There are two options:
1) store the role in the same place where you store the user (you didn’t specify where it comes from - local database, oauth, whatever) and get the role as a user attribute in req.user
2) make a table in your database where store roles for each user - store roles for each id. if necessary, get a role to make a request to the database with an id from req.user, get roles and do what you need.
The UI can get roles either from a token (if for example it's OAuth/OpenID) or make a request to the server when loading the application/login and get the roles from there.
