Will a Metal Roof Rust?

Today’s metal roofing is a far cry from the old barns you might see off the side of a road.  Now, the metal preparation and finishing is more like that of the automotive industry! Advanced galvanic treatments to the base metal prevent rust for decades. MPI’s metal panels are pre-painted with baked-on primers and a heat-cured factory finish.  New multilayer paint technologies allow for finish warranties upwards to 40 years.
