Metal corrugated roof! Ugh...

[Mybackyardpeepers]

I did a lot of research prior to putting the metal roofs on my coops. I watched a lot of YouTube videos.

Rain is not the cause of the condensation. It is the temperature difference inside and outside and the humidity that causes the water droplets to form.

I would also warn against putting any kind of wood, plywood, OSB, hardboard, under the metal unless you put a barrier between them. Something like roofing felt. If not, you’ll have a bigger mess on your hands in a very short time.

Yeah I'm sure it will start to rot in time.

Ice/water shield is a rubber membrane - usually with an self-adhesive backing that you put down along the edges of the roof before putting down the roof felt and shingles/metal roofing. Its purpose is to stop the moisture from soaking into the wood sheeting of the roof when ice dams form along the bottom edge of the roof. melted snow/rain will back up behind the ice dams and actually flow up between the shingles and get underneath them.

Thank you for explaining, will look into it when we tear the roof back off.

I haven't read all of the posts yet but some of my roofs are wood with roofing felt paper over the wood just like if you were going to put on a house. I live in Florida where it is humid most of the time. I realize I don't have to deal with the snow. I do have some coops that have just metal for the roofs. I don't have the condensation problem but the coops have good ventilation. My bother is a retired general contractor. I used 1x4 wood under the metal. He lives in Traverse City, Mich. and he said they use 2x4 wood under the metal.

Thanks. I figured a guy with construction knowledge that built coops and owned chickens would have common coop building sense. I should of knew when I saw that nothing he built had ventilation. Lesson learned!

Ventilation looks like the problem. I would setup a fan and heater, run them both until it is a lot drier in that coop. Then add some ventilation near the top where the wall hits the roof. If you get it dry enough then insulate the ceiling. Those ducks are wet as heck and the chick breathe out a lot of water also.

What is ice/water shield?

Edited to add what we actually used. Not even a hint of moisture on the inside plywood- if you're going to redo the roof anyway … may as well use something designed for a metal roof:

This is great, thanks for all the information!!!

While you are remodeling the coop, add a microwave oven, central air/heat, jacizzi tub, flat screen tv, and cable for the birds comfort and entertainment!

I believe that could possibly be in the budget!! No heat, heat is bad remember!

I'm glad you have a sense of humor. I don't want to offend anyone. I do like to joke
around. and ok, no heat, but the wide screen tv is a must!

Next year I'm tearing off the metal and putting plywood down then the metal. I'm not sure if putting anything over the metal will help as it is sweating inside the coop.

Be absolutely sure whether or not you need roofing paper between the plywood sheeting and the metal roof. Decades age I was a roofer for a while and I think that this is true. Also raising the metal off the wood/paper might provide needed moisture control.

I am only part way thru the msgs (page 2) so this may have been discussed ... from your pictures it appears that your roof is flat. Is so, it could help enormously if you elevated one end. Also some spacing for ventilation at the metal roof ends; maybe an on edge 2x4 with 2 or 3" thru holes (cover with screen).

Your coop guy didn't do you any favors.
