I'm putting together a woodstore, but am wondering what to use for the
roof, I've been considering ply, but even the exterior stuff will need
felt, it seems. Or would Flexacryl or several coats of exterior varnish be
sufficient?

I had a look at corrugated PVC, but it seems a lot thinner and flimsier
than I remember from use many years ago. Polycarbonate twinwall is
overkill and on the expensive side for this type of use.

Basically It doesn't have to last 20 years, but I'd like it to last at
least 10 before any repairs are needed.

Any other ideas for roofing?

Metal decking. Cost **** all for that size roof, lasts much longer than
40 years, need no structure at all, just a coupla bits of timber. Dont
need any real slope at all, just vary the depth of the timber is fine.
