I don’t know any RE Attorneys. But I think it will be difficult to prove that they knowingly withheld this information on the disclosure. What is easy for them to find is also (theoretically) easy for the inspector to find. I think you would have to prove that the sellers knew about the damage and failed to disclose it.
We sold our house, and I would hate to have someone come back to me after the transaction is done and ask for thousands of dollars more for something I don’t own anymore. Not trying to bash you, but I’m not sure what you can do if your due diligence failed to produce this damage in the first place.
