To properly understand what’s involved in achieving a copper roof patina one must first understand copper.
Copper is an extremely durable and versatile metal that can last close to one hundred years and even after can be recycled and almost one hundred percent reused.
The thing about copper that a lot of people love is that its natural coloring is very sensitive to the air and certain elements of the air that are geographically relevant, as well as that areas humidity. The environment will affect the color and the rate at which the copper changes colors.
That being said it is still possible to use chemical treatments to advance this copper roof patina process. It’s even possible to choose the color of a coppers patina through chemical treatment. There is, however, a major caveat to that unnatural choice.
Coppers natural patina occurs as a gradual progression depending on the coppers physical orientation and the local weather and pollution levels on a grading scale of lighter and lighter greens. The copper roof starts out salmon pink brown and makes it’s way to the statue of liberty bright green.
As I said before, you can alter the coppers color via chemical treatment but here’s the catch, unlike the natural progression of the color from salmon pink to bright green , when you do a chemical treatment to change the patina over the course of a few months, the processes will need to be repeated a certain amount of time later. It will depend on the geographic characteristics as discussed above if you wish to maintain that chemically chosen patina. In closing, you can achieve your desired color of copper roof patina, but it is not as long lasting as the natural patinas are.
