Copper with standing seams covered some of the more notable early American roofs including that of Christ Church (17271744) in Philadelphia. Flat-seamed copper was used on many domes and cupolas. The copper sheets were imported from England until the end of the 18th century when facilities for rolling sheet metal were developed in America.
