What is the Roof and Facade Security Seal of Approval?

The basis for the seal of approval is provided by the Metal Facades and Roofs Quality Guideline. The Quality Guideline was developed by manufacturers and specialist contractors of metal roof and wall systems and is continuously updated. The Quality Guideline describes the requirements for roof and wall systems and how they should be constructed. Components of this quality mark include professional competence, safety, quality and environment. An approved company can be recognized by the Dak- en Gevelborg logo.
