Chimney Cap Patina

In the 1980’s builders almost completely quit building chimneys out of brick and mortar and converted to prefabricated metal chimneys.  The tops of chimneys now being metal are subject to deterioration, especially near beach, where salt air chews them up.

We get calls to replace them and copper is the most durable under beach conditions. Here is one we installed in summer of 2023 and now you can see the patina that has developed.
