You don't. A copper roof is supposed to turn brown and then slowly turn
a light blue/green over the years. You can wash it in venegar and salt
every few months to get some copper color back but that just delays the
inevitable.

We moved into a new house that has copper roof above 2 dormers. It is
tarnished and weathered (about 8 years old). I have seen similar roof
adornments in the Raleigh, NC area that absolutely shine, and I like the
look.

How does one go about polishing, and retaining the shine?

Thanks, Jeff
