Ventilated roof system with ridge vent

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.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) A building structure 10 having a roof system incorporating the ridge vent of the present invention is shown in FIG. 1 to have sidewalls 12, gables 14 at opposite ends (only one being shown), and an inverted v-shaped roof structure 16 having a pair of roof sections 18 intersecting along an apex or ridge 20 of the roof. A conventional slot or ridge opening 22, as possibly best seen in FIG. 2, is established along the ridge of the roof system with the slot being established between layers of decking material 24 associated with each roof section 18 with the decking being supported on rafters 26 which are in turn interconnected with a longitudinal beam 28 as is common in the building trade. The decking 24 is overlaid with an outer covering 30 of roofing material which in the disclosed embodiment is composed of interconnected, elongated strips or channels 32 of metal or the like of generally u-shaped cross-section even though the invention would be applicable to flat outer coverings or outer coverings of corrugated materials, tile, or the like.

(11) As probably best appreciated by reference to FIG. 5, while the channels 32 which extend perpendicularly to the ridge 20 of the roof system can be formed in many different ways, the channels used to facilitate a description of the present invention are elongated, having complementary opposite longitudinal edges so that the edge of one panel can overlap and be releasably connected to the opposite edge of the next adjacent channel. At the interconnection 34 of adjacent channels and at one or more spaced locations 36 therebetween there are upstanding ribs or projections of generally trapezoidal transverse cross-section extending parallel to the longitudinal edges of each channel 32. Such channel formed roofing materials are common in the trade and are illustrated for exemplary purposes only. It will be appreciated by reference to FIG. 5 that when adjacent channel members 32 are interconnected along adjacent edges, with one edge overlapping the opposite edge of an adjacent channel member, the entire outer covering 30 for the roof decking is established with upstanding ribs 34 and 36 extending perpendicularly to the ridge 20 and the lower edge 38 of the associated roof section 18.

(12) The upper ends of the channel members 32 forming the roof covering 30 of one roof section 18 are spaced from the upper ends of the channel members on an adjacent roof section similarly to the spacing of the upper edges of the decking 24 for each roof section so that the opening or slot 22 is defined along the ridge permitting the egress of air from beneath the roof structure through the opening.

(13) Sealant strips 40 in accordance with the present invention are secured to the top surface of each roof section 18 adjacent to and along each side of the opening 22. The securement is in any suitable manner but preferably with an adhesive so as to establish a fluid seal or barrier between the strip and the underlying roof section.

(14) The sealant strip 40 as best appreciated by reference to FIGS. 5-9, is a composite strip of two aggregated or interconnected materials with one material 42 forming the base of the strip which is connected to the underlying roof section 18, and the other material 44 an overlying material seated on the top of the base and in a position to engage a ridge cap 46. The base material 42 could be numerous materials, but in accordance with the present invention, the base material is preferably a flexible material that is also air and liquid impermeable, with an example being a cross-link polyethylene foam of two pound density. The base material has a lower surface 48 that is adapted to engage the underlying roof section 18 with this surface being formed and contoured to mate with the cross-section of the covering 30 of the associated roof section. In the illustrated embodiment, the lower surface 48 is smooth but provided with transverse channels 50 having a trapezoidal cross-sectional configuration complementary to that of the ridges 34 and 36 in the interconnected channel members 32 which form the covering 30. In this manner, when the strip 40 is laid transversely to the length of the channel members and parallel to the slot 22 in the ridge of the roof structure, the strip is in continuous engagement with the underlying channel members of the covering 30. The base material 42 has a smooth bottom surface such that the strip can be sealed to the underlying channel members to prevent the passage of fluid, insects and the like across the interconnection of the strip with the channels.

(15) In the preferred embodiment of the invention, the sealing is established with a pair of longitudinally extending strips 52 of adhesive, as seen in FIG. 9, which are spaced from each other and covered with a tear-away strip 54 of paper which facilitates shipping of the material and easy installation.

(16) The upper surface 56 of the base material as best seen in FIGS. 5-7, is provided with longitudinally spaced notches or recesses 58 of rectangular transverse cross-section which are spaced from each other by bridge sections 60 of the base material. The bridge sections of the base material have flat, continuous upper surfaces 62 for engagement with the ridge cap 46. The other composite material 44 used in the sealant strip has a lower concentration of matter so as to be air permeable and is positioned in the recesses 58 in the top surface of the base material so as to permit the free flow of air therethrough, but inhibit the passage of rain, insects, or the like. The air permeable material could be any suitable material, but a reticulated material has been found desirable that may be described as a strong, durable, modified polyester, non-woven, non-wicking, fiber-based matting of the type described in the aforementioned U.S. Pat. No. 5,167,579, the disclosure of which is hereby incorporated by reference.

(17) The air permeable material 44 is preferably, positively secured in the recesses 58 of the base material with adhesive or the like and is of a thickness such that the top surface of the air permeable material is coplanar with the top surface 62 of the bridge sections 60 in the base material. Accordingly, the cross-section of the air permeable material corresponds with the cross-section of the recesses in the base material.

(18) The ridge cap 46 which is of inverted v-shaped cross-section corresponding to the cross-sectional configuration of the interconnected roof sections is rigid and adapted to overlie the strips 40 of material which have been placed on and secured to the underlying roof sections 18 and due to the continuous height of the strip material, the ridge cap is positioned in continuous engagement with the strip material. The ridge cap can be secured in position with fasteners 64 (FIG. 6), passed through the ridge cap, the bridge section of the base material, and into the upstanding projections or ridges 34 and 36 of the channel members forming the covering 30 or outer surface of the roof sections.

(19) It will therefore be appreciated with the ridge cap 46 secured to the roof sections and the strip material sealing the space therebetween that an air permeable connection is established between the ridge cap and the underlying roof sections through which air can easily pass but through which rain, insects or other such undesirable materials are inhibited from passing. Further, the strip is sealed to the underlying roof section 18 to prohibit the ingress of rain, insects, and the like between the two materials.

(20) It should also be appreciated from the above description that the system of the present invention can be easily installed by one individual who can first apply the elongated strips 40 of material to the underlying roof sections 18, with the strips of material remaining in place due to the adhesive 52 or other suitable connective material on the strips. Once the strips have been properly positioned, the ridge cap 46 is easily laid over the strips on opposite sides of the slot 22 in the ridge 20 of the roof structure and secured to the underlying roof sections 18 through the strip material with the fasteners 64.

(21) Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example, and changes in detail or structure may be made without departing from the spirit of the invention as defined in the appended claims.
