Hi, I am a architectural sheet metal foreman and have installed many different types of metal roofs. This summer I will be installing a 26 gauge standing seam roof (Image II through Metal Sales) on my new home. On many of the commercial jobs I've done in the past, I&W (Ice & Water) shield was used for the entire application rather than 30# felts. It was often recommended by the manufacturer or required by the customer. The manufacturer of the roof I am putting on states that a 30# felt underlayment should be used. I have already applied I&W to the entire roof (which is about 5500 square feet). Now I am doubting things. Do any of you have suggestions on what type of underlayment should be used? I would appreciate any suggestions. Thanks!

If we have a good slope, 4/12 or better and we are going to roof it immediately after drying in, then we usually use 30 lb. felt. If it is going to be a while, say 3 weeks or better then we use the ice and water shield. You haven't done anything wrong. The ice and water shield is a much better underlayment than felt. You have gone the extra mile for a trouble free roof. The manufacturer is giving you the minimum that they require. [email protected]
