In New Zealand, a curved roof is commonly referred to as an “arched roof.” This term is used to describe a roof design that has a curved or arched shape rather than a traditional flat or sloped design. Arched roofs can add architectural interest and visual appeal to a building, and they are often used in contemporary or modern architectural styles. The specific type of arched roof can vary, such as a barrel vault roof, a dome roof, or a curved truss roof, depending on the desired design and structural requirements of the building.
