riverat's picture

I want to put either a standing seam or 5vcrimp metal roof on my hip roof in coastal Georgia.What shouldI use as a underlayment on my  sheathing? Would it be ok to strip off the old roof and use Ice and water shield on the sheathing and then install themetal roof? Or, Ice and water shield, then rosin paper, then metal roof? I want to use the correct method and produts, Thank You.

There are various option for underlayment for metal roof For example Owens Corning - Roof -Underlayment, IKO etc for underlayment.

Don't use retrofit option for underlayment. Before installing the underlayment each seam between roof sheating panels should be sealed. IT's ok to strip off the old roof and use Ice and water shield on the sheathing and then install themetal roof
