What is Eave?

An eave is the part of a roof that extends beyond the exterior wall of a building. It forms the roof's edge and helps shield the structure from the elements.

Definition

An eave is the overhanging edge of a roof that extends past the exterior wall.

Purpose

Eaves are used to keep rainwater away from the walls, windows, and foundation of a building. By extending beyond the wall, they provide some protection from rain and direct sunlight.

Eaves can also help reduce water-related damage to exterior surfaces over time. In many buildings, they are designed to work alongside gutters and downspouts to manage roof runoff more effectively.

Examples of Use

Residential homes: Roof eaves extend beyond exterior walls to help protect siding from rain.
Commercial buildings: Eaves are designed to direct water toward gutter systems.
Architectural design: Deep eaves can provide shade and help reduce heat gain through windows.
