Final answer:
A roof that slopes on all four sides is known as a hip roof, providing stability, aesthetic appeal, and effective shedding of water and snow.
Step-by-step explanation:
If a roof slopes on all four sides, it is called a hip roof. This style of roof is characterized by the slopes that all descend toward the walls of the building.
It's a popular design that not only adds aesthetic appeal but also provides stability and resistance to wind. Unlike gable roofs, which have two sloping sides and two vertical sides, hip roofs are sloped on all sides, often with a gentle pitch. This type of roofing is commonly seen in residential homes and is particularly effective for shedding water and snow.
