About Us: ISO 9002 Certification


Throughout its history, LaDuke Roofing and Sheet Metal has always been progressive in the pursuit of excellence. The company was the first roofing company in the country to achieve ISO 9002 Certification (in 1992), and uses a fully integrated software package for its accounting and AutoCAD software for designing site specific details and drawings.


To achieve this certification policies and procedures were installed regarding safety, materials management, office and field procedures, and other responsibilities in order to insure your roof is constructed properly. These are procedures in addition to those required by the roof system manufacturers.


In addition, LaDuke Roofing and Sheet Metal is also a proud member of several trade organizations, including the National Roofers Contractors Association, the Sheet Metal and Air Conditioning Contractors Association and the Southeastern Michigan Roofing Contractors Association.


You can be assured your choice of LaDuke Roofing is one you will be happy with.
