If you take a look at some of the most prestigious buildings in history, you’ll notice many of them share one unique quality: they incorporate copper into their architectural designs. From the US Capitol to the Belvedere Palace, many structures around the world have used copper for its durability and striking beauty.
Another historic building that can be added to the list is the Arizona State Capitol building which features a dome made from Copper roofing panels proudly supplied by Western States Metal Roofing. Since Arizona is known as the copper state, the dome is especially fitting.
We recently caught up with Mike Butcher, Sheet Metal Superintendent, and Ron Giesler, Project Estimator, of Progressive Roofing, which were the installers of the new copper dome to learn more about the project.
How Was The Dome On The Arizona State Capitol Installed?
Prior to the new installation, the old Copper dome needed to be removed. The state of Arizona wanted a shiny copper appearance, but the old copper roof had begun to patina. It no longer had the appearance of a shiny copper penny. The sealant process on the last dome, which was not installed by Progressive Roofing, did not work and resulted in the dome needing to be replaced prematurely.
