It'll be automated at some point but does anyone have a basic breaking system design that I can use to start with. Don't really want to look at hanging weights, (for the obvious reason), if I can avoid it....

Hi draco,
If you are concerned about the roof rolling away too easily or building up too much speed, then you could simply increase the rolling resistance / friction by either, adding a couple of additional rubber wheels which are adjustable for preload and hence rolling friction on some part of the track, frame or roof structure or you could use a rubber pad with adjustable preload (even a nylon pad with enough preload) against which the roof would slide. Then when you are ready to automate your roof remove the speed limiting devices.
Best
