x2 on the Roof Cleaner and Roof Conditioner. You need to know for sure what type of roof you have before you start. Our HTT and now TT are under a covered Rockyport, so they did/do stay cleaner. When DH installed the vent covers a few weeks ago he said that the roof could stand a cleaning, but as much as he and his high-tech hip enjoy going up the ladder and onto the roof, I'd bet it'll wait.
Re the ladder....ours is very usable and has a sticker that gives weight limits. If you're not sure, check with the manufacturer, but I'd bet you can go ahead. DH did say that it was a LOT easier than going up the step ladder and then crawling onto the roof.
