Gutters dont make ice dams, warm attics do, gutters keep the roof water
from dumping excessive water at the buildings edge, leaking into the
basement, or even just raising humidity in the basement, I finaly fixed
a gutter last fall that never drained from a sag, this is the first year
I have not used my dehumidifier in the basement, Excessive water will
damage a foundation over time. Figure if it rains an inch maybe an
equivilant of 10 inches or whatever may be dumped at the foundation from
the roofs area .
