Zusammenfassung:	A sealing system and method for a metal roof (1) having a plurality of sheet metal panels (4) attached to a roof deck (2) covered by a layer of insulation (17), such as polystyrene. The joints and seams (10) formed at junctions of adjacent panels are sealed with a non-flammable or low combustible, char forming, non-absorbent layer of material (20, 23) which is applied over the seams in a liquid or slurry form, which subsequently hardens to form a liquid proof seal to reduce the flow of molten polystyrene from melting of the adjacent layer of insulation, into the fire below.
