This invention relates to spaced vent parts for placement between upstanding seam joints/stiffening profiles of a roofing system in the ridge area of a roof, and in particular, the invention relates to vent parts including a plurality of vent openings extending parallel to the joints/stiffening profiles and furthering including a filter member that seals around the vent parts.
In one well-known type of roof for use of the subject invention, metal roofs are widely used and as with most sloped roofs require venting through an opening in the ridge of a roof. Additionally, metal roofs are known to expand and this type of expansion can cause uneven movement, noise, and wear of high wind dome caps and associated venting closures. An additional problem is that of environmental forces such as wind, ice or snow compressing high wind dome caps to a point where water does not run off. Additionally, the expansion of the metal roof may vary from panel to panel and from side to side along the roof thereby causing additional problems with prior art top cap ventilation systems.
One prior art patent disclosing a metal roof ventilation system is U.S. Pat. No. 5,352,154 to Rotter et al. The system in Rotter et al includes segments of air-permeable venting sections located between standing seams or ridges in the metal roof. Clips are provided that include a groove for receiving air permeable venting sections, and fasteners may be used to secure a roof cap to the clips. The preferred venting material is a non-woven synthetic fiber matting.
Another venting system for metal roofs is disclosed in U.S. Pat. No. 9,151,059 B2 to Pavlansky et al. Pavlansky et al. does not have individual sections between ridges/seams of the metal roof, but rather has strips having an air impermeable backing. The backing members include contours to fit over stiffening ridges on the metal roof. Between the contours, open cell foam members are adhered to the backing member to provide venting to the roof.
U.S. Pat. No. 7,788,856 B2 to Spengler et al. disclosures a closure rail for roofing. The closure rail may be secured along a ridge, hip, or eave of a roof to receive and secure panels in a roofing system.
U.S. Patent Application Publication No. 2008/0034685 A1 to Ogletree discloses a roof ventilation device. The system may include a core, a filter and a spanner. The core can be configured to conform to a roof surface irregularity. The filters are configured to hinder rain and debris from entering into the vent opening, and the spanner is configured to allow the roof ventilation system to be adjustable for roof slopes.
U.S. Patent Application Publication No. 2006/0280911 A1 to Verkamp discloses a universal roof enclosure, including a strip of visco-elastic foam, on top of which is affixed a strip of closed cell foam. When the closure is positioned between a corrugated roofing panel having a valley or trough, strips of the visco-elastic foam expand to fill adjacent voids to prevent the passage wind, rain, noise and animals. The visco-elastic foam is designed to confirm to ridges on the roof. A ventilation member is provided that consists of strips of corrugated plastic having a multiplicity of open channels that may be attached atop the closed cell foam strip.
U.S. Pat. No. 6,599,184 B2 to Morris discloses a ridge capped vent including strips of corrugated material placed over foam rubber strips, which are designed to accommodate the non-even contours presented by ribs and lips on steel sheet roof panels.
U.S. Patent Application Publication No. 2001/0052207 A1 to Davis discloses a roofing ventilation system including vent panels extending across and perpendicular to ridges on a roof. The vent panel includes vent openings there through. The vent panels are attached to rain closures which comprise a face and upper and lower flanges extending from opposite ends of the face. The rain closures may be formed from single pieces of metal and are located between the ridges on a roof. Only the rain closures which do not accommodate venting are sectioned between the ridges, whereas the vent panel extends across the length of the roof.
U.S. Pat. No. 6,105,314 to Stocksieker discloses a panel system for use on walls and roofs. The system includes upper panels mounted on a filler board with a notch formed at the base of the filler board on both vertical edges and a lower panel locked into the notch. Vertical edges of the upper panels are folded over edges of the lower panels to form a sealed joint and retain both panels in place.
U.S. Pat. No. 3,828,494 to Uhrhane et al. discloses a roof jack. The jack has a channel which receives water flowing down a roof and diverts the same around stacks or vents so that the water continually flows and no puddles are formed.
In one embodiment of the invention, a roof ventilation system is provided that is configured to be mounted on a profiled paneled roof for venting air from a vent opening in the roof. The roof ventilation system can include a vent part having a plurality of vent passages, a plurality of plies configured to be mounted substantially horizontal to the profiled roof panels and a plurality of cross members extending between each ply, wherein the plies and cross members define the vent passages; and a filter member attached to outer surfaces of the vent part. The filter member can be made from a resilient material, and the filter member may include extensions extending beyond a length of the vent part.
The vent part can be configured to be mounted between adjacent upstanding projections on the profiled paneled roof, and the vent passages may run substantially parallel to the projections. The extensions can be located between the vent parts and respective projections.
The filter member may be provided in a sheet form and be in contact with outer surfaces of lower and upper plies of the vent part. In one embodiment, the filter member covers outer openings of the vent passages, and before installation, and the extensions have a generally U-shaped configuration. The extensions are folded about outer ends of the vent parts, and the resilient material of the filter members expands to fill any gaps between the outer ends of the vent parts and the projections.
The roof ventilation system may also include adhesive pads attached to an outer surface of the plies for temporarily attaching said vent part to the profiled paneled roof.
The roof ventilation system may further include at least one additional layer of material attached to an outer ply of the vent part. The additional layer of material includes a plurality of plies, cross members extending between each ply, and through passages defined by the plies and cross members of the additional layer. The through passages extend substantially perpendicular to the vent passages.
In another embodiment of the invention, a method for venting a roof covered with profiled panels is provided that includes the steps of providing a vent opening in a roof covered with a plurality of profiled panels; providing a vent part having a plurality of vent passages, a plurality of plies, and a plurality of cross members extending between each ply, the plies and cross members defining the vent passages; attaching a filter member to outer surfaces of the vent part, the filter member being made of a resilient material and including extensions extending beyond the length of the vent part; providing a plurality of upstanding projections on the metal panels on the roof, the projections extending substantially perpendicular to the vent opening; folding the extensions about outer ends of the vent part; and mounting the vent part between adjacent projections so that the vent passages run substantially parallel to the projections.
The method for venting a roof covered with profiled panels may also include the step of attaching the filter member to outer surfaces of upper and lower plies of the vent part.
The method for venting a roof covered with profiled panels may further include the steps of providing adhesive pads on the outer surface of the lower ply, wherein the adhesive pad is not covered by the filter member, and temporarily attaching the vent part to one of the metal panels on the roof using the adhesive pads. The extensions may have a substantially U-shaped configuration before being installed on the roof, and when installed on the roof between projections, and the extensions on the filter members expand to fill any gaps therebetween. The filter member may cover outer openings of the vent passages.
The method for venting a roof covered with metal may include the steps of providing a ridge cap, and covering the vent opening and the vent part with the ridge cap.
In one embodiment, the method for venting a roof covered with profiled panels may include the step of providing at least one additional layer on the vent part wherein the additional layer has a configuration different than the vent passages, plies and cross members of the vent part. The method for venting a roof covered with profiled panels may also include the steps of providing a plurality of through passages, plies, and cross members, to define the additional layer, the through passages running substantially transverse to the vent passages.
The method for venting a roof covered with profiled panels may additionally include the step of attaching the additional layer to an outer surface of one of the plies on the vent part.

Roof ventilation system 10 includes a plurality of vent parts 30, filter members 32, and a ridge cap 34. Referring now to
Now referring to
Vent parts 30 may include adhesive strips 46 or other fastening strips such as velcro strips, on the bottom ply (see
Regarding filter member 32, in the embodiment shown, the filter extends along the length of the vent parts and there beyond as discussed below in further detail. Filter members can be provided in a sheet form which may be a non-woven fabric, and in particular, may be in polyester fiber-bonded material having polyvinyl chloride binder. In one embodiment, the filter members include 60% fiber and 40% binder. The filter material is preferably flame retardant but may be heat sealable. In the embodiment shown, the filter members are attached to the top ply 42 of vent parts 30 wrapped over and cover the front or outer openings of vent passages 40 (i.e., the openings of vent passages 40 to be placed closest to the ridge 14 or vent opening 20 in roof 12) and then at least partially overlapping and attached to bottom ply 42 of vent parts 30 which will be in contact with profiled roof panel 22 when assembled. It should be appreciated that filter member 32 may be attached to vent part 30 using an adhesive however other suitable bonding processes may be utilized such as infrared heat or by impulse sealing. It should be further appreciated that filter member may be completely adhered to the vent part 30 or may be only attached along the top and bottom vent plies. If impulse sealing is used, pressure may be applied to the filter member with a flat heated wire strip running the length of the vent. It is further possible that the strip may be only attached to the top and/or bottom ply and not both. For instance, when vent part 30 is mounted in place on sheet panel 22 and screws or other fasteners are used to attach it, such assembly would maintain this filter member in place. It should further be appreciated the filter member may be water repellent and water non-absorbing to help keep snow and rain from entering into vent opening 20, or alternately, the filter member may be water absorbing. A water absorbing material would allow dirt, dust and other debris caught in the filter to be flushed out when hit by precipitation but may still keep out sufficient volume of moisture to prevent it from entering into vent opening 20.
