was thinking very hard :
I have a large shed (far too large to consider re-roofing) which has a
corrugated asbestos-cement roof that probably dates from the 60s. It's
in quite good condition but there are a couple of cracks and one 4"
hole 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?

Box section, corrugated painted metal roof as a replacement, it is not
that expensive.

Drips condensation during cold weather though.
