Layers who handle hail damage claims will frequently run into the situation where an adjuster admits there is hail damage on a roof but that the damage is old or there is old damage and new damage to the roof. The question becomes, what is the best course of action in getting a full recovery. The answer is to file claims / sue both insurance carriers. The U.S. District Court, Western District of Texas, Austin Division had this issue in a recent case. The style of the case is, Evridges, Inc. v. The Travelers LLoyds Insurance Company.
In this case, Evridges filed suit against Travelers for hail damage to its property. When evidence that some of the damage was from another storm when another insurance company and policy were in force, Evridges sought to have Travelers added to the lawsuit. This insurer is Landmark American Insurance Company.
Travelers opposed the joining of Landmark, arguing to the court that the joinder was improper under Federal Rule 20(a) because the claims against Landmark do not arise from the same transactions or occurrences as the claims against asserted against Travelers, and since the claims against Landmark do not present common questions of law or fact as the claim against Travelers, that the joinder is improper.
