Had an almost identical situation with a customer once on a modified bitumen roof. he didn't attack my insurance/bond though.
Talk to the people who sold you the bond and ask what your recourse is. Often times insurance companies will award payments just to make problems go away. For them $12k isn't alot of money and would cost more to fight. They'll get it back from you anyways in the form of premiums. Contact your insurance broker, the one who sold you the bond, and if he can't help it's time to find a new broker because he's worthless.
Hopefully some others have some insight. Sorry. Good luck.
