Robert Ganter, Jr. established Ganter Roofing Co. in 1978 with the purpose of creating a small roofing installation company.  With his intense work ethic, determination and invested time he started to see major growth in his company.  Contractors, architects and construction managers soon took notice of Ganter Roofing Co. and his business continued to build a solid reputation of quality work.

Watching their small, home-operated business rapidly grow Robert "Bob" and his wife Donna relocated the company to it's company headquarters in Quakertown in 2000. They also renamed the company Robert Ganter Contractors, Inc and have proudly watched it flourish since. The company now employs over 150 knowledgeable men and women of the commercial roofing and sheet metal industry.

Bob's vision and top-notch leadership has caused his business to be one of the top choices among leading general contractors, property managers, roofing consultants and commercial & government property owners today.

Robert Ganter Contractors, Inc. has preserved their world-class reputation by investing in the finest training and equipment available. We are trained in most commercial roof solutions and continue to research and implement the best concepts to ensure the project meets our clients’ expectations.  We provide all labor within our own work force without depending on outside subcontractors.  Our own fleet of trucks, equipment and cranes includes the necessary equipment to accommodate  service, repair and complete installs.
