Water will "wick" due to capillary action into places you wouldn't believe. So will a driving rain and/or freezing action. The closed hangar will also emit moisture due to internal heaters and respiration. That moisture can enter seams and freeze, causing damage to seams, as well as corrosion/rust.
My hangar (built of flange-beam/R-panel) has putty-adhesive tape between each overlapping sheet of panel on the roof, because the mfr's all recommended it. It came in rolls and is similar to what is commonly used to seal mobile home and RV roofs.

Re: Quonset Hut hanger
Well!!
What a week!
As a previous contributor stated the arches are to big and flimsy-- like trying to stand up a 50' strand of cooked spaghetti--
We tried the scaffold style suggested by the manufacturer-- forget it.
After less than a half an hour a week ago yesterday I stopped the crew and said it is too dangerous and I would go to the local equipment rental to see what they had to offer.
Turns out luck was on my side.
A Sky Jack was available and delivery was to quickly follow.
With the delivery we disassembled the 1st arch into halves and and set them on the Sky Jack and started to raise slowly until we could marry them up again.
It worked but really wobbly and lots of ropes to tie off.
Once the second arch was up it provided quite a bit more stability-- not unlike another 2 construction items do when put together--that some readers might recognize!
On it went with each new arch assembled adding to my comfort level.
About half way along we switched assembly style by assembling 2 long section panels on one side then 2 long and a short on the other side and using the Jack to lift each up while 3 guys on the ground guided the base into the trough-- bolting together --then heading over to the other side repeating the process.
This left us with only 3 single panels to bolt on top to complete the arch.
We found that it was much safer but obviously a bit slower than a complete/ half arch lift at one time.
Friday afternoon the final crown section of the last arch was installed--no injuries, incidents or damaged panels!
What a relief.
Everyday I would head over wondering if it was still standing!
I guess it will take awhile for the feeling to go away.
My crew/ friends worked all day , everyday -- even when I had to escape to do my school bus runs.
I am hoping to put together a "hanger party/ BBQ for them to show my appreciation.
I do have some pics and will try to get them up.
Again, thanks fro all the tips and input.
