Travel Trailer Rubber Roof Blew Off

I can’t figure out how to reply to a specific post but I’m not certain if they got it from a show or not, it seems over the past few years these things are being made more and more carelessly with there record breaking sales. What’s crazy is we just had our mechanic up on the roof to reseal everything before we started this season a month ago, and we double checked all of his work and everything was sealed and fine looking before we left, he even notices places where they missed putting screws in at the factory in the front and fixed that.
