This sounds like you're in a wind trap area. I've seen this a few times! Either the tiles in the area affected will need to be nails in with a good quality nail or glue to prevent the same happening again. I would recommend posting the job on here and asking for a roof report from the roofing company and providing that to the insurance/ home builders as you then have something to back up your claims. Hope this helps. Lewis
