Definition & Meaning of "gable wall"

What is a "gable wall"?

A gable wall is the vertical wall that supports the gable end of a roof. It typically rises to meet the peak of the roof and forms the triangular shape at the upper part of a building. Gable walls can be constructed from various materials, such as brick, wood, or concrete, and may include windows or decorative elements to enhance the overall design. This type of wall is common in many architectural styles, providing structural support while also contributing to the visual character of a building. Gable walls help with water drainage, directing rain and snow away from the structure.
