What does a gable roof include in its structure?

A gable roof is characterized by its two slopes that meet at a peak, forming a triangular shape at each end of the structure. This design not only provides an aesthetic appeal but also serves functional purposes such as effective water drainage and enhancing durability against harsh weather conditions. The two slopes create an overhang that helps protect the walls from rain and snow, minimizing the risk of water damage.

In contrast, a single slope is typical of a shed roof and does not form the traditional gable shape. Similarly, a roof with multiple angles would suggest a more complex design, such as a hip or mansard roof, rather than the straightforward triangular formation of a gable. Finally, a roof with no slopes would not fall under the definition of a gable roof at all, as gables rely inherently on the presence of slopes to define their structure. Thus, the defining feature of a gable roof is indeed the two slopes meeting at a peak.
