Description
- This application is a continuation of U.S. patent application Ser. No. 10/826,651, filed 16 Apr. 2004, which is a continuation of U.S. patent application Ser. No. 10/636,178, filed 7 Aug. 2003, which is, in turn, a continuation of application Ser. No. 10/209,851, filed 31 Jul. 2002, now U.S. Pat. No. 6,623,354 and application Ser. No. 09/651,071, filed 30 Aug. 2000, now U.S. Pat. No. 6,450,882, each hereby incorporated by reference.
- The present invention relates to roof ventilators folded from a blank of corrugated plastic sheet material having a top panel and two vent panels. More particularly, it relates to a roof vent of corrugated construction including an internal filtering material to exclude precipitation, debris and vermin from entry into the vented roof.
- It is a common practice in the construction of structures to ventilate gable roofs by providing a vent along the roof ridge. Ventilation apertures are formed in the construction process by leaving or cutting an open slot along the ridge through the sheathing material covering the roof. Heated air rises and escapes at the ridge taking with it moisture that may have accumulated within the roof. The flow of wind over the ridge of the roof assists in the extraction of moisture and heated air by creating a zone of relatively reduce pressure as it crosses the ridge. Soffit vents enable the entry of fresh exterior air into the roof to replace air that has left through the ridge vent. Soffit vents are openings in the soffit material covering the undersides of the overhanging eaves of the roof.
- Ideally, a ventilated roof provides for an unrestricted outflow of air through the ridge vent and inflow through the soffit vents. However, without protection of the ventilating openings, wind blown precipitation, debris and insects enter the roof and encourage damage to the structure through mildew, rot and infestation. A ventilated cap is therefore placed over the open slot in the ridge and attached to the roof along each side.
- Therefore, many types of vent caps have been developed in an effort to provide free flow of air while excluding rain, snow and insects. Louvers, baffles and screens have been standard features of roof vents for decades.
- Snow, in particular, is a great concern. It has a small particle size and is lightweight. Wind can carry snow upward and into roof vents readily. Snow particles may bypass louvers and deflectors that prevent the entry of most rain. As much as two feet of wind driven snow has been reported to have passed through roof vents and accumulated inside roof structures.
- A number of ridge vent caps employ filtering material to restrict the entry of precipitation and foreign matter. Filtering materials include porous foams and fibrous materials. Examples of the use of porous foams include U.S. Pat. No. 5,830,059 issued to Sells, U.S. Pat. No. 5,673,521 issued to Coulton et al. and U.S. Pat. No. 4,876,950 issued to Rudeen. Both closed cell foams and open cell foams have been utilized. Open cell foams have the benefit of allowing greater airflow but tend to absorb a substantial amount of water. Closed cell foams absorb little water but restrict airflow to a greater degree. Foam products, in general, tend to deteriorate with age and exposure to the elements.
- Fibrous materials enjoy wider use as roof vent filters. Examples include U.S. Pat. No. 5,902,432 issued to Coulton et al., U.S. Pat. No. 5,830,059 issued to Sells, U.S. Pat. Nos. 5,561,953, 5,425,672, 5,352,154, 5,167,579 all issued to Rotter. These patents and others disclose the use of mats of randomly aligned synthetic fibers to exclude vermin and the elements from roof vents. The Rotter patents disclose roof vents made entirely from mats of randomly aligned synthetic fibers. Fiber mats may suffer from compression, for example, under a snow load, and add expense and complexity to the construction of roof vents.
- Another approach to preventing the entry of precipitation and foreign matter into vents is to employ check valves structured to close at a predetermined wind speed so as to stop the inflow of air and precipitation. Check valves have moving parts and are prone to the possibility of wear and blockage and when they operate ventilation is restricted. They also complicate the manufacturing process. U.S. Pat. No. 5,803,805 to Sells discloses a check valve ridge vent.
- In recent years the use of corrugated plastic sheet materials to manufacture roof vents has presented to the marketplace a variety of inexpensive, strong, durable ridge vents which may be applied in sections or as a continuous roll. Ridge vents of this type are typically applied along the peak of a roof and covered by a row of shingles. They are thus referred to as “shingle over roof vents.” Some have sufficient structural integrity such that they can be fastened to the roof with a pneumatic nail gun without crushing the vent.
- Examples of corrugated plastic ridge vents include U.S. Pat. No. 5,651,734 issued to Morris, U.S. Pat. No. 5,934,995 to Morris, Kasner and Stoll and U.S. Pat. No. 5,947,817 to Morris, Gosz and Stoll which are incorporated herein in their entirety by reference.
- Wind deflectors are sometimes installed along with the vent in order to restrict the entry of rain and snow into the vent. The installation of wind deflectors requires an additional step in the installation process with an attendant increase in time and expense.
- The applicant is aware of a single example of a corrugated ridge vent employing a filtering material to exclude precipitation and the like. U.S. Pat. No. 5,704,834 issued to Sells discloses the use of a flexible, air permeable, moisture repelling, woven or non-woven fabric covering the outer side of the vent passages to resist the penetration of moisture into the vent passages. The fabric filter is held in place by a perforated metal flashing attached either to the roof or to the vent.
- Considerable complexity is added to the manufacturing process in order to incorporate the flashing into the vent. The presence of a rigid or semi rigid flashing may also prevent or complicate the rolling of the vent for transport and reduce ease of application. Additionally, the filtering fabric is exposed to the elements. Sun and wind may accelerate its deterioration.
- It would be desirable to produce a ridge vent of folded corrugated plastic construction that effectively excludes wind blown precipitation and other foreign matter. The process of manufacturing the ridge vent should be as simple as possible. It would be preferable for such a ridge vent to require no flashing to support the filtering material. The ridge vent would ideally be possible to produce either in a continuous roll or in discrete sections. It would be preferable that filtering material be protected from exposure to the elements to maximize its life.
- The present invention largely solves the above problems by providing a shingle over ridge vent that effectively excludes the entry of precipitation and foreign matter into the roof space. The ridge vent is sturdy, easily manufactured and readily installed. In addition, the filtering material that excludes precipitation is protected from factors that speed its deterioration.
- The ridge vent is constructed of corrugated weather resistant material having a convoluted intermediate ply. Airflow passages in the convoluted layer are linearly oriented generally perpendicular to the long axis of the ridge vent.
- The material is cut and scored so that it may be folded to have a single top panel extending its entire length. At either side of and below the top panel a plurality of folds create a plurality of stacked layers of the corrugated material with a plurality of airflow passages therethrough. A routed groove may extend the length of the bottom side of the top panel of the ridge vent to facilitate bending the ridge vent to conform to different roof pitches and to provide an additional exit path for air flowing out of the ridge vent.
- A sheet of air permeable, water resistant, woven or non-woven fabric or other membrane is applied to the bottom side of the vent. The filtering fabric is bonded to the corrugated material in the vicinity of the peak of the vent and on the bottom sides of the stacked, corrugated vent material. When the ridge vent is applied to the roof ridge 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 enclosure of the filtering fabric inside the ridge vent protects the fabric from exposure to sunlight and other factors that encourage deterioration.
- The ridge vent may be produced in lengthy continuous rolls or discrete sections for installation. Discrete sections of ridge vent may be stacked flat or folded then stacked for shipping and handling. Multiple sections may be butted together end to end to cover a lengthy ridge application.
- The vent material is unrolled or unfolded and disposed along the roof ridge so as to straddle the precut slot in the roof sheathing. The ridge vent may then be secured to the roof ridge with fasteners such as nails. It may be caulked as necessary. An individual skilled in the art will appreciate that if a roof is substantially irregular such as a corrugated metal roof or a tiled roof that a resilient conforming material may be placed beneath the ridge vent to provide a tight seal between the ridge vent and the roof. An end plug of resilient foam or other appropriate material may be inserted and secured in the end of the roof vent to close off the opening there. The ridge vent then may be covered with shingles nailed directly through the ridge vent into the roof sheathing.

FIG. 1 depicts the precipitation resistant ridgecap roof vent 10 being installed on aroof 12. The roof depicted is a rafter roof, though theridge vent 10 may be installed on many other types of roofs to provide ventilation. Theroof 12 depicted includesrafters 14 secured to aridge board 16.Rafters 14support sheathing 18.Sheathing 18 may be of plywood, oriented strand board, planks or other suitable material secured torafters 14. Generally sheathing 18 is overlaid with tarred feltpaper 20 which is in turn overlaid withshingles 22, though other roofing materials may be employed. Acutout slot 24 is provided along theridge 26.Slot 24 may terminate some distance from theend 28 of theridge 26. - The
ridge vent 10, as depicted inFIGS. 1, 5 , 6, and 7, broadly includes atop panel 30, a plurality ofvent panels 32 andfiltering fabric 34.Top panel 30 presents along axis 36 aligned generally parallel with theridge 26 of theroof 12 whenridge vent 10 is installed.Top panel 30 and ventpanels 32 are constructed of a weatherproof three-ply material 38 including a generally planartop ply 40, a generally planar bottom ply 42 and anintermediate ply 44. Theintermediate ply 44 defines a multiplicity ofairflow passages 46 extending generally transversely tolong axis 36 and entirely acrosstop panel 30 and ventpanels 32.Plug 47 may be inserted in the end of theridge vent 10. -
FIGS. 2, 3 and 4 depict several possible configurations of the three-ply material 38.FIG. 2 depicts a three-ply material 38 whose intermediate ply is comprised of a series ofcross walls 39 connecting the top ply 40 to bottom ply 42 and defining a plurality ofairflow passages 46 therebetween.FIGS. 3 and 4 depict anintermediate ply 44 of one or several convoluted orfluted layers 48 defining a plurality ofairflow passages 46.FIGS. 3 and 4 also show how multiple layers of three-ply material 38 may be stacked to provide many generallyparallel airflow passages 46 therethrough. -
Top panel 30 also presents anexterior surface 50 and aninterior surface 52.Interior surface 52 may include a routedgroove 54 usually extending generally parallel tolong axis 36. Routedgroove 54 extends throughbottom ply 42 and intointermediate ply 44 defininginner openings 56 ofairflow passages 46. The outer edges 58 oftop panel 30 define theouter openings 60 ofairflow passages 46. -
Vent panels 32 are disposed under theouter edges 58 oftop panel 30 in a stacked fashion. They contain a multiplicity ofairflow passages 46 oriented generally transverse tolong axis 36.Vent panels 32 may be formed by scoring and folding a sheet of three-ply material 38 as depicted inFIG. 5 .Vent panels 32 may then be secured totop panel 30 by the use of adhesives orfasteners 62 such as staples. - Alternately, vent
panels 32 may by cut separately and stacked beneath theouter edges 58 oftop panel 30 and secured together and totop panel 30 withfasteners 62 or adhesive. Thusairflow passages 46 are formed extending fromexterior edges 64 tointerior edges 66 ofvent panels 32. - Filtering
fabric 34 is secured along theinterior surface 52 oftop panel 30, preferably in the region of the routedgroove 54, and on thebottom side 68 of thelowermost vent panel 32 extending the length of theridge vent 10. Adhesives, fasteners, heat fusing or any other suitable technique may securefiltering fabric 34 to theridge vent 10. - Filtering
fabric 34 may be of any thin, air permeable, water resistant, sheet material. Woven or non-woven fabrics may be employed as well as air permeable water resistant membranes that are not of fabric. Preferably, filteringfabric 34 allows passage of about 75 percent of the air that would flow were it not present. Thefiltering fabric 34 may be a non-woven spunbonded material of randomly arranged synthetic polymer fibers. - Referring to
FIGS. 6 a and 7 a, in an alternate embodiment ofridge vent 10filtering fabric 34 may be applied directly overinner openings 56 ofairflow passages 46. Filteringfabric 34 may cover onlyinterior edges 64 ofvent panels 32. - Alternately, as depicted in
FIG. 6 b filtering fabric 34 may extend frombottom side 68 ofvent panels 32, up overinner openings 56, acrossinterior surface 52 oftop panel 30, down overinner openings 56 on the opposite side and ontobottom side 68 on the opposite side. Thefiltering fabric 34 may be secured tointerior edges 64,bottom side 68 ofvent panels 32 andinterior surface 52 oftop panel 30 as required. -
FIG. 8 depicts an alternate embodiment of theridge vent 10 adapted for use where it is desire to ventilate ashed style roof 70 in contact with anexterior wall 72. Shed roof vent 74 generally includes a generally planartop panel 76,vent panels 32 andfiltering fabric 34. Planartop panel 76 includesflange panel 78 extending along its length.Vent panels 32 are disposed beneathtop panel 76 and are stacked and secured in a similar fashion toridge vent 10. Filteringfabric 34 is attached along thebottom side 68 of thelowermost vent panel 32 and to planartop panel 76 on or nearflange panel 78. Filteringfabric 34 may also be attached to cover theinterior edges 66 ofvent panels 32 alone. Fasteners, adhesives, heat fusing or other suitable techniques may securefiltering fabric 34 to planartop panel 76 and ventpanel 32. Flashing 80 may overlie theshed roof vent 74. - Referring to
FIG. 1 , in operation,ridge vent 10 is applied to theridge 26 of aroof 12 over a previously madecutout 24 extending the length of theridge 26 except for a small portion left uncut at each end of theroof 12. Thecutout 24 may be larger than a cutout that would be used with a non-filtering ridge vent in order to compensate for the restriction of airflow caused by thefiltering fabric 34. Theridge vent 10 is unrolled or unfolded if it is received packaged in either of these forms. Theroof vent 10 is disposed so that the routedgroove 54 is generally centered over thecutout 24 and thevent panels 32 are generally parallel to theshingles 22 or other roof surface. It will be appreciated by those skilled in the art that a resilient or conforming piece of material may be placed between theridge vent 10 and theroof 12 to fill in any gaps that may be present due to any substantial irregularities in the roof structure. This may be helpful in the case of a corrugated metal or tiled roof. - Once in place, the
ridge vent 12 may be secured to theroof 12 by fasteners such as nails or by adhesives. Nails may be applied directly throughtop panel 30 where it overlies ventpanels 32 and intoroof sheathing 18. A ridgeline (not shown) ofshingles 22 may be applied directly overridge vent 10. - As can be seen in
FIGS. 1 , and 7, when the ridge vent is installed thefiltering fabric 34 forms a tent like structure. Wind blown precipitation such as rain or snow may be carried into the interior of theridge vent 10 throughairflow passages 46 but it is stopped from traveling further by the waterresistant filtering fabric 34 while air may still pass. Liquid rain or melted snow that accumulates on top of thefiltering fabric 34 drains from theridge vent 10 through the lowermost layer ofairflow passages 46 invent panels 32 onto theroof 12 where it may run offshingles 22. - In the embodiment depicted in
FIGS. 6 a and 6 b, wind blown precipitation may be carried intoairflow passages 46 but is prevented from proceeding further by filteringfabric 34 and may drain back out. - Referring to
FIG. 8 , shedroof vent 74 is applied at the top of ashed style roof 74 where it abuts anexterior wall 72.Flange panel 78 may be bent downwardly and secured toexterior wall 72 by fasteners or adhesive. Alternately, theflange panel 78 may be bent upwardly and secured to thewall 72. Flashing 80 may be applied on top of theshed roof vent 74.Vent panels 32 may be nailed or otherwise secured to sheathing 18 throughshingles 22. Any wind blown precipitation that enters theshed roof vent 74 is prevented from entering the space beneath the roof by filteringfabric 34. Rain or melted snow that accumulates on top of filteringfabric 34 drains from theshed roof vent 74 through theairflow passages 46 in thebottommost vent panel 32. - The present invention may be embodied in other specific forms without departing from the essential attributes thereof; therefore, the illustrated embodiments should be considered in all respects as illustrative and not restrictive, reference being made to the appended claims rather than to the foregoing description to indicate the scope of the invention.
