How are sheet copper roofs typically joined?

• A. With interlocking seams
• B. With standing seams or solder
• C. By nailing
• D. With welding techniques

Answer: (B)

Sheet copper roofs are typically joined using standing seams or solder. Standing seams involve connecting two panels of copper with raised seams that run vertically along the roof, which helps in managing water flow and provides an effective means of sealing the roof against leaks. Soldering is a common technique used with sheet copper, where molten solder is applied to the seams to create a watertight bond between panels. This method not only enhances the durability of the roofing system but also helps to maintain the aesthetic appeal of copper's natural appearance. Using standing seams or solder is particularly important for copper roofs because it allows for thermal expansion and contraction, which can occur due to temperature changes. This flexibility is crucial in preventing warping or damaging the roof structure over time.
