Pinnacle Roof is covered with Black Spots

I was on the roof of our Pinnacle today doing some cleaning of leaves and debris and noticed the Roof Membrane is covered with small black spots.

Is the normal?

Something I should worry about?

With a unit that new I would think it would be mold, not the black wearing through. Probably just needs a good cleaning.

What is the best way to clean up the mold spots on the roof?

I've had success removing black mold spots on the rubber roof with Clorox Cleanup and a scrub brush. Wear old clothes.

Rob, The service manager from my dealer and one of his crew come to my home base twice a year and clean and treat my roof. I have a vertigo problem on occasion and don't want to be on the roof when it happens, so I don't go up there. They use bleach and a pretty good concentration and brushes with long handles and it cleans right up. After a good rinse they use rubber roof treatment and it looks good as new. This treatment every six months is required to keep the 12 year warranty in force. He also checks all caulking while up there. He charges $300.00, but then again he comes to me and I have a good witness that the required service has been done. I know I could do it cheaper, but again I don't do well with heights anymore. They also wash the entire rig at the same time working their way down. He always wants me to put my awning out since the bleach they are using on the roof helps to clean the awning as well as the slide toppers.

I'm sure he would do two at the same time.

I get the little black and gray spots on my roof too. They come off with spic and span which is the recommended cleaner by Alpha systems. What I have found is that by wetting the roof down then scrubbing and going back over the roof again after the initial scrub the roof really gets nice and clean. I do not re-apply, but go back over the soaped up areas. I have not used bleach as I was afraid of any adverse effects on the sealants or material. The spic and span has done well on my unit so I will keep with it.

Keep in mind that it does get slcik up there, so be careful if doing it on your own.
