The history of Tilcor's products demonstrates that fading is not a problem. Tilcor uses either naturally colored or ceramic coated stone granules on their tiles. The natural stone cannot fade and the ceramic coated stone is manufactured with the highest quality pigments and fired at temperatures above 700 deg Celsius. Over time, a slight change in color may occur due to settling of airborne contaminants. However periodic rain or washing the roof with a garden hose will keep the roof looking new.
