Does the color fade?

Though size more precisely, Sangobuild use the same granules used by asphalt shingle manufacturer for over 50 years, So history demonstrates that fading is not a problem. Over time, a slight change in color might occur due to sitting of airborne contaminants.

How do the granules stay bonded to the steel?

Specially graded 'non-oiled' natural granite stone chips, produced by CL Rock company are used for all Sangobuild stone coated roof tile.
