I have a large shed (far too large to consider re-roofing) which has a

where a pipe used to pass through.
It seems the repair options are either Flashband (+primer), an EPDM
patch, making a GRP patch, covering with a bit of corrugated roofing, or
using galvanised mesh and cement. What else should I be thinking of? Any
recommendations?

If replacement isn't practical, a cheap effective option is:
Apply bitumen paint
Apply cloth
Apply bitumen paint
Sprinkle on sand.
