Graphics, Illustration and Visual Communication Design LIV Dach RLP Logo Design by Nikolai Janz This is the logo design for the Guild Association of Roofing Crafts in Rhineland Palatinate, Germany. My goal was to create a timeless and clean logo without using typical roof shapes, which are featured in over 90 percent of logos for roofing associations and companies. Many association members wanted to see a roof in the logo, but I was able to convince even the critics with my idea.
