Eaves – Functional and Decorative Detail in Architecture

The lower edges of the roof slope extending beyond the side of a building and overhang the face of the wall to protect it from rainwater running off. “The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems. […] The eaves may also protect a pathway around the building from the rain, prevent erosion of the footings, and reduce splatter on the wall from rain as it hits the ground” (“Eaves” 2021).

In wooden constructions, eaves can also form a canopy (drip), a narrow, single-pitched roof, overhang at a certain height on the external walls of the building, most often between the gable and the wall (in Poland). It can also be based on the ends of the beams or logs or on special short corbels, called crosses. In taller wooden buildings, eaves protect the wall or its fragments, most often the foundation, against rainfall, and also act as an architectural division.

A single-pitched or gable roof over a gate, wicket, wall or fence is also called a drip or eaves canopy.
