About Us
Our History
We are a full service roofing and sheet metal fabrication company that was established in 1970. The company was started by Lionel Smith, a young sheet metal mechanic with over a decade of experience looking to make his mark on the city he loved. For forty years Mr. Smith led his company through its many growing phases including metal fabrication, steel building erections, shingle and slate installation, and gutter & roof repairs. Today, we are a full service sheet metal roofing contractor with the experience and staffing to handle the largest installations for nearly every application. Ushering in a new generation into the business, Mr. Smith brought in his son, Lonnie Smith to his business. In nearly thirty years of learning and nurturing the company with his father's supervision, Lonnie and his father have brought the company through everything from hail storms to hurricanes.
