Your roof is a TPO membrane.
I have used eternabond (or similar micro-seal tape) to repair rips on one of my past RVs. Where did that tree limb come from?
Follow the instructions for cleaning and prep. I also caulked the edges of the tape otherwise they turn-up and look ugly with time (I did not caulk the edges the first time).
Just curious - how old are the rips? Did you find evidence of any leaks?
Can you post pics?
