Metal is normal here
On a Folsom lot, metal on the house or the shop is often the existing system, not a sales upgrade. We repair or replace the system that is there when the deck and the fasteners say so. Exposed-fastener panels fail at the screws and the edge. Standing seam is a different detail. We name which one you have.
A small asphalt roof in the village is still an asphalt scope. We do not convert it to metal because the neighbor has metal.
