I was planning in the not so near future to put a new roof on the ol' doublewide. I was thinking of stripping the shingles, putting down an inch or two of Styrofoam with steel roofing on top.
Dow tells me: STYROFOAM (TM) Extruded Polystyrene Insulation has a maximum use temperature of 165 F. Please assure that adequate ventilation is created between the insulation layer and the metal roofing so that the temperature will not exceed 165 F.
Also I've had some ants that like to nest inside a foam insulated steel door, leaving the insulation outside on the ground. They said: "Design your new roof in such away that the insulation is encapsulated in metal or treated lumber that will deter ants."
I don't like the idea of not being able to walk on the new roof. And I have no idea how to ant proof an entire roof area. Ideas?
