Synonym discussion
Sense: noun/1
All three words refer to an outdoor surface area on top of a building, but with different emphases. 'Roof' is the broadest term, referring to the entire structure that covers a building, whether flat or sloped. 'Rooftop' specifically highlights the outer surface as a usable or occupiable space. A 'terrace' is a paved outdoor area that may be on the ground floor or on a rooftop, often furnished for dining or relaxing. A 'deck' is a flat platform, usually made of wood or composite material, built onto the roof of a house. For example: 'We had dinner on the hotel rooftop,' 'She sat on the terrace with a cup of tea,' and 'They built a wooden deck on top of the garage roof.'

Etymology
Formed in English around the early 1600s from two Old English words: 'roof' (from Old English 'hrōf,' meaning the top covering of a building) and 'top' (from Old English 'top,' meaning the highest point or summit). Originally it meant the highest part of a roof, and later came to refer to the outer roof surface as a place people can use.
