Abstract
A sealing system and method for a metal roof having a plurality of sheet metal panels attached to a roof deck covered by a layer of insulation, such as polystyrene. The joints and seams formed at junctions of adjacent plates are sealed with a nonflammable or low combustible, char forming, non absorbent layer of material 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.
