We completed building our house one year ago and last winter had major issues with this valley causing snow and ice to dam and leak into the house. We were advised to line the area with copper which I am still not sure will work. The main issue we are concerned about now is the large icicle that formed on the siding causing water to leak into the house. There has been mixed opinions on gutters. Does nayone have any suggestions? We live in new England and experience alot of snowfall from December til April.
