Waze maps are community supported. It's up to us, and now you too!, to create the map using the web-based editing tools. You can record roads in the Waze client (still must be confirmed/saved in the editor), and/or use the editor to update the map. There's a comprehensive wiki which has a load of information you should read before getting too heavy into the editing.
Also, from the client you can Report map update requests, which will put an 'alert' on the map which a local area manager (community member, not Waze employee) can use to fix problems. You can report map problems on the client or via the LiveMap.
Welcome aboard!
