An eave is the part of a roof that overhangs the walls of a building. It helps to direct rainwater away from the structure, preventing water damage to the walls and foundation. Eaves can vary in design and size, depending on the architectural style of the building. Eaves are often found in various types of buildings, including residential homes and commercial structures. They can be adorned with decorative elements, such as cornices or gutter systems, which enhance both functionality and aesthetics. Properly designed eaves contribute to the overall durability and appearance of a building.
