The International Federation of Roofing Trade is created to study common professional problems and derive knowledge from individual members or the organization as a whole. They exchange documentation and issue statements on common issues. Also, workshops are conducted and they organize a professional competition for young roofers. This is the world’s leading advocacy for the roofing trade.
