They do this when there has been a significant impact to a large area of homes. Usually within a radius of a mile or two. Personally, as a project manager, I don’t like them because what is seen on video/picture is different than what your eyes can see, but as long as the collateral damage (downspouts, siding, fascia wraps, etc.) is visible, it can be mostly a good experience.
We had one the other day that the insurance told us, the contractor, to take photos around all elevations and roof, and document damage and send to them. We did, and then they saw how significant it was and said essentially we don’t believe you and now are sending out an adjuster. Anything to make the process more difficult!
Honestly, if anyone needs help with this stuff or has questions, I don’t really care about using me and my company, I just want to make sure people are getting taken care if. This can be a daunting experience and I hate how insurance can sometimes take advantage of not knowing. Feel free to DM me anytime.
