Metal siding is a traditional option but with a newer stylish look. Metal siding is maintenance free and extremely durable. Metal siding also does not absorb moisture or promote the growth of mold or fungus, both of which can destroy a home’s framing and can pose health hazards to the occupants. Another advantage to metal siding is its fire resistance. Even if a home is struck by lightning, a metal-clad dwelling is almost impervious to fire.
