Hairline Scratches Along Seams of Newly Installed Pans

Hi, we are having a new standing seam metal roof installed on our home. The roof is approximately 4,100 square feet. The well-respected contractor is using Firestone Unaclad 24-gauge steel coated with a KYNAR finish. I took a close look at some pans that have been installed and noticed hairline scratches running length-wise up the pans right in the crease where the pan edge was formed. It is not visible from a distance, so I am not overly concerned about cosmetics. I am very worried about rust, however. Interestingly, it looked like the scratch was on one side of the pans I inspected but not on the other side. My UN-educated guess is that the contractor's field pan former is scratching the pans as they are being made. More than half of the roof is now installed and I would estimate that most if not all of the pans have this "issue." Any ideas on what I should do? Thanks in advance!

One thing to realize is that underneath the paint there are layers of primers, and under the primers there is a protective zinc-aluminum (Galvalume) layer. I called Firestone Unaclad and they reccomended that the areas be coated with touch up paint. You can call them at 800-426-7737 to find out where to get it. I would reccomend you talk to your roofer about this. Again a lot of this has depends on the severity of the scratches.

Hi and thanks for the quick reply. We are talking about hundreds of feet or more of hairline scratches up and down the pan seam creases. I would be concerned that adding that amount of touch-up paint could create cosmetic issues (i.e., mismatched colors, uneven surfaces, bubbled areas, etc.) that do not currently exist. Also, I am concerned that the roofer might balk at a request to apply such a large amount of touch-up paint because of the time and expense involved. I will try to take a picture of what I am talking about this evening and post it here. Thanks again.

A picture would be great. It would kind of worry me that the roofer ran out and put on that much material if the scratches were serious.

Attached is a picture I just took of an installed pan. The thin white line running horizontally across the center of the picture is what I have been describing as a "hairline scratch." Comparable markings exist on at least one side of just about every installed pan I have examined. My main concern is the potential for rust down the road. Any comments would be greatly appreciated. Thanks!

This looks like a scratch which was coming from their machine. It definitely is not optimal in terms of the quality you probably were seeking.
