After exploring many options I decide to redo the roof in corrugated metal sheeting. This will withstand the wind better and is lighter than covering the roof in plywood.
Rhino Steel Cladding (see suppliers page) have cheap sheets which are ends of rolls. The finish colour may vary but they are galvanized and perfectly usable.
I needed to strip the roof and install timber purlins for the sheeting. I borrowed a mobile platform so that this could be done from below.
You can also see that the end walls have been partly clad in scaffold sheet secured with battens. The rest will be finished when the walls are clad.
