Assuming that your Mother has Homeowners Insurance , contact her company and make a claim. They will assist you in finding out if the neighbor is insured. There is a large data base available in the Insurance industry that they can utilize. The two companies can resolve this for you -- if there are two companies! Should your Mother have the only insurance , her company will be liable. Be certain they consider the damage to the roof - from the tree AND from the efforts to remove it, and also the water damage inside from the leaks .The fence problem is also related.

From the information given, it looks to me like under the Law your neighbor is liable for the roof damage either from the negligence in not properly maintaining or trimming his tree limbs and/or from negligently trimmings the branches likely causing more damage. I deal with this situation all the time and have file some lawsuits to get funds for damages as well. If he has no assets, money or insurance, then all you can do is go to Court and get a Judgment, but the may be able to avoid that in bankruptcy. That is why these lawyers are saying make a claim on your mom's homeowner's insurance, then your Mom's homeowner insurance company will pay and try to get their money back from the neighbor. We can help with that as well..
Finally, if you or your Mom dont want to deal with the neighbor, the quickest solution is to have an Attorney send him a notice of claim demand letter asking him to notify his insurance carrier if any and deal only with the Lawyer. I can do that in a day for a very low flat fee for just the letter.
