Yes, it would take all day to get my roof back to it's original colour (and it is only 5 months old).
However, I probably would only go to that excessive degree of labour if I was adding a UV protectant onto it after cleansing, but I don't think I will be doing that soon.
I called the manufacturer of my roof (Alpha-ply) and the nice lady I spoke with told me that the whole roof is UV resistant and does not need applications of protectant until the thin white topcoating starts to wear and the black rubber is showing through.
So, I guess I will be satisfied with my light grey roof, complying somewhat to the latest dogma, 'Dirty Is The New Clean'.
Sounds good to me
