What is the eave on a roof?

The eave on a roof refers specifically to the lower edge of the roof that overhangs the walls of a building. It serves several important functions, including directing rainfall away from the walls and foundation, providing shade, and contributing to the overall aesthetic of the structure. Eaves can vary in design, size, and material, but their primary purpose is to extend beyond the walls to protect the building from water damage and improve comfort by providing shade.

Understanding this feature is pivotal in the context of both roofing design and construction practices, as well as in evaluating the impact of weather conditions on a building's integrity. It is common for eaves to support gutters or to be constructed with additional materials to enhance their functionality.
