Was there a Seller Disclosure available when you purchased the home? If yes, what did it say regarding the roof and any possible leaks?
What exactly did the home inspection report say regarding these areas?

Then you could hire a cracker Lawyer to sue the Seller; maybe get triple damages and pain and suffering!
From your description, this problem has been on-going, with the mold and the wood damage and all: They must have know. Of course, that means that your Inspector didn't find it either:
You could include your own inspector in the lawsuit.
Then, if there is a bucket where the drain line should have gone outside to empty, that is not the correct way to drain the condensate line. That should have been disclosed to you by the seller, especially because it can require being emptied. You could have legal recourse there for the amount of damage it has caused because the seller would have been aware of it.
If there is a defect (assuming that a defect exists) that is known to the seller, that seller is required to disclose that fact to a buyer. Not doing so make the seller liable for correction of the defect and damages even after the sale. Seek legal counsel for that issue. Your real estate broker might be able to assist by asking the seller for cooperation. If the real estate broker knew of the defect, then that broker was also required to disclose that to you. If you bought a for-sale-by-owner, then you would need to contact the seller directly.
