I have a fair lump of rockwool, used as loft/boat insulation. It
might be a bit thick. I'll experiment with planting some stuff in
it. I think grass might be one good bet as it doesn't disappear in
the winter, also it keeps down weeds if you use the right stuff.

I think the loading would then be quite low as long as it is
well-drained. I suspect that it can be kept on the roof by means of
some spikes, so I need a material that is waterproof and spikey.
Can't think of one.

Sharkskin is good.

Wot, off a real shark? Or is this a trade name for some stuff? I've never
heard of sharkskin.

Real stuff of course. Expensive though.
