Patina on copper roof
Patina on copper roof
(OP)
Is it possible to analyze a patina (patine) on a copper roof and create a chemical so that a new copper addition will match perfectly?
Thanks,
Tom

Can you get an exact match with the existing roof within a day?

A lot depends on what you have now, which in turns depends on how it was formed over time.
The only problem being is that these solutions have been around for ages and I don't think anyone has improved on them. some of them are like the eye of the gnat and the hair of the frog type mixtures.
I would contact a few of the people who make the conversion coatings and see what they say. From when I worked with it I don't think there has been any change in chemistry.
Here are just two of many supplier out there.

I have had some experience matching patina colors on copper roofs, walls and gutters. The answer that you probably do not want to know, is that you can get close but not exact.
The next question is what is the color? is it green, brown, black, blue or variegated. Chemicals or mixtures of chemicals are available to do this. from several different manufacturers, they will have color chips of what they can do.
The most difficult color to match is the rich mahogany brown of a naturally aged copper roof in a dry inland location.
The easiest is the green patina of a roof near the sea.
