20+ year adjuster here… just a few thoughts…
First, did a staff adjuster (employed by the carrier) look at the damage, or did an 1099 independent adjuster or a third party (like SeekNow or Hancock Claims Consultants) do it for them? I'm asking because it can really affect how credible the inspection results are. I specifically work in QA and review files day, and the work product that is produced by the different adjuster types can be substantially different in quality. You can get anything from a seasoned veteran to a guy that got hired with no experience and has no clue. Major issue with the industry ( story for another day ).
Also, do you have a cosmetic endorsement on your policy? This can be important when figuring out if you're covered. Look up functional damage vs cosmetic damage if you are interested to know more.
If you received a denial letter, it should specifically list out the reason why it was denied with any applicable policy language.
When you say "denied a reinspection," did your roofer send in more photos/evidence to back up your claim? Example: photos of dented vents, flashing, gutters/downspouts, hail spatter on your fence, etc.? Usually, an adjuster won't agree to a reinspection unless they have some extra proof. Putting in a bit more effort to show why you need a reinspection can really help. Again, if the field adjuster report sucked , this could be a major reason what the desk adjuster is refusing to allow for a reinspection. No disrespect to roofers, but it can be the same story with experience, etc. Not all roofers/door knockers know how to navigate the claim red tape. They would rather move on from problematic claims and choose to work on the slam dunk easy commission sale rather than sorting out issues with a carrier. Remember, they only get paid when you get paid.
Furthermore, most insurance companies will hire an engineer to look at the damage at their expense and give a professional opinion before denying a claim if they get more evidence after the initial inspection. It's more cost-effective and reliable before going to appraisal or dealing with PA's & Attorney representation.
Lastly, if a PA is charging you upfront, it might be a good idea to stop working with them. They're on the same team as you, and they're getting a cut of the insurance settlement based on the contract percentage you agreed on. Appraisal is different. If you're skipping to that step, then yes, you will need to pay the appraisal fee & the cost for an umpire. Hope this helps
