Definition
A gable wall is the wall that forms the gable end of a building. It supports the roof and encloses the space beneath the gable. Think of it as the main structural element creating the 'face' of the house under the roof's triangle. It bears the load of the roof and protects the interior from the elements. A gable wall is distinct because it rises to meet the sloping roof, forming the gable shape. Unlike other walls, it has a triangular section at the top.
