I work on the shipping dock at a roofing plant. We're already having trouble getting trucks as FEMA has grabbed a bunch of trucks and is paying them to sit until material needs to head to Texas flood areas. The few trucks we can get have troubles getting the loads down there. We've already had one stolen. The trailer was found in a field with part of the load missing. If you're in Texas and can get roofing really cheap, you may not get a warranty on the stolen material.
