Originally the old tiles were staying on and half were being replaced with same tiles, . but I was told they could not get these tiles anywhere to match the exisisting tile. Therefore I was coaxed into having to have all new tiles on the roof. The tiles are very nice apart from the waves that were made putting them on. Then of course the house was stripped, even the new wiring that was put in, when the house was not secure. This in it self is an idiotic way to go about things. No new windows or doors were put in, or even chosen.
