Kristi trailers is near me. Here is a link to a section on their roofs. They use corrugated galvanized steel, I think.

I am not a fan of screws on the roof, this goes for my older mobile home too.
I just installed a one piece aluminum roof on my home made 16' x 57" wide trailer. I rounded the edges, rolled it over the sides and screwed two alternating rows of metal roofing screws. Have to remember to post a pic...
The seams on the roof may be better than screws and/or massive amounts of dicor sealant.
