Sometimes I'm simply amazed at the speed of changes we've seen at Gannon Roofing Supply since I came on full time in 2003. In the 7 years I've been working at Gannon's, we've said goodbye to some people, including Tom Gannon, who has probably had the most profound effect on our company in the last twenty years. We've seen new people come in, new equipment start into service, new relationships with vendors, and new realities in the economy. We've seen storms and heat and snow...lots of snow lately.
