This company sounds like it's run by morons. I think you should get your money back and hire a different company entirely.

Wow. What a horrible business! I hope you file a complaint against them with the Better Business Bureau, and also consider contacting your local state attorney general's office -- they often get involved in consumer's right cases/issues.

You'd think the crew would know something is up: Wouldn't they see that the roof they're working on is in great condition? Would they have had enough materials on hand to do the whole roof of a house, considering the job was just supposed to be the garage?

And what company (1) plans only one day to put on a new roof (although, you can bet that they didn't tear off your old roof, but merely added another layer to the existing roof) and (2) waits until the very last day to meet the contract deadline? What if it had rained that day?
