A gable roof consists of two sloping roof planes that intersect
along the ridge to form an inverted ‘V’, i.e. a Λ-shape.
The triangular portion of a facade above eave level between intersecting roof
planes is called a gable.
Due to its simplicity, the gable roof is the most common roof type you’ll see in Belgium and the Netherlands.
Generally speaking, the gable roof’s roof planes are symmetrical, but when its roof planes vary in length and/or pitch (slope), you refer to it as an asymmetrical gable roof or catslide roof.
