problem!

The problem is there is moisture in the coop. Chicks expel a lot of moisture. Ventilation is one way to reduce or resolve this problem. Check out Woods open air design coops, lots to learn. Just because you stop the cold metal roof from condensating doesn't stop the concern, moisture in the coop. By sealing up the coop more, you are actually causing less ventilation and keeping more moisture in the coop. If your chicks are fairly cold hardy, dry and cold is far superior to moist and . . . .
Ventilation is great, drafts are not. Good Luck. Chick Rick.

That looks nice... but I understand that in cold weather that's exactly what's gonna happen... even here in the Philippines metal roofing is an issue. it needs to be installed with an insulator. for the heat.. but not for cold since it's going to moist out.
