Ice and water shield choice | Ask The Experts Forum

Susan Trowbridge 3/5/2012	My roofer's default ice and water shield is Henry High-Temp, but he will give me Grace Ultra for an additonal cost. Because we're going to be installing the new roof over the existing asphalt shingles, the ice and water shield will only go on the stripped-off edges of the roofs. Then he'll put an underlayment over the entire roof, and metal shingles over that, on most of the house, with a PVC IB-membrane (instead of metal) on a partiularly low-sloped section where ice dams have been a big problem. I've always heard that Grace is the gold standard whena it comes to ice and water shields, but my roofer says that Henry is just as good. I don't mind paying a bit more if Grace is the way to go.

Eric Novotny An informed customer is the Best Customer! 12/15/2013	Grace has certainly benefited from a great marketing and market share but I don't think there is any issue going with the other material. If you have issues with Ice dams, I would suggest you also look into Air Sealing and Insulation.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/17157/find/
