I've just realised that what I thought was a piece of rag hanging down from
the conservatory roof is, in actual fact, the piece of 'plastic?' which
seals the end of the polycarbonate roof sheet. It must have come away when
the edge of the roof was weighted down with snow and icicles.

Is it possible to fix this? And if so, is there something special to buy?
Does it require any special method to fix?

Cheers
