I'm just finishing the first year of owning a Micro Minnie 2108DS. It has been wonderful and virtually trouble free. Since I'm at the one year point I need to perform roof maintenance. I believe the roof is TPO. I've cleaned and inspected the roof but I'm unsure if I need to put conditioner on the roof. There seems to be divided views on using a conditioner on a TPO roof after a cleaning. I'd appreciate any tips on roof maintenance.
