This company installed a roof on my residence in the fall of 2013 and it has continually leaked over my fireplace causing sheetrock damage on two occasions. They recommended that I get a Waterproofing Company out because it was definitely the grout in the chimney and the waterproofers proclaimed my chimney grout to be perfectly intact. I'm having to spend $550 to get it sealed and guaranteed by the waterproofer. Mind you I am not sealing the grout I am having to seal the roofer flashing that he installed around my chimney. During the first call that I made to him the initial time, the first thing that came out of his mouth was that I was out of warranty.
