An addition is under construction to a historic downtown building in
Ann Arbor.  The original building has a gabled roof with the gable
toward the street.  The addition is apparently going to have an
intersecting gabled roof with a gable to the side (facing another
street).

If the new roof were a complete gable, it would probably require
getting rid of the old chimney on that part of the roof.  But
apparently the back wall of the addition drops straight down from the
ridge line.  Arguably, that's kind of clever, if faux.

So no particular problem with the configuration.  What surprises me is
seeing the framing for the new roof laid on top of the asphalt shingle
roof of the original structure.

Is this "junk framing", or appropriate respect for the integrity of
the older building?  Wouldn't it be more correct to at least strip off
the shingles and tie the new roof to the old roof?  Doesn't this
approach risk runoff water getting under the new roof structure?
