I clean our once maybe twice a year.
I clean it when I'm dewinterizing it and then maybe once during the season or when I'm winterizing it.
When I clean it I also check all the seals on sides and around vents, etc. to make sure they're ok.
I use either a roof cleaner or mild water-soap mixture. I also use a bleach-water mixture sometimes to try to clean the spots.
Iím sure youíre going to get a lot of variations on how and the number of times people clean their roofs.
A lot depends on your geographical location, where you camp, where the trailer is stored, etc. with how dirty your roof gets and the amount of times you should clean it.
