Copper roofing is the one of the most durable, low-maintenance types of roofing available. On very low slopes, copper pans are locked and soldered to form a network of reinforcing joints, its anchor points being within the locks and covered. As the angle of the slope increases above 9.5 degrees, double-locked, vertical, standing seams are employed in which the anchor points are interior to the seams and fully covered. No externals fasteners are used. Copper is one of the most versatile and durable construction materials used. It has been estimated that 85% of the copper smelted since the Early Bronze Age, 5300 years ago, is in use today.
