Ask the agent if the insurance policy allows third party contractors to roam in the insuring agreements. Is your property insurance up for renewal in the new few months? This could be a case of trespass and a possibility of fraudulent misrepresentation by the contractor which would open the door for a claim against their license and disciplinary action if the mistake is not corrected. Who at the insurer authorized this or is the person a “cowboy?” A drone flying over you residence at a relative low altitude would be a violation of your airspace. Keep us updated as I have been visited by a bunch of roofing contractors lately who want to give me “free” inspections of my roof and are much to insistent about it and they eventually mention insurance. The alarm bells go off and I tell them I was in insurance for30 years (accurate but not necessarily truthful) and they then spout the finer pints of insurance that way too much for a normal roofing contractor to know or be involved with.
