Roof over on Mobile home

The roof would need to be self supporting. A common method is a row of 4 by 4's down each side of the house that support the roof so that it does not actually sit on the house.
The floor system and the headers over the windows and doors in this house are not capable of carrying the extra weight.

You can put a gabled aluminum roof over directly on the existing bow roof. If your a Do-It-Yourself type you can find aluminum pan roof kits locally in some areas or online. What part of the country are you located? I will see if I can recommend a contractor or kit-fabricator near you.
