Hail Damage does happen!
Look at that pretty crater!
I've been inspecting roofs for 12 years. Before Covid, hail bruises counted. Now, most carriers wouldn't know hail if it hit them in the face. Or, they choose to use a 3rd party inspection company that acts as they have special glasses on that makes things look pristine.
Random patterns
Hail storms aren't artists. They won't make a pattern. There will be random "spatter" or bruises throughout the roof.
Hail & blistering are not the same!
Hail = insurance owes. Blistering = wear and tear and they don't.
Most of the guys running around knocking doors has no clue 1 vs the other. Or they do and choose to advise you start the claim anyways. When in doubt, call someone for a 2nd opinion!
