A butterfly roof is a style of roof design that features two roof surfaces that slope inward, creating a V-shape or butterfly-wing appearance when viewed from the side. The two roof surfaces typically meet at a valley in the center of the roof, and the outer edges of the roof can extend out to form eaves or overhangs. The distinctive shape of a butterfly roof allows for high ceilings, plenty of natural light, and increased ventilation. Butterfly roofs are often used in modern or contemporary architectural designs and are commonly seen in areas with high winds or heavy rainfall. However, they can be more difficult to construct and maintain than traditional pitched roofs.
