What they do, is go up on your roof, tell you that you have "hail" damage, and to submit a damage report to your insurance company. The insurance agent comes out, and does a "real" inspection, and tells you that there's no damage to your roof. This happens about 95% of the time, the guy that called you is banking on that other 5%, where he gets a portion of the roof replacement. Does'nt cost you anything, just a hassle....
