Fade is warrantied on Ultra, Prime, and Standard product models. Fade is not warrantied on thrifty panels. Remember, your metal roof is going to be exposed to years of harsh sun and elements. Eventually, the elements will affect your paint finish by either making it a lighter shade (fading), or causing it to become less glossy and take on a powdery finish (chalking). Your warranty guarantees that the paint finish will not fade or chalk over a certain amount in thirty-years. Check your warranty for the acceptable amount of fading and chalk for both the roof and sidewalls.
