I wish to re-roof an addition to my home using corrugated steel roofing panels. How do I join/seal the new roofing to the existing asphalt shingle roofing at the joint?

It depends upon what angle they are joining from. In most cases, though, you'll want a flashing of like metal to go under the asphalt shingles and then extend on top of the corrugated.

Thanks for the answer.
It is a very slight angle. There is a slight pitch to the original roof and even less on the addition (it's almost flat).
Won't flashing over corrugated (which will be sitting on top of 1" nailers) look funky?

It sounds like your metal roof will be downhill from the standard shingles. In the case, a flashing like I described is the normal application. The flashing should have a closed hem folded on its exposed edge. This gives rigidity and helps with appearance. You might check with your metal roofing supplier to see if they have a metal or foam closure strip which can be used to fill in the "voids" underneath of the flashing.
