Function
The primary function of the eaves is to throw rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. 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.
The secondary function is to control solar penetration; the eaves overhang can be designed to adjust the building's solar heat gain to suit the local climate, the latitude and orientation of the building, refer to passive solar building design.
The eaves overhang may also shelter openings to ventilate the roof space.

—Susanne K. Langer (1895–1985)
