Copper is a natural material that has been used for covering roofs for centuries. Many medieval buildings and churches were roofed in copper and some are still intact today. With longevity and energy efficiency being top priorities when designing and renovating buildings, copper roofing is fast becoming a hugely popular metal roofing option for both industrial and domestic properties. It may be a more expensive choice than other roofing materials, but the advantages vastly outweigh the disadvantages.
