What is Gable?

A gable is the triangular section of a wall that’s typically found at the end of a building where two roof surfaces meet and rise to a peak.

Definition

Gable is the triangular wall section beneath the peak of a sloping roof, commonly seen on buildings with pitched roof designs. Depending on the building's design, gables can be simple and functional or become a prominent architectural feature.

Beyond their distinctive appearance, they play an important role in shaping the roof structure and can influence how a building handles weather, ventilation, and interior space.

Purpose

The main function of a gable is to support a sloped roof, which helps rain, snow, and debris drain away more efficiently than a flat roof. This can improve the performance of the roof and decrease maintenance in the long term.

Gables can also give extra space in the attic, create openings for ventilation, and add to the architectural design of a building. There are various types of gables that can alter the look of a building without changing its purpose.

Examples of Use

A house with a steeply pitched roof may include front gables to enhance its curb appeal and create additional attic space.
Builders often add ventilation openings within a gable wall to improve airflow in the roof cavity.
Many traditional cottages and farmhouses feature prominent gables as a defining architectural element.
