My Alpha roof recommends Spic n Span, basically no harsh cleaners & no sealers required.
I use Simple Green concentrate mixed a bit on the strong side in a gallon sprayer, saturate the roof, wait 15-20 minutes, scrub with a medium bristle brush with a 50/50 mix of Turtle Wax & Mcqiures Gold carwash soap, & rinse thoroughly.
