If it is EPDM rubber roof, Dicor (maker of EPDM for RV roofs) has a good online resource --> Rudy's Expert RV Roof Care Handbook.
I see that some of the Citrus based cleaners can also be of concern to some roofs - in addition to anything that has petroleum based solvents in the cleaner.
I have used the 3% hydrogen peroxide in the past on some bad staining. Otherwise I regularly use original Dawn dish soap in water with a bristle brush and some elbow grease.
Hope this helps,
Brian

We cleaned the roof of our Silverado this week and both air conditioners are leaving ugly brown streaks. We used Dawn dish liquid with a squirt of bleach along with direct spray from a bottle of rubber roof cleaner and nothing seemed to clean these stains. I would like to remove these ugly stains but I'm more concerned with harm to the roof from harsh cleaners. We've only had it for 3 months and this is its first cleaning. Is this a normal issue with the air conditioners? We've never had this issue with our previous travel trailers and don't know what to do about it.

We have a fair amount of staining from the A/C, although not quite as bad as yours. I remove most of it with Dawn dish soap and a soft brush. If it is really bad I will spot clean with Camco roof cleaner purchased from Wallyworld.
I think a lot of it has to do with the environment you are in. Humid means more runoff. Humid and dusty or dirty, means more stain in the runoff.
I agree with Birchwood, I suggest HL put a pan with a drain hose under the A/C. It could be routed over the edge of the roof, or down to the underside the rig. This would be an inexpensive improvement and good sales tool. Trace

That's looks like a rust stain to me.
My previous big Horn started to stain like that. I took the AC cover off and found leaves and bark that was causing the stains. I clean up the mess and no more severe staining, but I was not able to completely remove the stains. Dirt blowing around, on the AC and on the roof may also cause streaking and stains. Good luck and safe travels.

We had the same stains on our roof. I was trying to clean them on the weekend and could not get them cleaned off. My wife suggested Magic Eraser. We gave it a try and they removed the A/C stains completely.

Be careful with the magic erasers. I used one to remove glue from dealer sticker and scratched up my gel coat.

Simple solution is....Don't wash the roof....It does nothing but remove the wear layer on the rubber roof. Does it really matter if it's clean or not? I didn't wash the rubber roof on my last park trailer in 10 years. Nobody saw it or cared. The roof was still in good shape when I sold it. As the roof ages a small amount of rubber dries out and turns to powder on the surface. It just lies there if undisturbed and protects the rubber underneath it. I chose to just leave it alone.....Don

Yes but where it rains it washes down the sides and creates drip marks and black streaks that are harder to clean off.
