What is the term for the edge of a pitched roof that overhangs an outside wall?

The term for the edge of a pitched roof that overhangs an outside wall is "eaves." Eaves are designed to extend beyond the walls of the building, providing protection from the elements, such as rain and snow, by directing runoff away from the foundation. This overhanging design helps to prevent water damage to the walls and the structure below. Additionally, eaves can contribute to the aesthetic appeal of a building, offering a finished look to the roofline.

Regarding the other terms, decking refers to the flat surface that makes up the roof before roofing materials are applied. The ridge is the highest point of a pitched roof where two slopes meet. A facade generally refers to the front or outward appearance of a building, often focusing on the vertical structure rather than any overhanging roof edges. Understanding these distinctions is crucial for grasping architectural terminology related to roofing and building design.
