We hired OAM four years ago to install a new roof and gutters. Since installation our roof has leaked twice causing damage to our living room ceiling both times. I have made several phone calls to OAM and they refuse to call me back. I am so very dissapointed that they do not stand behind their work. I hired them because they were very polite and appeared to have several years of experience. The bottom line is this, don't let this company charm you into hiring them to install a new roof, you will regret it.
