I am going to have a 24 gauge Kynar standing seam metal roof installed on my new home. Some articles talk of the panel lenghts being custom cut either at the plant or on site with portable fabricating equiptment. My builder plans on having his roofers cut the panel lenths on site with a crimping type shear. I am concerned with the quality of the cut and possible rusting. Any comments? Also, do the cut edges need to be painted?

Panels should be cut with a shearing action. Even factory formed panels usually need to be cut on the jobsite. In most cases, cut edges are not painted. It would not be a bad idea though.

Can you offer any more guidelines about coating the edges of cut roof panels? I understand that shearing (rather than cutting with an abrasive blade) is recommended because it eliminates hot metal shavings that can burn through paint coatings and cause rust. But do any metal panel manufacturers (or the MRA) specifically recommend treating cut edges. I agree that it seems like a good idea, but if it's actually unnecessary from the point of view of the manufacturers, it would be helpful to know that.

I do not know anyone who recommends it as part of standard procedure. If it is done, it would just be the matter of rigging some method (brush or roller or dip tray) to apply a quality rust inhibiting paint.
