I had hail damage on my roof from a hail storm that my contractor (who does 50% of his work on roofing) pointed confirmed after a big storm. USAA set up an inspection from Alacrity. My inspector seemed rushed from the second he got there and completely blew us off. He said there was no damage when he was leaving, but my contractor tried pointing to the evidence, and his words were (in the most condescending tone) "well, I guess you know more than me and my short 21 years of experience, so why don't you write the report". His report went so far out of its way to claim no hail damage it is ridiculous, but all of his pictures are from the unaffected side of the house. He kept referring to my contractor as 'the painter'. I am disputing his report.
