SRS Distribution expanded again today with its announcement that it had acquired National Building Supply Corp., a dealer with locations in Belleville, Roselle, and Dover, N.J.

The firm serves northern and central New Jersey with a 30-employee staff, all of whom plus current owner Tom Lazur who will remain at the company and continue to operate under the National Building Supply name. The company sells siding, roofing, stone veneer, windows, doors, skylights, decking, and railing.

"The addition of National makes us exponentially stronger in New Jersey and also provides us with access to the CertainTeed Vinyl Siding line in the region," SRS President and CEO Dan Tinker said in a statement.

Based in McKinney, Texas, SRS is the No. 9 company on the ProSales 100. It posted sales of $1.92 billion in 2016. This is its third acquisition so far in 2017, and it also has opened seven greenfield locations this year.

SRS now counts 192 locations in 41 states, flying the flags of 20 different companies.
