And using seamless aluminum gutters eliminates the rusting problem,
and makes it pretty simple to eliminate low spots too.
The guy that put mine up "levelled" it with a laser. Just aimed the
laser from the high point to the low point and made sure the trough
followed the beam

Thats if you want to pay big bucks to have someone install seamless. I
put up my own and it has seams. The laser level is a good idea though.

As far as aluminum, it will expand much faster than steel from ice. One
thing evryone seems to ignore is that it's not just a small puddle, it's
a spot that attracts debris, and that freezes and adds more ice and then
there are ice dams.... Heck, I've seen small trees growing in gutters if
people dont clean them.
