How many eaves does a gable roof typically have?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

A gable roof typically has two eaves, as it consists of two sloping sides that meet at a ridge, creating a triangular shape. Each side of the roof forms an eave that extends beyond the walls of the house, allowing for water runoff and providing some protection against the elements. In residential architecture, this design is common, and the two eaves help to promote effective drainage while also enhancing the building's aesthetic appeal. Other options imply a configuration that does not align with the traditional structure of a gable roof. For example, having one eave would suggest a flat or shed-style roof, whereas three or four eaves would indicate a more complex roof design that includes additional slopes or facets, which is not characteristic of a simple gable roof.
