Eaves are the edge part of a roof that projects out horizontally beyond the side of a structure. They can have practical functions, such as to provide shade and protection from rain, as well as aesthetic functions.

An eave is different from a cornice, which forms part of the entablature in Classical architecture, and over time has come to refer to the underneath area of the roof formed when the ends of the rafters hang over the exterior siding. From the inside, the eave is the angle where the roof meets the external wall.

The eave’s width is related to the roof pitch. The steeper the pitch is, the narrower the eave.

= Types of eaves =

There are four basic types of eaves:

* Exposed: The finished underside of the roof and supporting rafters are visible from underneath.
* Soffited: Includes a soffit – the panelling which forms the underside of the eaves, connecting the bottom tip of the eave with the side of the building at a 90-degree angle.
* Boxed-in: Encases the roof rafters but meets the side of the building at the same angle as the roof pitch.
* Abbreviated: This is cut off almost perpendicular with the side of the building.

Most types of eave include a fascia, which is a horizontal board that runs around the building to cover the ends of the extended rafters.

Exposed, soffited and boxed-in eaves contain air vents to prevent overheating and condensation forming. Under roofing material and wrapped over the edge of the eave, flashing is installed to prevent wind and water damage. Eaves can also be designed to incorporate guttering, which conveys rainwater to tanks or drainage systems.

= Purposes of eaves =

Eaves prevent rain, snow and other debris from causing leakage-related damage to the building or the foundation, by projecting it out and away from the side. This prevents water from pooling around the footings and encouraging decay.

Eaves can also provide shading to windows, helping to maintain a comfortable internal temperature. Therefore, well-placed eaves can have a significant effect on the thermal efficiency of a building. It is good practice for eaves on north-facing windows to have a width of 45% of the height measured from the bottom of the window to the top of the eave.

Aside from practical functions, eaves can also be used to help define the architectural style of a building.

For example, Dutch Colonial houses featured flared eaves that curved up and away from the roof; the architect Frank Lloyd Wright often used sweeping, elongated eaves in his Prairie house designs; and traditional Asian pagodas are defined by tiers of multiple eaves. A-frame houses include eaves that can reach ground level. A characteristic element of the Italianate style is buildings with decorative, overhanging eaves on a slightly pitched roof.
