What is a gable end on a building?

A gable end is an untiled side of a gabled roof. Gabled roofs are a triangular type of dual-pitched roof with roofing tiles on two sides. The tiled sides often protrude past the body of the building, and the gable end is installed beneath the protrusion.

The steep point of a gable roof is useful in areas with high winds or heavy snow. The shape stops wind, allowing snow to fall to the ground. On modern houses, the tiled sides of the roof do not always protrude beyond the gable end, which can make it vulnerable to failure in hurricane conditions.
