In 2012, the cupola of Theodore Roosevelt High School in the Bronx, New York, was restored with a beautiful copper-cladding system. The school, originally opened in 1919, had copper cladding fastened with nails that eventually led to water damage in the wood beneath. The architect’s goal was to replicate the original design while enhancing waterproofing. This challenging project used 20-ounce copper for the standing-seam base, curved cornices, and detailed ornamentation. Standing seam panels were installed at the base, while cornices and flat panels were pre-tinned, overlapped, pop-riveted, and soldered. The dome was also covered with standing-seam panels, and the flat areas were double-locked and soldered for durability.
