A projecting cornice on a building has the function of throwing rainwater free of the building's walls. In residential building practice, this function is handled by projecting gable ends, roof eaves, and gutters. However, house eaves may also be called "cornices" if they are finished with decorative molding. In this sense, while most cornices are also eaves (in that they overhang the sides of the building), not all eaves are usually considered cornices – eaves are primarily functional and not necessarily decorative, and a cornice has a decorative aspect to it.
