We paid them almost $5K to put a treatment on our roof, that was supposed to make our older roof last another 20 years. They did not do what their contract said they would do. Inspection shows there is almost no product on our roof, after just 3 years. They will assume no blame and want to blame the product maker. They have given us the run around for 6 months. Do you think they sent out one of their roofers to even look at the problem? Nope, they waited till we filed Small Claims and then sent their lawyers after us.
