removing sheet

[b21playa]

our side utility has a roof made of a upvc frame with what looks like polycarbonate sheets for the glass area.

I need to remove these when i will be moving the toilet and needing to extend the soil pipe

anyone know how to remove the sheets?

if theres no obviouse screws the top may either slide off the bottom or just "unclip" off the top

must unclip off the top as it meets the neighbouring wall and the neighbours have the same thing
