I have a new charcoal colored Galvalume 26-gauge steel roof on my
house. I was wondering if I should expect some fading of the color
over time. Will chalking occur? Do these roofs sometimes need a
professional cleaning? There's a 40-year warenty on the Valspar
What does the warranty cover? Rusting, discoloration, fading, oxidizing,
chalking, peeling? Does the warranty require periodic cleaning, waxing :-) ?
What do the installers say? Do you iron your socks? :-)
It's probably the same or similar finish as used on automobiles. Therefore:
* Fading? Probably not.
* Chalking? No.
* Cleaning? Not as much as a car washing, but, depending on where you live,
stuff from the air will settle.
On the other hand, it's a pretty big chore to wax the roof...
