I need a way to glue ceiling tiles to a metal roof. Nailing is not an option. The metal roof is on our florida room and the heat that comes through the roof is unbearable. We dedided to put up ceiling tiles, but need a way to glue them directly to the metal roof. Does anyone know of any glue that would work with the ceiling tiles available clinging to the metal roof with variable temperatures with high above 100 degrees and possibly low as 32.
