Beacon Roofing Supply, No. 4 on the ProSales 100, announced today it acquired Lowry’s Specialty Distribution, a distributor of waterproofing, sealants, and air barriers with 11 branches in four states.

Lowry’s, based in Los Angeles, has seven branches in California, two in Hawaii, and one each in Utah and Arizona. It will continue to operate under the leadership of President Craig Dirickson as Lowry’s, Systems Waterproofing Supply, and Can-Do Supply.

Beacon CEO and President Paul Isabella said in a statement, “Lowry’s is a great addition to Beacon and significantly strengthens our existing waterproofing and related complementary products business in the western United States, including our first entry into the Hawaii market. Waterproofing and related products comprise a huge and growing market and present tremendous sales opportunities for Beacon, both to Lowry’s existing customers and through cross-selling to our core roofing contractor base. The entire Lowry’s, SWS and Can-Do teams will be key players in our continued growth in this important product market and we are thrilled to have them as part of Beacon.”

With the addition of Lowry’s, Beacon now has over 380 locations across North America. The Herndon, Va.-based firm posted $2.5 billion in sales last year.
