You are probably 1" to short, doesn't that piss you off. You probably have a 5" gutter system instead of a 6" one. And they say size doesn't matter, that 1 extra inch makes a world of difference!

While cleaning out your gutters don't forget the downspouts & drainpipes. If they get clogged & a freeze hit they cause a back up all the way to the gutters & the metal pipes will bust under the pressure. PVC doesn't look as nice but schedule 40 PVC (not the thin PVC) will hold up better than metal & won't dent either (but they will shatter if hit hard with a baseball bat when frozen).
