How long will it last on decorative copper roofing?

ProtectaClear is not made for copper roofs. It is made to protect metal items that get a lot of use like copper sinks, countertops or jewelry. ProtectaClear is also great to protect stainless steel or mirror polished metals. Everbrite Coating is made to protect copper like copper roofs, gutters and other architectural metals. It has UV blockers and Anti-Oxidants to protect the copper from tarnish. The copper needs to be completely clean and dry. Four coats of Everbrite will provide long lasting protection and will keep the roof copper color and shine for 5 to 10 years. The roof can be maintained by adding another coat every 5 years or so. Just wash, dry and reapply. We have excellent customer service and technical help available.
