I didn't even do the roof. It seems to be thicker fiberglass on ours and I had no problems with the roof chalking. Didn't really want the roof to be more slippery either. And many folks have done theirs in sections. The prep work can be grueling so that can take a few days. The actual application is pretty easy, but I still did only one side a day.
Thanks. I wasn't going to use the RMP on the roof. I was really asking if the dirty roof would mess up the cleaned and waxed sides too much when it rained and washed dirt from the roof down on the sides.
