Our History

In December of 2021, we became the first commercial roofing and flooring contractor to achieve one billion dollars in sales for a single year - the dream our founder always had.

CentiMark Corporation's Leadership

Tim Dunlap - CEO of CentiMark

Timothy M. Dunlap

President & CEO

Tim Dunlap has been the President of CentiMark since January 1, 2003 and the CEO of CentiMark since February 15, 2021. Tim's youth and professional life paralleled the growth of CentiMark after his Dad founded the company in 1968 when he was eight years old. A young Tim Dunlap spent every weekend at his Dad's side being educated in the business. He was paid $.25 an hour to sweep the warehouse, label cans for flooring products and, eventually, go on sales calls with his Dad. Father and son would have Saturday lunches together and discuss all the trials and tribulations of starting and growing a business.

Two weeks after high school graduation, Tim began working on the roofing and flooring crews. His professional development in the business of CentiMark continued as an Estimator, Technical Representative, Sales Representative, Sales Manager, Branch Manager, Regional Manager and Group Director before his appointment to CentiMark's President and COO on January 1, 2003.

In the growth and development of CentiMark, Tim's "Mark" has been bolstering sales and marketing initiatives, utilizing technology to benefit customers, vendors and associates, enhancing customer service initiatives, using separate crews for production and roof service repairs, creating comprehensive National Accounts Programs and expanding QuestMark to include DiamondQuest floor systems and online product sales. Tim oversaw the steady growth of the company from $247.5 million in revenue in 2002 to a record-breaking $800 million in revenue in 2020. That's more than four times the revenue in a 19-year period, despite the challenges of the recession in 2008 and the pandemic in 2020/2021. On December 21, 2021, CentiMark became the first billion-dollar commercial roofing and flooring company with sales exceeding one billion dollars.

CentiMark Corporation's Founder

Late Ed Dunlap - Founder of CentiMark

Ed Dunlap

CentiMark Founder and Chairman, died on July 23, 2022 and left a legacy of hard work, success and excellence.

In 1968, Ed Dunlap started a janitorial supply business in the basement of his home. With $1,000 and one associate, he started the business that would become CentiMark. He soon realized the business need was for contractor services to repair and/or replace roofs and floors in addition to the products for roofing and flooring repair and cleaning. CentiMark became the official name of the growing business in 1987.

As an entrepreneur, Ed Dunlap embraced new ideas to develop and grow the business. His willingness to utilize a new roofing membrane material called EPDM (rubber) on the roofs in the 1970s became a game changer for his growing company.

Other initiatives in the 1970s and 1980s became the "Mark" in CentiMark and had a significant impact in the roofing industry. Ed Dunlap started the first National Accounts program in the construction industry, established a toll free 800 number for one point of contact for all customer phone calls, created a Single Source warranty for workmanship and materials and expanded office locations throughout North America.

First year 1968 revenue for the new company was $98,500. Each decade brought a new financial milestone: revenue of $1 million in 1974; $10 million in 1984; $100 million in 1994, $300 million in 2004, $500 million in 2012, $800 million in 2020. Sales revenue in December 2021 was over one billion dollars.

Family Business

The late Edward B. Dunlap (9/18/1938 - 7/23/2022) and CentiMark have achieved unbridled success along with amazing challenges in the growth and development of the business. Today, with Tim Dunlap at the helm of the business as President & CEO, CentiMark remains the largest commercial roofing and flooring company in North America. Tim Dunlap and his 3,500 dedicated CentiMark associates work to meet the needs of our customers. We are proud to have achieved one billion dollars in sales - the first for a commercial roofing and flooring contractor.
