An eave is the edge of a roof that extends beyond the exterior walls of a building. Its primary function is to direct rainwater away from the walls and foundation, protecting the building from water damage. Eaves also provide shading for windows and walls, helping with temperature regulation and reducing cooling costs in warm climates. Additionally, eaves can contribute to the aesthetic appeal and architectural style of a building. The underside of an eave may be covered by a soffit, which can be vented to allow air circulation in the attic.
