100 years history of building scientist and commercial roofing contractors.

J. Smith Group LLC was established (est. 1984) in Nashville, TN from its original form Home Roofing Co Inc. (HoRoCo) 4th Generation Roofing Company (est. 1948) Inc. Originally, our focus was primarily concentrated on the science and application of commercial roofing & Sheet Metal Contractors from built up roofs to single ply systems. In the process of our work, we increasingly encountered building failures resulting from components other than roofing. Over time and thousands of Roofs later our investigations allowed us to evaluate products and construction techniques and determine what worked and what didn’t. As a result of this experience, we have become knowledgeable in all aspects of the building facilities envelope. This allows us to provide complete facilities envelope services in house without the need for outside services. Because J. Smith Group is licensed as a Roofing Exterior facilities Consultants Firm, we are able to provide design/testing services (including necessary calculations and Architectural and Engineering judgments) that may not be provided in house by unlicensed consultants.
