Most standing seam metal roofs have a factory finish with clearcoat - warranted. Lots of color choices.

Goes for some of the 'copper' ones as well. The ones that remain copper color. The ones that turn 'green' have a real unprotected copper coating on them... or are really sheet copper roofing ($$$$).

Very, very common in snow areas.

Lightning is not a issue any more than with other roofs.

If your cell works in your metal car, it'll work with a metal roof.
