Eave

In Plain English

The lower edge of a roof that overhangs the wall — where gutters are typically attached.

Definition

The lower edge of a roof that projects beyond the exterior wall, directing rainwater away from the foundation. Eaves can be open (exposed rafter tails), boxed (enclosed soffit), or clipped (minimal projection). In cold climates, eaves are vulnerable to ice dams; proper insulation and ventilation prevent warm air from melting snow at the roof surface and refreezing at the cold eave.

Example

The 2-foot eave overhang provided shade for the south-facing windows and helped prevent ice dam formation on the low-pitched roof.
