I have forgotten, and can't seem to remember the warranty on the rubber roof. I also can't remember if this needs treatment, and if so how often and what to use? I'm interested in all comments, but mainly manufacturers warranty.
Rubber roofs and TPO type roofs usually have a warranty around 10 years pro rated.
That will vary on manufacturer.
You are going to need to know who manufactured YOUR roof.
Rubber roofs need cleaning and treatment.
TPO roofs just need periodic cleaning.
