The area subject to a search warrant is defined by the warrant itself. If the warrant is for the entire address, then the police have the power to search everywhere at that address. The real question is whether evidence found in your room could be suppressed on the grounds that the warrant was constitutionally infirm in that it was not sufficiently specific in not excluding your room. I doubt you would win on that one, but to be sure would require a significant legal research project that is far beyond the scope of a free LawGuru question and answer.
