There are several common types of roofs, each designed for specific climates and architectural styles. The gabled roof features two sloping sides that meet at a peak, allowing for efficient water drainage. Flat roofs are often used in commercial buildings and are easier to construct, but they require proper drainage systems to prevent water accumulation. Another popular option is the hip roof, which has slopes on all four sides, providing stability and durability against strong winds. The mansard roof includes a double slope on each side, offering extra living space in the attic. Each roof type has its advantages and is chosen based on aesthetic and functional needs.
