Older mobile homes, floors are very easy. You cut out a section from the top, replace or brace any damaged joists, replace floor with plywood instead of the pressed sawdust that was originally there. I use pressure treated plywood in the bathroom, kitchen, and laundry.
It's all done from above, very easy.
Roofs are a bit more work. From inside the trailer, remove the wall paneling and the scrawny little bit of insulation from the ceiling.
Roof support will be a frame of 1x1 boards. Those can be jacked up and braced. For broken boards, use sistering to support. It is just about impossible to remove and replace the whole thing because of how trailers were constructed, but you can brace them up solid.
For the roof, from the outside, sheets of tin can be cut to cover holes and glued down with roofing cement. That patches leaks just fine.
if you have funds, you can have the entire roof covered with rubber roof. It's expensive but will make that roof last for decades. As far as I know, it has to be installed by someone trained to work with it.
I've fixed two broken roof supports when a tree fell on a trailer. Roof supports fixed and holes mended for about $100 of material and 6 hours of hired labor. It's not a big deal.
By the way, a contractor quoted $30,000 to do that repair for me.
One thing about those old trailers, is that a few hours of labor to shore them up, and a new coat of paint and they are good as new.
