Abstract: A ventilation system to be used over roofing materials that have ribs or corrugations on their surface such as might be found on preformed metal roofing panels. This ventilation system consists of narrow strips of material that are to be placed end to end in such a way as to form a long continuous strip. They are then covered by a typical ridge cap or other flashing material allowing the ventilation air to pass over the roofing material but under the ridge cap or flashing material. The resulting ventilation system is impervious to normal temperature extremes and wind born materials such as rain or snow.

Abstract: A new roof ventilation system is disclosed that employs unique properties that enable it to ventilate said roof system in a simple, economical, and effective manner. This ventilation system is designed to be used in an application over roofing materials that have ribs or corrugations on their surface such as might be found on pre formed metal roofing panels. This ventilation system consists of narrow strips of material that are to be placed end to end in such a way as to form a long continuous strip. They are then covered by a typical ridge cap or other flashing material allowing the ventilation air to pass over the roofing material but under the ridge cap or flashing material. The resulting ventilation system is aesthetically pleasing, economical, functional, and impervious to normal temperature extremes and wind born materials such as rain or snow.
