Replace a wind blown off roof.

[Nancy]

We had a microburst about a month ago and need to replace the roof on a 1978 Atlantic. Apparently the walls will not take a truss roof (per contractors who do not want to work on it) and Butch, (BG's Mobile Home service), here said a split-truss roof (??) Either way, we are on our own and need some advice. The arches are left on, but the metal actually separated and blew off to one side. There is an addition connected to this that also needs a roof, but that can be a later project. They are setup like the letter T, We have access to shingles and lumbar, metal if need be, we live in Montana and have to deal with snow in the winter and sun in the summer. Any suggestions will help. Thanks.
