have friend with cedar siding, at 20 years home needs resided, birds
pecked holes in siding looks bad, maintence costly.

metal aluminimum or steel will hurt radio tv and espically cell phone
reception a lot. have friend who must go outside to use cell phone.

vinyl siding looks good lasts just about forever, requires no
maintence at all. doesnt dent either.

composites might be ok but as you get older no maintence becomes more
important.
