Restore/replace ESPN rubber roof

I found a document on an EDPM manufacturer's website several years back that detailed what to do with these roofs. First thing it said was to NOT clean with anything but something like blue Dawn (no additives) and a SOFT brush. Anything with additives will speed up the natural ablating process of the EDPM. The material will loose it's white covering (over the black membrane) over time - that's normal aging and is supposed to not happen for many years. Anything that accelerates this (cleaners with additives, hard scrubbing) just lessens it's useful life. Dicor came out with it's cleaner because of demand, not because of actual need. Dicor's coating product adds a new ablative layer that will prolong the black membrane's life, but like already mentioned, it won't fix tears.

IMHO, I've never been able to understand why some MUST have a pristine, white roof - maybe their afraid of someone taking drone photos of their rigs or something. I've also read of several using the replacement roll on roof material (Rino brand?) with good results. I'll probably go that way if we need to replace ours.
