I boondock all the time. I go in some tough places. I've "scratched" or "torn" my membrane in several places....all looking like your damage. Frankly, such damage may pose a challenge for warranty coverage...it's usually self inflicted.
Go the warranty route if you wish.
Should you choose to effect a repair, I used Dicor self leveling sealant to patch up the damage.
https://www.amazon.com/Dicor-501LSW-.../dp/B00G6KGPFM It took a couple minutes, $12 for the tube of Dicor, and the problem is solved... until next time I drag my rig down an ATV trail deep into the woods.
If the roof actually failed due to a factory defect, I'd pursue warranty repair, because the real problem is much larger than the visible damage. But I'm not eager to lose the use of my rig for an extended period to get a new membrane when there's nothing wrong with the one I have.
