Offering your technical and sales staff training and qualifications to IoR standards will generate customer confidence in your company.   Stockists - to compete on service Stockists are now expected to be able to give technical advice on products. Training for IoR qualifications gives staff the technical knowledge that attracts customers and retains their loyalty by giving them the confidence that they are dealing with well-informed, qualified people.   Designers - to ensure success Those responsible for design and specification need to understand roofing in its every facet and demonstrate that they have a knowledgeable and professional approach.
