What type of roof design is characterized by two slopes on each side?

A roof design characterized by two slopes on each side is known as a gable roof. This style features two triangular sections that extend from the top of the roof to the eaves, creating a distinct peak at the center. The simplicity of the gable roof allows for effective water drainage, minimizing the risk of pooling water and potential damage. This design is also popular due to its straightforward construction and the aesthetic appeal it adds to homes, contributing to good ventilation and the potential for additional attic space.

In addition to this, gable roofs can be easily adapted for various architectural styles and climates. This adaptability makes them one of the most widely used roof forms in both residential and commercial building. The other roof types listed—flat roof, hip roof, and mansard roof—differ in structure, features, and functionality, emphasizing the unique aspects of the gable design in comparison.
