It is not a good idea to wash your RV rubber roof with pressure wash as it may damage the roof. Some products used for cleaning may recommend pressure wash but you need to be more careful and not set the pressure too high.
Make sure the nozzle pressure is set to less than 1200 psi. Pressure washer can bring out water at psi as high as 3100 and that can be very bad for your RV walls and roof. Specially for the RV roof, a high psi can cause damages that can cost you much more to repair.
Remember a RV roof is a critical component of the RV and any leaks can result in water drop and other issue inside the RV. The RV paint and seal can get impacted when the high pressure water hits the roof. And thus high pressure wash may not be considered a safe idea.
Reason why people want to try pressure washer is because it makes the job easier. Pressure wash also removes the tough dirt, removes decals and bird dropping with ease. This may seem like an easy effort but it will result in other issues as mentioned.

Also a RV roof no matter of what type will have things like vents, air conditioner which are mounted with screws or another methods. This may affect the mounting and result in damages to them as well. Small gap or cracks can then result in holes that can worsen.
Caution and keeping a closer look while using a pressure washer is all you need to do. Make sure you have lesser pressure on nozzle just to be sure when washing the motorhome or travel trailer exterior or the rv roof. Having a pressure adjustable nozzle will make your job easy. Just set the pressure to less than 1000 psi and you should be fine.

Going up there can be risky as well when you have splashes of water so just be careful and don’t climb up there. Instead get a ladder go up there at the edge and use the brush with a handle sufficient enough to reach most part of the roof.
You need to wet the brush enough , scrub the RV roof gently and get it rinsed to make sure all cleaner is washed away. One can also try washing the roof with hands but you need to go up there and you surely don’t want to be there when its slippery.
