Our history goes back to 1939 when W. E. Lehman and George B. Roberts bought the Mississippi and Memphis operations of Carey-Reed Company, a company started by Mr. Roberts’ brother in law in 1907.  The new Lehman-Roberts Company located their first asphalt plant and office on Front Street in downtown Memphis.  The headquarters were moved to the current address at 1111 Wilson in 1943.  In 1971, the company became affiliated with Memphis Stone and Gravel Company through common ownership.

Still a family owned business, Patrick Nelson leads as President in our dedication to the manufacturing of quality hot mix asphalt and the superior placement of that pavement.  Anchoring our company's efforts are the core values of stewardship, continuous improvement, humility and relationships. With manufacturing facilities throughout West Tennessee and North Mississippi, Lehman-Roberts Company specializes in construction projects ranging from commercial parking lots to miles of interstate highway paving throughout the Mid-South.
