Limbach's Company History.


Frank Limbach

Frank Limbach, a talented metal craftsman, creates a one-person sheet metal roofing company in Pittsburgh, PA, with little but his own integrity and skill. The fledgling Frank Limbach Company manages to survive and grow by performing architectural, roofing, and ventilation sheet metal work for residential, industrial, and institutional customers.


The Frank Limbach Company is one of only a handful of entrepreneurial companies to weather the Great Depression.
