Looks like the edge blew right where it seems together? I don't have experience with fixing that, but I don't see why you couldn't work your way from the good side to the bad side and slowly form it back together....
And don't use JB weld, use a waterproof epoxy when "glueing" it all back together.
I have a good feeling with some time, you can get that edge back to where it needs to be and actually fix this problem
