An angled roof is a popular roof design that slope in one or more directions. This type of roof is also known as a pitched roof, sloping roof or gabled roof. Other synonyms for angled roof include slanting roof, hipped roof, shed roof, gambrel roof and mansard roof. A slanting roof typically has a steeper pitch than a gabled roof, while a hipped roof has slopes on all four sides. A shed roof is a single sloping plane that is often used on small structures. The gambrel roof has two slopes on each side and is commonly used in barns, while a mansard roof has four slopes and is popular in French architecture.
