Welcome to OntarioExt.com

In 1936 my grandfather founded Elmer W. Davis Roofing. Growing up I experienced what makes a successful business and circumstances that challenge a company in accomplishing its mission. As time went on, I had a vision to make my own mark on an industry that had become plagued by cut throat business tactics and a lack of professionalism.
