Abstract: Disclosed are sealing apparatuses used in conjunction with corrugated roofing around chimneys, vents, solar tubes, and other structures protruding through corrugated roof or siding. In one embodiment a specialized gasket comprising gasket ribs having a profile that matches a chosen corrugated sheet metal barrier is utilized. A transition barrier hole is cut into the corrugated sheet metal barrier and then the hole is used to cut a transition gasket hole in the gasket. A sealant is used between the gasket and mating parts to create a seal about the transition vessel to prevent roof leaks. In some embodiments, the gasket is in the form of gasket plugs which may be trimmed and utilized to plug and seal the corrugations surrounding a transition barrier hole in a corrugated sheet metal barrier.
