Allied Building Products announced today it purchased the assets of United Products Corp., a roofing and siding distributor with 15 branches in five Upper Midwest states.

Minneapolis-based United Products has grown since 1975 to count seven branches in Minnesota, three in Wisconsin, three in North Dakota, and one each in South Dakota and Nebraska. "The United Team, aka Eagle Team, is extremely pleased to be joining forces with Allied," United said in a statement."The two organizations share a common goal of doing whatever it takes to exceed the customer's expectations at every opportunity. We look forward to continuing to support our customers' needs as part of the Allied team."

Today's news follows last month's announcement that Allied had acquired eight facilities in a trio of deals: The Smyrna, Ga., branch of American Wholesale, a residential siding supplier; Pacific Source, a building materials distributor based in Snohomish, Wash., that serves Hawaii from branches on Maui, Kauai, and the Big Island of Hawaii; and Ivan Supply Co., a roofing and siding distributor with four branches in the city of Philadelphia.

Allied is a division of Oldcastle Inc., the North American holding company for Ireland's CRH Plc. It ranks fourth in this year's ProSales 100, having reported total revenue in 2010 of $1.64 billion, 95% of it to professional builders and remodelers. Allied also reported having 178 facilities and 3,100 employees as of the start of this year.

In today's announcement, Allied described itself as having "c. $1.7 billion" in annual revenues and operations in 30 states. There was no immediate word on whether Allied planned to keep all the United branches.
