Copper is an extraordinarily soft and durable material, requiring no extra surfacing. Low mass of roof cover has a positive influence on static qualities of an object. Roof span, which is expensive to construct, is therefore not required. Copper roofing is resistant to extreme meteorological conditions and is suitable for use in mountainous areas and northern countries where adverse climate conditions are common. Due to its inherent qualities copper is used in restoration of historical and memorial constructions of high importance. Copper is a justifiable investment with a warranty period of 130 years. Copper is completely corrosion- resistant, therefore no further investment for roofing will be needed. It is even true that copper is among the most cost-effective materials for roofing and facade cladding.
