The polycarbonate panels on my run roof were designed for green houses, so made to withstand UV. After 2 summers, they have not become brittle at all. They were, however, expensive: $55 each, and I needed 8. Not a cheap roof.
We recently reclaimed some metal roofing from an old farmhouse. When the tarp on the other half of my run gives out, I'll be replacing it with some of those. The white underside of the metal will brighten that area, I hope. I use some white Christmas lights in there in the winter. Because of the low sun angle, it gets gloomy in there.
