A roof eave is the part of a roof that overhangs the walls of a building beyond the edge of the roof. It is designed to keep water from running down the walls of the building and to provide shade from the sun. The eave is usually made of a material that is heavier and more durable than the rest of the roof and is supported by a series of brackets or rafters. The eave can be used to add architectural interest to a building and can be decorated with moldings or other trim. It can also be used to provide shelter for outdoor living spaces, such as a porch or patio.
