Yes, many obsess about keeping their roofs spotless. Some (like me) only clean it once a year with blue Dawn and a soft brush. Several years back I found a document from an EDPM manufacturer where they stated it was best to NOT clean roofs unless absolutely necessary, and then only with something like blue Dawn, a soft brush and not to scrub hard. DICOR has another document available that says pretty much the same thing, but they've now got a cleaning product out that they recommend - costs more than blue Dawn though.
