I am not sure if this is what you are looking for, but wouldn't you get what your looking for (and avoid the subquery) by WHERE'ing roles.id IS NULL? Maybe I am misunderstanding what data you are trying to pull as the "where user_id = 3" in the subquery is a bit confusing to me, are you running that query for each user_id ?
