I agree, changing materials is not a "Preservation" treatment, and is undesirable for a number of reasons.
Unfortunately we are too often at the mercy of the changing times and industries as to what is available. It is one of the ongoing challenges of historic preservation.

AT 77, in private practice for more than 50 years, dealing with such issues as established here, I offer the following. With new technologies, various materials, etc., etc., I have found nothing that replicates the original Copper, Clay tiles. There has been nothing formulated to provide the look of natural petina found on these old tiles. Thirty or fourty years ago, there was no answer. However, with the "market" begging for these old tiles, and our getting the word out to the demolition people, that there is a market for these tiles, they had been transfering to the landfills. We lost many tiles, but slowly, as the word got out, these old tiles being removed from homes, buildings, etc., were finding their way to "resale" locations. With the ever growing need for these old tiles, they are getting hard to find. And, when the old original tiles are gone, there will not be a product to replicate these roofs. Unless new technology provides a means to duplicate the "old patina"???
