Metal roofs for SFHs are mostly beneficial in wildland / forest areas where there are wildfires. Shingles will burn (they're made of petroleum products), while a metal roof will resist far far far longer. However this only makes sense if the rest of the structure is also just as fire resistant. Metal roofs will also last a lot longer. Their color may not, but the roof itself, as long as it was installed properly (major component here), will outlast asphalt by decades.
