The easiest/free way is to connect an antenna into the same TV that you currently have your Roku device attached. You watch them by selecting your ANT (antenna) input. Any antenna should work (even the old rabbit ears). You may need a stronger antenna for better reception of course as situation warrants.
The alternative way is by streaming them through a cable-alternative package that provides local channels. These are the paid alternatives and you then stream through the Roku.
The Roku device itself does not have an internal TV tuner, so either need to use your TV with a connected antenna, or purchase a cable-alternative streaming package that provides local channels.
