Not sure about you but if the tear is what cause the roof leak and then rot the wood wouldnt you want to replace the rubber membrane instead of keeping it and trying to piece it back together. just my .02
I know the tape can pull the rubber together but whats not to say you are driving down the road and the tape pulls off - you will be back to square one with a wet and possibly rotted roof again.
I would seal the edge's with Dicor Lap Sealant - like stated
