exterior of a mobile home
I have been asked to quote on re-siding and a new roof for an older mobile home. In our climate Cebtral Alberta), it makes sense to add ridgid insulation if a re-siding job is being done. Question one, should the old skin/siding be removed or just go over top? Number two, I would plan on strapping as well as the insulation, what is the suggested thickness for insulation. Third, the client wants to add a peaked roof. I have heard to two ways to do this. One is to go on top of the existing roof with taylor made trusses and the second method is to remove the old roof (or open it up) and use regular trusses. The second is so that you can see any damage, mould, water stains etc.,
All advice is welcome, especially from those who have actually done this type of work.
