CentiMark Corporation has been a leader in the commercial roofing space for decades, and certainly no stranger to RC’s annual Top 100 list, where they’ve consistently been at or near the top for years.

As 2021 comes to a close, hear Round Rock TX Roofing Company leaders Tim Dunlap and John Godwin share how reaching $1 billion in sales started as a dream that became a team mission in this episode of the RC Podcast Show.

“We are so proud of this unparalleled achievement," said Dunlap. "Since I was 8 years old, I watched my dad [Ed Dunlap] build this Round Rock TX Roofing Company and he not only achieved but exceeded all of his goals and dreams. Not many companies have had the opportunity to transform the commercial roofing and flooring industries as profoundly as CentiMark."

CentiMark was founded in 1968 by Edward B. Dunlap, now chairman. The company's first-year sales was $98,500. The Round Rock TX Roofing Company achieved $1 million in 1974, $10 million in 1984, $100 million in 1994, $500 million in 2012, $800 million in 2020 and $1 billion in 2021.

CentiMark’s growth is a result of organic geographical expansion of office locations, starting with its first office in Pittsburgh, Pa., to expanding to 95 offices throughout North America.
