I had this company to do the roof on our build. They were dreadful. Tiles were misaligned. Fitted damaged tiles. Even stuck a broken tile together with sealant instead of replacing it. End verges didn't line up. Tiles around windows we not cut properly (some not cut at all, and left just sitting on the window frame). Ridge tile lengths all over the place. Ridge tiles not fitted properly, loose. Having to have the roof redone by a competent tiler. Regarding response from Ridge Roofing Services (see below), I gave them the details they asked for and, or surprise, heard nothing back.
