Karl Calkin Sr. My Name is Karl D. Calkin Sr. and I was born in New Jersey. Following my education, I went to work for my father Harry Calkin. He was a painting, sandblasting and roofing contractor with 5 children and a great wife. That was when my real education started. He was a fair but a stern man who taught me that his company was a service business and without happy, satisfied customers that believed and trusted him he would have no business at all. He taught me a base of knowledge that to this day is my business belief. 1. Know your business. 2. Don't take short cuts that jeopardize the final product. 3. Tell the truth. 4. Your reputation is more important than the money you make. 5. Always finish what you start. I have been a roofer for over 38 years. Because of that, I know what products work well as well as the manufacturers that have the same beliefs that I do. I have been at the for front of the industry since the early1980s. My company is named Integrity for a reason. People that come to know me say that my integrity comes across loud and clear. I sold my company in New Jersey in the early 2000s (Integrity Roofing Inc.) and to this day the company is doing well . I started Integrity Roofing and Waterproofing Inc. in Florida in 2008.
