ABC Supply, which ranked No. 1 in the 2014 ProSales 100, announced on July 2 that it has acquired Dealers Service & Supply, which distributes roofing, siding, windows, and doors from locations in St. Louis, the St. Louis suburb of Kirkwood, Mo., and Belleville, Ill.

“We are very happy to welcome the members of the Dealers Service & Supply team to our ABC family,” said Keith Rozolis, president and CEO of ABC Supply. “With these new locations, we will be better able to serve the contractors of the St. Louis area.” ABC Supply operates six other branches in the St. Louis metro area.

All of the employees at Dealers Service & Supply, including former owner Robert Vatterott, will remain with the company after it takes the ABC Supply name.

“Contractors will be getting the same great service from the same people they’ve been dealing with for years when they visit these locations,” Rozolis said. “We look forward to working with Robert and his team to service our new customers.
