What about using some of that clear plastic corrugated roofing

Clear plastics never last as well under UV exposure as something
opaque. If it's reachable, the extra brittleness in a few years can
lead to broken panels.

Galvanised corrugated iron. Traditional and you can paint it (after a
few months) if the shininess offends. What's more in 100 years time it
will have rusted away to nothing whereas the clear plastic or the
Onduline or whatever will be in a landfill or a hedge somewhere.
