OKURA MUSEUM OF ART was built in 1927, so it has survived for nearly 100 years. It’s time for the renovation of the copper sheet roof. The roof of OKURA MUSEUM OF ART has the jade emerald rust. It takes a long time for a copper sheet roof to become coated with green rust. A copper sheet roof with beautiful green rust has precious value. We have developed a new method which repairs the copper sheet roof. This new method of repairing overlap 2 of copper sheets on the original surface.
