roof pitch

[Bob]

Hi
I need to change the roof pitch on a double wide from3/12 to 4/12 or greater to move it to property.
Has any one heard of this and is it a major head ache or just like a stick built house roof............. Only different that is has to be separated to move.

Thanks

I wonder if you could do an overlay with something like Ondura panels (very light) on a framework over the existing roof. Otherwise this sounds like a HUGE undertaking.
