MetaLayment is a film-surfaced, self-adhering underlayment designed especially for use beneath metal roofing. It has been designed to resist weather elements for 6+ months to meet the needs of phased construction as well as designed to withstand the high temperatures commonly seen under metal, up to 250ºF. And, since MetaLayment meets ASTM D1970, it is also acceptable as an ice dam protection sheet under shingles, tile, and shake roofs.
