What type of roof slopes down only on one side?

A shed roof is characterized by its single-sloping design, which is also referred to as a mono-pitch or lean-to roof. This type of roof features a surface that inclines downward on just one side, creating a simple and functional structure. Shed roofs are commonly used in modern architecture, agricultural buildings, and in situations where a minimalist aesthetic is desired.

The design allows for effective water drainage and can also accommodate larger windows, which can enhance natural lighting within the space. Furthermore, shed roofs can be a practical solution in areas with heavy rain or snowfall, as the slope facilitates runoff and reduces the risk of water pooling. This type of roof is particularly favored for its straightforward construction and versatility, often being utilized in extensions or additions where a vivid style is desired without the complexity of dual-sloped roofs.
