ELI5: Does sign language provide the predominant message for hearing impaired people?

Or does the lip reading do most of it and the signs are just there for context?

EDIT: Who the fuck is downvoting this?

Note that there's more than one sign language, just like there's more than one spoken language. Deaf people in the U.S. usually speak ASL (American Sign Language), which isn't the same as what's signed in the U.K., Australia, France, or other countries. Oh, and there are regional dialects, too.

To answer your question, though, all of those sign languages are complete languages, just as rich and expressive as spoken language. There's nothing that can be communicated via speech or writing that can't be communicated between two people who are both fluent in sign language.
