They came out and my roof still leaked. I called for the promised "warranty" and they never sent anyone after 3 weeks woth of phone calls. Two other roofers called, one of whom I had to pay to repair the roof, both acknowledged that the leak was coming from the roof patch from A John Oldja Const. The patch actually had water under it and my roof had waves like a waterbed. The water streaming down from under the patch clearly came from the same spot. Unfortunately, this firm did not seem to me to worry about minor details like a warranty.
