Thought of passing this item on to you all, with the
hope that other ideas get passed on.
Went to a local DIY store (Homebase)
Didn't find what I wanted, typical, but did find this.
Shelf Liner Clear.
£3.50 for 1200mm x 450mm.
Don't worry it won't go into lining a drawer or shelf.
It will make excellent roofing in 28mm 'scale'.
Should paint up nicely as pantiles, but I think it would
also make modern clear plastic roofing. You could even
paint most of it as asbestos leaving rectangles as Sky-lights.
