A good washing or two with baby shampoo and vinegar - could also use any decent car washing fluid. Rinse very well - then a coating with Zep, 303 Protectant or any good quality liquid wax/sealer - put it on with a mop to make it a little easier. While your up there check your seam sealants really well - best to clean those up and re-seal as necessary ...

If you have a rubber membrane roof, that's UV light breaking down the rubber.

I had a lot of this on mine and decided to re-coat it. I'm very pleased with the results, and no more white streaks.

It won't do MACH 2, but I can get a sandwich and take a pee.

Regular washing with a good car wash liquid is the only way I've found!

If fiberglass, Country Coach Inc recommended applying Formula 303 a couple of times per year.

Once the fiberglass (or the roof paint) begins to chalk, the only permanent solution is to re-paint it. Dicor makes a Fiberglass Roof Coat (paint) that works well, though it is pricey. You could also use a marine deck paint or an automotive paint, anything intended for exterior use in full sun. Just clean & prep the surface and paint. I did mine in about 6 hours, including a second coat.
