Don't lose sight of the forest for the trees.
Again, I'm not an attorney. But I don't see how a manufacturer has the right to develop a product that intentionally damages the property of others. Nor do I see how your neighbor has the right to intentionally damage your property.
You need to fix the problem with your neighbor first. Even if you can get the insurance company to repair it, they are only going to repair it so many times before they refuse to renew your policy or insist on an exclusion for this.
I have a recorded conversation with the manufacturer where they tell me they are aware the product does this but it's not their problem.
I realize I need to fix the problem with the neighbors first. I have an attorney and am working on it. I only asked the insurance company what my coverage is. I never put in a claim first because I knew the neighbors had to fix their house first and second because I didn't know if a house that has a death ray pointed at it can be insured.
