CentiMark's History

“While CentiMark has many assets, our greatest strengths have always been and will continue to be the dedication and hard work of our associates. Together, we work hard and work smart.”

- Edward B. Dunlap, Chairman & CEO, CentiMark

From a small upstart...

Edward B. Dunlap started D&B Laboratories in 1967 as a part-time industrial cleaning products business in the basement of his home. In 1968, with $1,000 seed money from D&B Laboratories and one associate, Dunlap started Northern Chemical Company. This upstart building maintenance products and services business produced first year sales of $98,500.

In response to customer needs, Northern Chemical Company became involved in roofing and flooring maintenance. In the 1970s, the oil crisis negatively impacted the built-up roofing market that was dependent on crude oil for asphalt. The quality of asphalt decreased as oil companies were pressed to extract as much oil from crude as possible. The price of asphalt increased, thus resulting in higher roofing prices.

Concerned about the quality of bituminous materials used in built-up tar and asphalt roofs, CentiMark began marketing and installing single-ply rubber (EPDM) roof systems. The newly developed EPDM polymer was both durable and waterproof. It was a cost-effective solution to the increasing costs associated with built-up roofing. In the late 1970s and early 1980s, EPDM was one of the fastest growing roofing products and accounted for almost 40% of new and replacement roofs on commercial and industrial properties. For years, CentiMark was known as the rubber roofing company.


...To a nationwide footprint

The company, with corporate headquarters in Pittsburgh, PA, grew through geographical expansion, diversification of product lines and an aggressive National Accounts Program. In 1987, the corporate name was officially changed to CentiMark Corporation. "Centi" refers to the 1987 goal of achieving $100 million in revenue (achieved in 1994). "Mark" recognizes the company's unique contributions to the roofing industry - the first National Account program in roofing and flooring, Single Source warranties on workmanship and materials and nationwide geographical expansion through organic growth, not acquisition.



Each decade brought a new milestone: revenue of $1 million in 1974; $10 million in 1984; $100 million in 1994, $300 million in 2004, $400 million in 2009, $500 million in 2012 and $600 million in 2015. 

In 1991, CentiMark became the first and only roofing contractor to be rated 4A1 by Dun & Bradstreet based on a strong credit appraisal and net worth. By 2000, the rating increased to 5A1, the highest level by Dun & Bradstreet. CentiMark continues to be peerless in the commercial roofing industry regarding the 5A1 Dun & Bradstreet rating. 

In January 2003, Timothy M. Dunlap was appointed President and Chief Operating Officer of CentiMark. Edward B. Dunlap, Founder of CentiMark, continues to serve as Chairman and Chief Executive Officer. Today, CentiMark is the unparalleled leader in the commercial roofing and flooring industry throughout the United States and Canada.
