A gable is the triangular upper part of a wall that forms the peak of a roof. It is typically found in buildings with a pitched roof, where two sloping sides meet at the top. Gables can vary in style and design, often featuring decorative elements like windows or trim. Gables serve both functional and aesthetic purposes. They help to shed water and snow, preventing buildup on the roof. Additionally, gables can enhance the architectural appeal of a structure, contributing to the overall style, such as in Victorian or Colonial homes.
