I worked for a short time for a company that did backlit awnings and fascias for truck stops. Some of the fascia panels that were installed on the canopies over the pump islands were 90–100 feet long. Shipping them in a large tube was the only practical way. It was expensive (they were usually overnighted directly to the construction sites, so 1000 dollars was a typical freight charge).
But, assuming we could have folded them instead of rolled them, I don't think we would have, because sometimes these were shipped in below zero weather. I think there could easily have been a problem with the ink cracking on the eradicated faces, as well as a problem with the first-surface vinyl on the vinyled faces because of the cold weather. Some of the vinyled faces were full coverage backgrounds with reversed out graphics. We tried to always roll them up carefully, tightly and smoothly, and then wrap them in angel foam, before sliding them into the tubes for shipping. The tubes we used were the heavy-walled tubes that the Cooley fabric was shipped to us in.
We never actually folded anything, though, so I am just speculating that it might have caused a problem.
