In roofing terminology, what does the term 'eave' refer to?

The term 'eave' specifically refers to the edge of the roof that extends beyond the walls of the building. This overhang serves several important functions, including helping to direct water away from the walls and foundation of the structure, thereby preventing water damage and promoting drainage. Eaves also often play a role in the aesthetics of a building, contributing to its overall architectural style. By providing shade, they can also help to reduce heat gain in the interior spaces, making them more energy-efficient. Understanding the characteristics and functions of eaves is crucial for anyone involved in roofing, architecture, or construction.
