How do I clean roof of copper bay window?

We have copper roofs on two bay windows in the front of our house. They're not looking so great. Anybody got suggestions on how to clean them? Any guesses on replacement costs/pain? Could a regular roofer replace them, or is this a specialist job? Thanks for the help!

    I've got the exact same problem and discovered something interesting. In using a light pressure cleaner, ours turned out to be actually a grey metal with a copper-looking coating. Of course, the pressure cleaner blew the coating off the edge and now we REALLY have a mess! I'll be talking to roofers in the near future to see what can be done. What state do you live in?

    Hi:
    We live in Fairfax VA.

    I searched the list and found a roofer that listed copper roofs in the service provider informaiton and had several good reviews. We're getting an estimate this weekend.

    As long as the roof kit is actually copper and you don't mind getting on a ladder to clean them, a metal cleaning/polishing compound should bring the copper right back to like new condition. A small list of tarnish removers would include, Brasso, Tarnex, Neverdull, Mothers, etc. There are also some less caustic remedies if you look in those household cleaning books that would be a little more environmentally friendly.

    Copper is expensive right now so replacing them just because they are tarnished would not be advisable.

    Once the copper is to a color that you like, apply a clear shilac or other coating over top the bare copper to maintain the finish and keep it from oxidizing.

    Here is a non-toxic version of the cleaner.

    Copper Cleaner

    Rub lightly with fine table salt wetted with vinegar and lemon juice.

    HMMM, I thought the reason for copper anything was to enjoy the patina. Seems if copper was meant to remain shiny it would have been sealed with a product to protect its lusture.

    IMHO, avoid using TarnX ; if it ruins sterling silver, who knows what it will do to copper. .....which reminds me, DD gave me a piece of copper garden art & it's looking really ugly. I need to add something to hurry along it's patina process. sigh, a brass door knocker needs polishing tho [:)]
