Is a WANAEL ROOF System warranted?
The best in the Asian industry. NUORAN Roofing Systems carry a 50-year warranty including 160 mph windproof and hail penetration for any size hail and manufacturing defects - including excessive granule loss. 

Does the color fade?
Though sized more precisely, WANAEL uses the same stone granules used by asphalt shingle manufacturers for over 50 years, so history demonstrates that fading is not a problem. 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.
