The word "roof" refers to the upper covering of a building or structure. It serves as a protective barrier against the weather, providing shelter from rain, snow, sunlight, and other environmental elements. Roofs can be flat or sloped and are made from various materials such as shingles, tiles, metal, or thatch.
The word "roof" originates from the Old English "hrof," which is related to the Proto-Germanic "*hrūfa." It is also connected to similar words in other Germanic languages, such as Dutch "roof" and German "Dach," all of which denote the upper covering of a structure.
