In our fifth decade in the roofing industry, we take great pride in the people and professionalism that drive CentiMark to new levels of success and excellence in roofing and flooring.

Raising the Roof and Kicking Off Our 50th Anniversary Celebration!


April 19, 2018 is a monumental day at CentiMark Corporation, Canonsburg, PA. This date marks the 50th anniversary that Edward B. Dunlap founded a small janitorial supply company, Northern Chemical Company, that eventually became CentiMark - the largest commercial roofing and flooring contractor in North America.

While roofing and flooring is our business, giving back to the community has always been our commitment. 

To celebrate this milestone and to recognize 50 years of philanthropy to the community by The Dunlap Family and CentiMark Corporation, we are asking you to say “thank you” to Ed Dunlap and CentiMark.
Donations can be made to either Make-A-Wish or St. Vincent de Paul Scholarship Fund.
