I agree that anything other than a new roof will be a compromise and will look patched together. While not ideal, a shed roof extended over the new addition would give the OP a 2/12 pitch, maybe 2.5/12 pitch. In our area here in the south, a lot of double-wides have 2/12 pitch roofs without leakage issues. That shallow of a pitch would be more of an issue in a place that gets lots of snow. The shed roof over our back porch is a 3/12 pitch and is no problem at all.I would second the new roof concept, getting trusses premade would make it a big, but not gargantuan job. You would have a much better performing, looking, place when you got done. The difficulty is that the current roof peak elevation isn't enough to get you good drainage all the way out onto the new addition.
A separate place over a new garage kills two birds with one stone, though!
