My roofer proposed a light weight concrete tile roof with “Wedge-It” for my home to meet my requirements for an energy efficient walkable roof. It turned out that this combination didn’t work as advertised and the tile cracked and broke easily under foot traffic. However, by the time that was discovered the underlayment and battens were complete.
I am now proceeding with a metal standing seam roof. The roofer pulled up the battens and smeared some caulk-like substance on the batten staple holes. In addition, tile specific solar panel mounts were removed on a 400 square foot area which left about 100 1/4 and 5/16 inch holes. These too were caulked. Is this sufficient preparation for the metal standing seam roof installation?
The underlayment is marked “Elastoflex SA V, fiberglass reinforced SBS membrane base sheet.” I don’t know what the caulking material is, but it is light tan in color.
