I am planning a project to cut a hole in the roof of my flatroof garge and add a slide off flat roof section.
Kind of like this one here:

Wondering where to buy V groove castors from and also suggestions on what material to use on the roof itself. It needs to be flat and low profile just like in pics above
Also was thinking of maybe C channel instead of V groove but not sure wat castors/wheels I would need to ue for C channels.
Other challenge I have is the roof itself is currently corrugated sheets of roofing tin. The runout tracks and frame will need to sit on top of this corrugated roof, so trying to figure out how I will seal the sides.
See badly drawn pic attached below.
Any help or suggestions would be appreciate
