Roof
A roof is an architectural feature of a building.
Roofs come in several different styles such as hip and gable. The Sims 2: Bon Voyage and The Sims 3: World Adventures allowed a roof type with pagoda-style eaves.
Several expansion packs allowed objects, such as weather vanes, to be placed on roofs.
In The Sims 2: Seasons, roofs are crucial to keep the elements out.
