Judging by his irriational reaction to your concerns, I'm guessing that there are nuances to this situation that we will not learn by hearing only your side of the story. I fully understand the contractor's refusal to 'work with' you given what I am guessing is your combative attitude. He probably figures he's going to get screwed wether he fixes it or not...so why fix it? I'm also guessing that the other 1/2 of the "we" that hired the roofer doesn't feel the same way you do. Admittedly, I'm taking the liberty of reading between the lines of your post in that regard.gotjacked? said:Says he will not pay his suppliers or his workers. That he will pay no one and that he will lien our property. I wonder what he did with the $4500 we paid him?
It sounds like you got an appropriately spec'd and properly installed roof system. It also sounds like you didn't have a proper roof on the patio before -given that all the roofing materials were the same color and given what seemed to be your infamiliarity with the bitumen product that was installed. So I don't think anyone's trying to 'pull something over' on you by using a product they otherwise wouldn't.
