I live in the N.E. where there is lots of rain and snow. The house does not have gutters and leaders. (told not to use in order to prevent ice dams) A leak has developed along 3 ft of the basement wall. It appears to be the result of water coming off the roof at that place in great quantity during a heavy rain. What is your opinion about running a gutter on that side of the house to carry away the rainwater?
