text: Architects often look to architectural copper for continuity in design elements. For example, a copper roofing system may be designed with copper flashings, weatherings, vents, gutters, and downpipes. Cover details may include cornices, moldings, finials and sculptures.
  With the growing use of vertical cladding, vertical and roofing surfaces can run into each other so that complete continuity of material and performance is maintained. Rain screens and curtain walling (often linked with transoms and mullions) are also gaining popularity in modern architectural design.
