At the railroad museum where I volunteer, some of our pole buildings (with steel siding and roofs) are getting old and they are starting to leak.
These buildings are BIG!!! The largest of them is about 60 feet wide (four tracks wide), 800 feet long (yes, eight hundred), with 18-foot doors at the end.
I have seen a lot of advertisements for liquid-based coatings that are supposed to be good on these buildings. Has anybody had any experience with these things?

John,
I have used sta-kool elastomeric with great results to patch large commercial roofs. One had holes in it from an earlier silicone patch and was almost flat. It has held for about five years.
If you don't have holes the screws may just need replacing. Overcup screws tend to leak and those were used many years ago. Can you post a pic or two?
Here is site http://sta-kool.com/.

*Hey John - Where's the museum at ? Sounds like something that would be neat to see...........
*The barn is designed to hold this whole train:http://www.irm.org/pictures/600/2000dsldys09.jpgThis Nebraska Zephyr is the second generation diesel streamliners, built in the later '30s.And here is a picture showing our barn 9, the big one. It is intended to hold the whole Nebraska Zephyr.http://www.irm.org/pictures/600/760milw07.jpg
*I agree with your comments completely. And, many of these barns were held with those rubber-grommeted nails, which also loosen. Compounding the problem, the installers missed the wood far too often.But, applying new fasteners on a building that big is as costly as putting a new roof on. So, other alternatives are desired.These are typical pole buildings. Pressure-treated wood posts put into the ground, and backfilled with dry concrete/dirt mixture. Some have survived 15 years, but we are now starting to worry about the oldest buildings.
*It would not cost as much or nearly as much as a new roof. Find a good outfit in your area and ask about it. I would send two men for a week or two and they would get it done . You are looking at 4000 or 120,000 big differance there.
