Abstract: A tile roof ridge vent and the method of its use and construction are disclosed. The ridge vent may include an elongated vent body including a flange extending from a side of the body and configured to engage a roof deck, and one or more vent openings defined in the vent body. The ridge vent may further include a first barrier to intrusion of a first element to the vent openings and a second barrier to intrusion of a second element to the vent openings. The ridge vent may further include a perforated closure and an end cap pitch gauge. Additional systems and methods are also provided.

Abstract: A ventilation system for a tile roof includes an elongated vent body defining a channel and securing features integrated with and extending from each side of the elongated vent body, where the securing features are configured to engage with a roof deck of the tile roof. The ventilation system further includes a support member received in the channel of the elongated vent body.

Abstract: A packaging comprising: (a) an outer card having one or more cavities; and (b) one or more blister cards housed within the one or more cavities, wherein the one or more blister cards are removable from the one or more cavities so that the one or more blister cards are disposable separate from the outer card.

Abstract: A roofing system in a building structure having a ridge vent includes strips of composite material having a base material adapted to form a hermetic seal with the top surface of a roofing section and recesses in a top surface in which an air permeable material can be positioned. A strip is applied to roof sections adjacent to each side of a ridge vent so that a ridge cap can overlay the strips in spaced relation from the underlying roof sections and be sealingly secured to the roof sections. The strip material establishes a barrier between the ridge cap and the roof sections through which air can pass, but through which the passage of rain and insects is inhibited.
