By default each role that you create does not have any permissions over the CMS. This means that you should go and set the permissions manually. If you have several pages that are child pages of root item you could use inheritance option which will save time. For instance the permissions that are set to "All Pages" applies to all child nodes until you break the inheritance. Another option is using the built in everyone
role. Note that permissions set to this role applies to all custom roles you have created.
