Roof

A roof (pl.: roofs or rooves) is the top covering of a <a href="/facts/Building/edSjKXje">building</a>, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against <a href="/facts/Rain/MLqcQEyx">rain</a>, <a href="/facts/Snow/HEFKcgIB">snow</a>, <a href="/facts/Sunlight/WPkJRC7s">sunlight</a>, extremes of <a href="/facts/Temperature/QyGe4gmj">temperature</a>, and <a href="/facts/Wind/Nt0QIu5B">wind</a>. A roof is part of the <a href="/facts/Building_envelope/CMRlLol6">building envelope</a>.
The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials and the local traditions of <a href="/facts/Construction/58eqDhy9">construction</a> and wider concepts of <a href="/facts/Architectural_design/BYDabWEy">architectural design</a> and practice, and may also be governed by local or national <a href="/facts/Legislation/yUjkPsgX">legislation</a>. In most countries, a roof protects primarily against rain. A <a href="/facts/Verandah/TqpLNYnz">verandah</a> may be roofed with material that protects against sunlight but admits the other elements. The roof of a <a href="/facts/Conservatory_(greenhouse)/GUuIkqA1">garden conservatory</a> protects plants from cold, wind, and rain, but admits light.
A roof may also provide additional living space, for example, a <a href="/facts/Roof_garden/bMwoVpHF">roof garden</a>.
