About RoMac
SERVING CENTRAL FLORIDA SINCE 1945
​Founded by H. D. “Buck” Robuck and his two brothers after World War II, RoMac Building Supply began life as a single, stand-alone lumber location in Green Cove Springs and was relocated in 1946 to East Main Street in Leesburg, Florida. From its humble beginnings to today, the company has remained a local Florida business owned by the Robuck Family.
Seven decades later, RoMac Building Supply is recognized as one of the largest independent building material dealers in the state of Florida. With locations in Leesburg, Mount Dora, The Villages, Wildwood and Ocala, the company operates 13 businesses which range from retail, contractor supply, distribution, installations, design, to custom manufacturing.
RoMac Building Supply currently operates the only roof and floor truss plant as well as custom door and moulding plant, in Leesburg. These manufacturing plants provide premium custom-building products to clients throughout Central Florida.
The company prides itself in offering the Florida Building Code Approved structural supplies needed by builders, subcontractors, remodelers, and homeowners in Central Florida to construct projects from the foundation to the rooftop. RoMac carries most of the top building supply brands and if we don’t have it, our experienced staff will do everything possible to find or manufacture it.
No other building supply company in Lake or Sumter County has closer ties to the community than RoMac Building Supply, and daily we are investing back into the people we serve. The company has been supplying materials for homes, remodels, and commercial projects for generations of Central Floridians, and your continuous patronage and support for more than 75 years is greatly appreciated by over 500 local associates.
