My barn is a glorified carport with three openings in the front it is 24 by 36 and the highest part of the roof is 14 ft. It has a ridge vent along the top but when it rains and especially on days like this morning where it is freezing cold and then it warms up the building sweats I have tarps and then double layer of pallets and then awning material over my hay to keep the water off of it but I would love if the building would just not sweat at the top at all. Does anyone have any suggestions as far as foam insulation panels or something that I could put up in the summer on the ceiling to keep it from sweating or at least keeping the sweat drips from coming down into the barn that would not get moldy super fast?? I’m in East Tennessee so we get hot humid Summers and in the winter it freezes and night n then gets up to about 40 during the day.
My old barn would do the same, hated trying to keep my hay from getting wet due to it. When I had a new barn built we had them insulate the ceiling and no more walking into a barn that pretty much rains on you on the inside.
The old barn is now the shop area where we keep the tractors and mower, my son complains about the raining inside also, lol, so told him the only thing is to insulate the ceiling to stop it.
I did a quick google this morning and the company that built it was one of the first “insulation install ideas” to pop up. Im going to give them a call n see if they did it in the spring what it would run me 
When my pole barn was built I bought the rolls of insulation that is silver on one side and white on the other. It is like bubble wrap. My builder thought I was nuts! Works like a charm. You should be able to somehow tack it up yourself. In my case the builder put it on top of the rafters, then put the roof sheet metal down. It has been a few years so I do not recall where I ordered it from. And FYI, I am in NC - hot, humid and in winter lots of rain!.
I will check that out too!!! I dont have any wood to tack it too and my ceiling is clear span though. Maybe i can figure out a way to glue it lol. But then I wonder if the humidity would just unglue it 
Here most any more use spray-on close cell insulation.
Goes on fast, it insulates better than most other kinds and is not very expensive, because labor is much less.
Some don’t like that it turns yellow with time.
Painting over it makes it be whatever color you choose.
Our local garage sprayed that in all their shops and painted it white with a dark green accent and it looks very nice.
We have it in our metal well house and it stays dry and warm in there just fine.
It was white and did turn a light yellow.
Insulation will cure this dripping
We have the same problem and have used the aluminum / bubble insulation as already mentioned. It works well but unfortunately the edges / joins weren’t sealed with the right stuff so they drip from there.
This summer we’re stripping it down and doing closed cel foam on hubby’s insistence.
For those of you considering new roof panels, the panels can be ordered with sprayed on sound deadening/insulation. Obviously costs a bit more, but before being on the roof is much cheaper to insulate then applied roofing.
I talked to a couple insulation ppl n they said the same thing. Im either going to try to dyi with some kind of panels from lowes or home depot, or bite the bullet in the spring and get spray foam done.
Spray foam is amazing stuff. I’ve got it in my barn and house.
I know but my quote was about 1500
When my BO built her steel building almost 20 years ago the plan was to insulate the roof. She decided to do the walls also. The builder installed all of it. The only things that drip sometimes are the skylight frames. Depends on the weather. if there is enough condensation they will drip. It’s not an issue because there is plenty of distance between them. If they drip on you, you can move a couple of feet and stay dry.
The sparrows have made a mess of the roof insulation over the stalls. They pick at it and build their nests. Some sections are pretty messy, but it doesn’t bother anybody.
The building is 120 x 200, which is huge. A lot of insulation, but it was worth it.
What kind of insulation did she use?
I believe it is regular fiberglass. I don’t know how thick. It definitely has a plastic sheet, not paper or foil, which is white. I don’t know how they attached it. It has a stretched look, not wrinkled. The website is heartsnhorses.org. (not .com) I know there are some pictures of the interior if you poke around a bit. Not much on the Facebook page.
