  • a typical tile roof is depicted in Figure 4 generally at 50.
  • the tile roof 50 has a center beam 52 supported by rafters or chords 54 (if trusses are used).
  • Underlayment or decking 56 is attached to the rafters 54.
  • Cross members 58 are then attached to upper surfaces of the underlayment 56.
  • S-tiles 60 are then disposed so as to be supported by the cross members 58.
  • At the ridge or apex of the roof 50 a cap tile 62 is placed over the final row of S-tiles.
  • proper ventilation of tile roofs is a requirement for longevity and function. However, when the roof 50 is not properly ventilated, a number of adverse effects may result.
  • a slit 64 is formed between the underlayment 56 and the center beam 52.
  • one embodiment of the instant vent assembly is indicated generally at 100, and includes a vent member 104 and a baffle 106.
  • the vent member 104 includes at least one panel, e.g., panels 110, 112, 114, and 116.
  • the panels 110-116 may be formed from a corrugated material, which is made from a synthetic resin. Suitable methods for forming the instant vent member are disclosed in U.S. Patents Nos. 5,947,817, 6,450,882, and 6,623,354, each hereby incorporated by reference.
  • One method is scoring alternate generally planar plies (described below) of a sheet of corrugated material and folding along the scores to define the individual connected panels, hi the embodiment depicted, airways 118 are defined by a cooperation of generally planar plies 120 and a convoluted ply 122 operably disposed between the planar plies 120.
  • a membrane porous to air flow may also be included in the instant vent assembly. If present, the membrane may be disposed in a substantially similar manner as disclosed in the above-referenced U.S. Patent No. 6,623,354.
  • the baffle 106 includes singular, or otherwise integral, respective first, second, and third sections 128, 130, and
  • first and second bends 134 and 136 Construction of the instant vent assembly is completed by adhering the vent 104 to the first section 128 of the baffle 106 by adhesives, screws, rivets, or other fasteners known to the art.
  • vent 104 is laminated board made from a synthetic resin such as high-density polyethylene (e.g., 140-160 pounds per 1000 square foot), hi one embodiment, the vent member 104 is adhered to the baffle 106 by an adhesive, such as a copolyamid.
  • the baffle 106 may be formed from materials such as metals or synthetic resins having the requisite stiffness and resilience.
  • the instant vent is affixed to the headboard 52 by fasteners such as nails or screws; however, adhesives known to the art may be used as well.
  • the second and third sections 130 and 132 extend generally outboard from the headboard 52.
  • the cap tile 62 may then be installed directly over the last tier of S-tiles.
  • a covering member 140 may be disposed over the S-tiles as depicted in Figure 4.
  • One suitable embodiment of the covering member is disclosed in U.S. Patent No. 6,598,353, hereby incorporated by reference.
  • the cover member 140 has alternating upper and lower undulations 142 and 144 extending from a generally linear upper surface 146.
  • the upper surface 146 of the covering member 140 is inserted beneath the second and third sections 130 and 132 of the baffle 106 such that the upper undulations are disposed over, and cover, the tiles.
  • the cap tile 62 is then disposed over the covering member 140.
  • the covering member 140 and the baffle 106 cooperate to seal the portion of the slit 64 not occupied by the vent 104, thereby preventing ingress of moisture, particulates, and insects.
  • an alternative way of sealing the portion of the slit 64 not occupied by the instant vent is to pour a sealant such as mortar, grout, or caulking therein so that the sealant solidifies in the unoccupied portion of the slit 64.
  • the layer of stiffened mortar effectively prevents ingress of water, particulates, and insects into the inner portions of the instant roof.
  • the vent assembly 100 When installed as indicated, the vent assembly 100 allows air circulation by providing air egress from within the instant roof to the exterior thereof, the air flowing through the airways 118 as indicated by arrows 148.
  • the vent assembly 150 includes a vent 152, an optional membrane 154, and an adhesive member 156.
  • the vent 152 has a top panel 160 and at least one, e.g., two, vent members 162, each vent member 162 including a plurality of vent panels 164.
  • a route 168 may be formed in the top panel 160 proximate an interior surface 170 in the manner disclosed in U.S. Patent No. 6,623,354, wherein the route 168, optionally generally coaxial to the top panel 160, is formed.
  • the route 168 may be formed by removing a generally linear portion of the bottom ply 204 and at least a portion of the underlying intermediate ply 206, so that the route 168 extends through the bottom ply and into the intermediate ply, thereby defining inner openings 208 of additional airflow passages 118.
  • the membrane 154 may be constructed from a filtering fabric such as that disclosed in U.S. Patent No. 6,623,354, e.g., polypropylene.
  • materials suitable for other embodiments include any reasonably thin, air permeable, water resistant substances, optionally formed into sheets. Woven and non-woven fabrics may be used as well as air permeable water resistant membranes which are not fabric, hi one embodiment, the instant filtering fabric allows at least about 75 percent of the air to flow through the filter that would do so if the filter were not present.
  • the instant filtering material or membrane thus may include non-woven, spunbonded materials of randomly arranged synthetic polymer fibers. A sheet of the instant air permeable, water resistant, woven or nonwoven fabric or other membrane may be applied to the bottom side of the vent.
  • the filtering fabric is bonded to the corrugated material proximate the peak of the vent and on the bottom surfaces of the stacked, corrugated vent material.
  • the instant filtering fabric is bonded proximate the peak of the vent and on interior sides or exterior sides of the stacked, corrugated vent material so as to filter airflow through the vent members themselves.
  • the filtering fabric forms a tent like structure such that any accumulated rainwater drains out through the bottommost layer of the stacked side vent portions of the ridge vent.
  • the instant vent having vent panels may be made from a three-ply weatherproof material 200 having generally planar first and second plies 202, 204 and a convoluted (fluted) intermediate ply 206, the planar and intermediate plies joined together to form air passages 118 therebetween.
  • a three-ply weatherproof material 200 having generally planar first and second plies 202, 204 and a convoluted (fluted) intermediate ply 206, the planar and intermediate plies joined together to form air passages 118 therebetween.
  • an alternate three-ply material 210 has a plurality of cross walls or cross plies 212 extending generally transversely between the generally planar plies 202, 204 to form air passages 118 bounded by the cross plies 212 and the planar plies 202, 204.
  • Figure 13 depicts how a two-ply material 220 may be used which has one generally planar ply 202 and one convoluted ply 206, the air passages 118 being defined between the convolutions of the convoluted ply and the planar ply. Whenever two or more layer of the two-ply material are used, still more air passages 118' are formed between contacting convoluted plies.
  • the top panel 160 and vent panels 164 are formed in a substantially similar manner as discussed above with respect to the panels 110-116 and airways 118.
  • the top panel 160 and vent panels 164 may be formed by techniques termed slit scoring, nick scoring, and severing.
  • slit scoring scoring is effected in two opposing orientations ( Figure 14).
  • a slit or score is extended through an upper ply and the underlying intermediate ply.
  • a slit or score is extended through a lower planar ply and the overlying intermediate ply.
  • the slit orientations are laterally alternated to provide defined top and vent panels, which can be assembled by Z- folding into an assembled, stacked vent.
  • a slit of the first orientation 250 is effected on each lateral edge of the top panel 160 and a slit of the second orientation 252 is effected laterally of the slits of the first orientation to thereby define the first pair of vent panels 164. Slits of alternating orientations are continued until all desired vent panels are formed. The first pair of vent panels 164 folds under the top panel 160, and folds over the second pair of vent panels 164'.
  • Figure 15 depicts nick scoring including lines 260 of perforations 262 to define the top and vent panels, the perforations extending through both planar plies and through the intermediate ply as well.
  • the perforated lines 260 are a series of these perforations 262. Interspersed between the perforations are intact areas 264.
  • the perforated lines thus define the top and vent panels and expose exterior openings for air passages 118.
  • the instant vent is formed by severing the top panel 160 and vent panels 164, assembling them to a contacting, stacked conformation.
  • connectors such as staples 165 are extended through the top panel 160 and sets of vent panels 164.
  • the adhesive member 156 is adhered to a lower surface 174 of the lowermost vent panel 164 of each vent member 162. Alternatively, the adhesive member 156 may be adhered to the lower surface 174 of the lowermost vent panel 164 just prior to installation.
  • the adhesive member 156 may include an adhesive tape 178 with adhesive present on a single side thereof.
  • the adhesive in turn, may be covered by strips 180, e.g., two, of a removable liner, each strip 180 longitudinally covering about one-half of the adhesive.
  • one of the liner strips 180 is removed and the adhesive member is attached, optionally so that an edge 176 of the adhesive liner generally aligns with the edges of the top panel 160 and vent members 162.
  • the other liner strip is removed and the adhesive member is attached to the upper surface 146 of the covering member 140.
  • the vent assembly 150 is then installed so that the vent members 162 generally straddle the center beam 152 and so that the covering member overlays the S-tiles 60 as described above.
  • the cap tile 62 is placed so as to rest on the instant vent assembly. Air exchange between the interior of the roof 52 and the exterior thereof is enabled via the airways formed in the vent panels 164 and top panel 160.
  • the presence of the membrane 154 prevents ingress of moisture, particulates, and insects, yet allows substantially uninhibited air exchange.
