Reynolds Posted October 22, 2008 Share Posted October 22, 2008 I am tearing off the shingles and putting on a ribbed sheet metal. My question is, should I put down Ice and Water Shield on the entire roof, the edges, or is it even necessary at all? Quote Link to comment Share on other sites More sharing options...
sparkydm Posted October 22, 2008 Share Posted October 22, 2008 Normally its only used on a shingled roof with overhangs. If you're using sheet metal, there is no way for ice to back itself under it like it does with shingles. I would say skip it. Quote Link to comment Share on other sites More sharing options...
