The tv anchor said "Roads are crowded during peak hours"
When changing this to reported speech does the tense change i,e does "roads are" change to "roads were"?

Yes, that's right.
So when I report on your original quote it becomes, "The TV anchor said that roads were crowded during peak hours."
Here's a good page on reported speech with clear examples and even exercises for practice:

Hope this helps! :)
Yes, generally, but it really depends on the context.
In the context of your particular example it's not absolutely necessary to switch to the past tense because in this situation, what the reporter said is something that is still true, and will likely remain so for the foreseeable future.
So, you could say this, and it would not be wrong
The TV anchor said that roads are crowded during peak hours
You could also switch it to the past tense if you want, and that wouldn't be wrong either.*
However, if it's something that happened a while ago and is no longer currently happening, then you should switch to the past tense.
For example:
The reporter said, "There is a hostage situation and the police are surrounding the building"
In reported speech after the event, this would become
The reporter said that there was a hostage situation and the police were surrounding the building.
*Note: I can also think of a few extreme scenarios where using the past tense might not be considered correct at all. For example: Einstein said "Energy is equal to mass times the speed of light squared". To use was to convert this into reported speech would be very odd, IMHO, since Einstein was talking about a universal truth.
