Ross Roof Group has been involved in roofing over 5 generations since 1942. It is an innovative and dynamic manufacturer and supplier of stone-coated steel roofing tiles. Its stone-coated and satin-finish roofing systems incorporate cutting-edge Zincalume protective steel, which gives the tiles a significantly longer service life than typical galvanised tiles. RRG has two major brands – Metrotile Roofing Systems and Tilcor Roofing Systems. Both Metrotile & Tilcor offer a wide range of tiles that are architecturally designed and engineered to the highest quality and for the roughest environments. Products are based on the principle of utilising only the best raw materials. Natural New Zealand stone granules are the foundation of long term durability, stability and colour retention on all its textured roofs. The roofs are installed in over 80 countries in the most extreme weather conditions — from the snowy regions of Europe to the harsh temperatures in Africa to the hurricane prone countries of the Caribbean.
