This membrane should be labeled high temperature to withstand the surface temperature of the roof on a hot summer day. Many single ply membrane roofs rely on the existing metal roof to function as a structural deck for support and attachment of the roof system including board insulation as well as for support of live snow and wind loads and for providing stability to the roof support members.
