Abstract
A roofing ventilation system for a metal building. The system includes a compressible seal between a corrugated sheet metal roof and a roof vent of the system. Further, the present invention utilizes an insulating block having venting capability in order to allow moisture and hot air in the roofing system to escape, thereby reducing corrosion of the metal roof and deterioration of the insulating ability of the insulation material. In one embodiment, the system includes a shield between the insulating vent block and insulation material, such that insulation adjacent a compressed area of material does not obstruct the air passages of the insulating block. In one embodiment of the present invention, the compressible seal is a sealing strip that conforms to the profile and shape of the corrugated roof. The sealing strip is formed from an open-celled foam material and has a plurality of slits to provide an environmental barrier across the length of the corrugated roof. In an embodiment of the present invention, two ventilation strips are aligned along a ridge opening in the roof in an effort to vent air and evacuate moisture from the system that has transferred through one or more insulating vent blocks.
