Copper roofs can be designed to meet or surpass other materials in terms of energy savings. A vented copper roof assembly at Oak Ridge National Laboratories (U.S.) substantially reduced heat gain versus stone-coated steel shingle (SR246E90) or asphalt shingle (SR093E89), resulting in lower energy costs. [90] Types of copper roofs include: [91]

Their waterproofing principles may involve overlapping, stapling, the application of elastomer seals, etc. Some traditional roofing materials, such as thatch or green roofs, do not fit into these two categories.
Depending on metal prices, copper may be a very cost-effective cladding and roofing material. With good building design, materials choice and craftsmanship, copper roofing or facade cladding may be cheaper than slates or concrete tiles, especially when one takes into account the lasting colour, durability, maintenance-free and lightweight ...
The Rotunda is a building located on The Lawn on the original grounds of the University of Virginia. Thomas Jefferson designed it to represent the "authority of nature and power of reason" and modeled it after the Pantheon in Rome.
