First, are you talking about a Roku player or a Roku TV? Second, if it's a Roku TV do you live within the broadcast area for that station? There are very few TV stations that provide a way to stream their station online.
If you're using a Roku TV and you're within the expected coverage of the TV station, a channel scan should identify the station and allow you to view it. If for some reason you are within the area but still can't receive the station, remember that TV signals are line of sight, and even minor hills can block the signal from being received. At my home, the closest TV transmitter is the only I have the most trouble receiving over the air. There's a ridge between my home and the antenna, and it causes problems.
Remember too that all TV broadcasts are digital. With the old analog system, it was possible to still watch a marginal signal, albeit with a less then stellar picture and sound. But with digital, once the signal drops to a certain point, it's just gone. You either get the signal and can watch something, or it's like it's not there at all. They call this the "cliff effect", as in the signal disappears like it fell off a cliff.
