A Gable Wall (or Gable End) refers to a wall comprising of a Gable, the triangular section of an end wall between the edges of a sloping roof, and the wall beneath.
The Gable End Wall's shape is dependent on the overall design and structure of the property, including available construction materials and local climate.
A number of variations of the Gable exist, including the crow-stepped gable, consisting of a step-like design. This design is found across England and Wales.
Gable End Walls can be unsuitable for structures exposed to high winds, particularly for less-angled, flatter Gables. As wind flows over the roof, a "lift effect", similar to that of a wing, is created, and can cause the roof to be ripped off in extreme conditions.
