Double wide Mobile home roof
I've got a doublewide that has no access to the attic area, plus a lot of it has vaulted ceilings so there is no room up there to start with. When I reroofed this place a few years ago I had to replace some of the decking. I noticed that the insulation in the ceiling was next to nothing but didn't do anything about it at that time. Years later after a lot of high utility bills I have decided to insulate the roof. After talking with different contractors the best way to do this for the best performance was to use closed cell foam. Their idear is to use 2 x 4s on top of my shingles with the 3 1/2 side standing up and build a frame work on top of the roof, then spray the foam between the 2 x 4s directly on top of the shingles and then I plan to top that with a metal roof. Has anyone seen this done before or do you think I'am wasting my money? Would appreciate any comments.
