Randy,
While it's probably not the best idea I have pressure washed mine with a cheap Harbor Freight electric pressure washer. It doesn't have anywhere near the power of my Honda Gas pressure. It did remove most of the dirt, but I still needed to use a brush mounted to a handle to scrub the toughest spots. I also kept the tip at least 6 inches from the roof.
My gas unit would certainly do damage to the roof. This electric unit works well on painted surfaces , cars, and has never damaged anything.
You may end up with one that has too much power so proceed with caution.
