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