- an exemplary building 100 may have a pitched roof 105 and walls 110 .
- building 100 may be a residential, commercial, industrial, or other type of building.
- pitched roof 105 may include sloped, generally planar surfaces 120 and 125 defined by a top face of a roof covering (e.g., shingles, tile pieces, or metal) that is normally exposed to natural elements (e.g., wind, rain, and sun).
- a roof covering e.g., shingles, tile pieces, or metal
- the sloped, generally planar surfaces 120 and 125 intersect with one another at a roof ridge 130 of pitched roof 105 .
- This intersecting of the surfaces 120 and 125 may be direct or indirect.
- surfaces 120 and 125 may indirectly intersect with one another via a roof ridge cap 135 of roof ridge 130 .
- Roof ridge cap 135 may overlap outermost layers 140 and 145 of surfaces 120 and 125 , respectively, and may create a water tight seal along roof ridge 130 .
- Roof ridge cap 135 optionally may include a vent to provide venting for a building space, such as an attic, below roof 105 . In some instances, roof ridge cap 135 may extend above the respective planes defined by generally planar surfaces 120 and 125 .
- each of surfaces 120 and 125 may extend outwardly from roof ridge 130 beyond an exterior wall 110 of building 100 , and possibly also extend outwardly beyond a structural perimeter 150 of pitched roof 105 .
- Structural perimeter 150 comprises the outermost surfaces of the portions of pitched roof 105 that are positioned below surfaces 120 and 125 .
- these portions may include bargeboards 155 , trim members 157 , rafters 160 , or other portions of pitched roof 105 that are positioned below surfaces 120 and 125 .

- vortex suppressing system 165 may include a roof ridge assembly 170 to mitigate wind-generated vortices and wind loads near roof ridge 130 .
- vortex suppressing system 165 may include one or more perimeter assemblies 175 to mitigate wind-generated vortices and wind loads near structural perimeter 150 .
- FIG. 1 illustrates vortex suppressing system 165 as including two different types of perimeter assemblies 175 (fascia member 175 a and windscreen 175 b , described in more detail below), it should be understood that vortex suppressing system 165 may include only a single type of perimeter assembly 175 .
- vortex suppressing system 165 may include no perimeter assemblies 175 . It is contemplated, however, that combining one or more roof ridge assemblies 170 with one or more perimeter assemblies 175 may maximize the mitigation of wind-generated vortices and wind loads near roof 105 by mitigating wind-generated vortices and wind loads near both roof ridge 130 and structural perimeter 150 , and thereby better protect roof 105 from potential wind damage.
- Roof ridge assembly 170 may extend in generally the same direction as a length of roof ridge 130 . When viewed along this direction, as shown in FIGS. 1-3 , roof ridge assembly 170 may include a first end portion 180 , a second end portion 185 , and a bridging portion 190 joining end portions 180 and 185 .
- end portions 180 and 185 may contact surfaces 120 and 125 , respectively.
- an outermost edge 191 of a lower surface of end portion 180 may contact surface 120 at a distance D 1 from the intersection of surfaces 120 and 125 . If such intersection is indirect (e.g., via roof ridge cap 135 ), a location L of the intersection of surfaces 120 and 125 is defined to be the location where surfaces 120 and 125 would meet if they were to be extended toward one another.
- an outermost edge 193 of a lower surface of end portion 185 may contact surface 125 at a distance D 2 from the intersection of surfaces 120 and 125 .
- distances D 1 and D 2 may each be from about 5 cm to about 50 cm. It should be noted that these distances are exemplary only, and that the distances may vary based on, for example, an angle ⁇ between surfaces 120 and 125 .
- End portions 180 and 185 may be attached to surfaces 120 and 125 , respectively, using any form of fastening arrangement adjacent to roof ridge 130 .
- exemplary fastening arrangements may include adhesive, a nail, a screw, tape, a cleat, a wire, a clip, and/or other fastener.
- end portions 180 and 185 may be attached to surfaces 120 and 125 via one or more mounting portions 195
- mounting portion(s) 195 may be attached to surfaces 120 and 125 by fasteners 200
- mounting portion(s) 195 may include cleats 205 that are configured to engage end portions 180 and 185 to attach end portions 180 and 185 to surfaces 120 and 125 , respectively.
- the assembly 170 may also include at least one spring member 210 extending between roof 105 and bridging portion 190 . Spring member(s) 210 may be configured to bias bridging portion 190 away from roof 105 so as to maintain engagement of mounting portion(s) 195 and at least one of end portions 180 and 185 .
- spring member(s) 210 may extend generally upward from roof 105 , and may be deflected by bridging portion 190 upon installation of bridging portion 190 (attachment of end portions 180 and 185 to surfaces 120 and 125 ). Thus, after installation, potential energy stored in spring member(s) 210 may tend to push upward on bridging portion 190 , thereby biasing bridging portion 190 away from roof 105 and maintaining engagement of the cleats 205 to the end portions 180 and 185 .
- mounting portion(s) 195 may be located entirely within an enclosure defined by bridging portion 190 , end portions 180 and 185 , and surfaces 120 and 125 .
- substantially watertight seals may be defined between end portion 180 and surface 120 , and between end portion 185 and surface 125 . Along with the enclosure, these seals may help to maintain roof 105 substantially waterproof by preventing water from reaching the areas where fasteners 200 penetrate surfaces 120 and 125 .
- mounting portion(s) 195 may be located outside of the enclosure defined by bridging portion 190 , end portions 180 and 185 , and surfaces 120 and 125 .
- such installations may be used when the enclosure is not watertight (e.g., in embodiments of bridging portion 190 that are perforated, for example, to enhance the vortex suppressing effect of assembly 170 by inducing small-scale turbulence), or when mounting portion(s) 195 is/are attached to surfaces 120 and 125 by fasteners that do not penetrate surfaces 120 and 125 (e.g., adhesives and tapes).
- bridging portion 190 may extend over roof ridge 130 , and may have a bottom surface 215 and a generally curved outer surface 220 . Since roof ridge 130 may include roof ridge cap 135 , as discussed above, it should be understood that bridging portion 190 may also extend over roof ridge cap 135 . In some examples, it is contemplated that bottom surface 215 may be spaced vertically above an uppermost part of a top surface 225 of roof ridge 130 by a distance not larger than 25 cm. It should be noted, however, that this distance is exemplary only, and that the distance between bottom surface 215 and top surface 225 may vary based on, for example, angle ⁇ between surfaces 120 and 125 .
- outer surface 220 may have a relatively gradual changing slope.
- the configuration of the outer surface 220 alters wind flow near roof ridge 130 , and thereby mitigates wind-generated vortices and wind loads near roof ridge 130 .
- Outer surface 220 may be substantially symmetrical about a plane that is generally parallel to roof ridge 130 .
- outer surface 220 is substantially symmetrical about a plane P that bisects angle ⁇ defined by surfaces 120 and 125 .
- plane P is illustrated as being generally vertical in the embodiment of FIG.
- outer surface 220 may allow for reduction of wind-generated vortices without being significantly impacted by the particular wind direction. However, it is contemplated that outer surface 220 may alternatively be asymmetrical, and tailored for the specific configuration of roof 105 near ridge 130 and/or the prevailing wind direction.
- outer surface 220 may define a radius of curvature not less than 3.5 cm. Like the above-discussed distances, however, it should be noted that this radius of curvature is exemplary only, and that the radius of curvature may vary along outer surface 220 between end portions 180 and 185 . Moreover, the radius of curvature may vary based on, for example, angle ⁇ between surfaces 120 and 125 . Further, it is contemplated that some embodiments of bridging portion 190 may have outer surfaces 220 including substantially flat portions 230 (referring to FIG. 4 ), which may simplify the construction of assembly 170 and/or be visually appealing.
- substantially flat portions 230 may be configured so as to avoid altering the functionality of assembly 170 .
- substantially flat portions 230 may be sized and positioned such that 180° ⁇ , where ⁇ is an angle between two adjacent portions 230 , never exceeds 55°.
- vortex suppressing system 165 may also include a fascia member 175 a .

Such positioning may allow rainwater to flow from the surface 120 into the gap and then into a channel 412 defined by the fascia member 175 a below the gap.
- the topmost portion 405 may extend vertically no higher than the plane defined by the roof surface 120 . It is contemplated that the shape of outer face 400 may alter wind flow near structural perimeter 150 , and thereby mitigate wind-generated vortices and wind loads near structural perimeter 150 .
- fascia member 175 a may alternatively or additionally be positioned adjacent to surface 125 (referring to FIG. 1 ).
- fascia member 175 a could extend at least partially along more than one side of perimeter 150 , and be positioned adjacent to multiple sloped, generally planar surfaces of pitched roof 105 .

Although all serrations 465 of free end 455 may be the same size and shape, it is contemplated that some embodiments may include serrations 465 of varying size and/or shape. Moreover, it is contemplated that a layout of serrations 465 may also vary. For example, serrations 465 having different shapes could be laid out in a particular order or could be randomly distributed along free end 455 . It is contemplated that serrations 465 may disorganize air flow over free end 455 , thereby mitigating wind-generated vortices and wind loads near perimeter 150 .

Description
- This application claims the benefit of U.S. Provisional Patent Application No. 61/360,748, filed Jul. 1, 2010, entitled “Vortex Suppressing System,” which is hereby incorporated by reference in its entirety.
- The present disclosure relates generally to a vortex suppressing system and, more particularly, to a vortex suppressing system for a pitched roof.
- One type of roof commonly installed on buildings is a pitched roof. Pitched roofs include sloped or angled surfaces that meet at a ridge. As used herein, the term “ridge” includes a generally horizontal ridge or a sloped ridge (sometimes called a hip).
- In many instances, a pitched roof is susceptible to wind-induced damage at both its ridge(s) and perimeter. For example, the ridge area of the roof may be damaged by wind-generated vortices and upward suction loads resulting from wind-flows across the ridge. Additionally, the perimeter area of the roof may be damaged by wind-generated vortices and upward pressure loads resulting from wind-flows coming in contact with the roof perimeter and/or building surfaces positioned below the roof perimeter.
- One way to mitigate wind-induced damage to a pitched roof is to structurally strengthen the roof by, for example, using more or better fasteners to connect portions of the roof to each other and/or to the walls and/or frame of a building. Although such structural strengthening may be well-suited for new construction, it may be costly and ill-suited for retrofits of existing buildings. Moreover, structural strengthening cannot always counteract the large forces resulting from high winds of, for example, hurricanes and blizzards. Thus, even structurally strengthened pitched roofs are sometimes severely damaged and/or blown off of buildings by wind-generated vortices and upward pressure loads resulting from wind-flows.
- The disclosed systems and methods are directed to overcoming one or more of the problems set forth above and/or other problems in the art.
- In the following description, certain aspects and embodiments of the present invention will become evident. It should be understood that the invention, in its broadest sense, could be practiced without having one or more features of these aspects and embodiments. In other words, these aspects and embodiments are merely exemplary.
- The present disclosure is related to a vortex suppressing system associated with a pitched roof having sloped, generally planar first and second surfaces intersecting with one another at a roof ridge. The vortex suppressing system may include a fascia member attached to a perimeter of the roof adjacent to an edge of at least the first surface. The fascia member may extend generally outwardly away from the perimeter of the roof, and may be generally curved to define a generally arch-shaped cross-sectional shape of an outer face of the fascia member. Additionally, the vortex suppressing system may include an assembly. The assembly may include a first end portion attached to the first surface, adjacent to the roof ridge. The assembly may also include a second end portion attached to the second surface, adjacent to the roof ridge. In addition, the assembly may include a bridging portion extending over the roof ridge and from the first end portion to the second end portion. The bridging portion may have a generally curved outer surface, which may be substantially symmetrical about a plane generally parallel to the roof ridge. And, a length of the assembly may extend in generally the same direction as a length of the roof ridge.
- Aside from the arrangement set forth above, the invention could include a number of other arrangements such as those explained hereinafter. It is to be understood that both the foregoing description and the following description are exemplary only.
- The accompanying drawings are incorporated in and constitute a part of this specification. The drawings illustrate exemplary embodiments and, together with the description, serve to explain some principles of the invention. In the drawings,

- As illustrated in
FIG. 1 , anexemplary building 100 may have a pitchedroof 105 andwalls 110. For example,building 100 may be a residential, commercial, industrial, or other type of building. Regardless of the type ofbuilding 100, it is contemplated that pitchedroof 105 may include sloped, generallyplanar surfaces - The sloped, generally
planar surfaces roof ridge 130 of pitchedroof 105. This intersecting of thesurfaces surfaces roof ridge cap 135 ofroof ridge 130.Roof ridge cap 135 may overlapoutermost layers surfaces roof ridge 130.Roof ridge cap 135 optionally may include a vent to provide venting for a building space, such as an attic, belowroof 105. In some instances,roof ridge cap 135 may extend above the respective planes defined by generallyplanar surfaces - Whether or not
roof ridge 130 includesroof ridge cap 135, each ofsurfaces roof ridge 130 beyond anexterior wall 110 ofbuilding 100, and possibly also extend outwardly beyond astructural perimeter 150 of pitchedroof 105.Structural perimeter 150 comprises the outermost surfaces of the portions of pitchedroof 105 that are positioned belowsurfaces bargeboards 155,trim members 157,rafters 160, or other portions of pitchedroof 105 that are positioned belowsurfaces -
Surface 120 may extend outwardly beyond awall 110 a, andsurface 125 may extend outwardly beyond a wall 110 b. It should be understood, however, that bothsurfaces walls 110 a and 110 b, respectively. For example, in some embodiments (not shown),surface 120 orsurface 125 may extend outwardly fromroof ridge 130 toward another roof ridge (not shown) or another wall (not shown). - A
vortex suppressing system 165 may be associated with pitchedroof 105 to mitigate wind-generated vortices and wind loads nearroof ridge 130 andstructural perimeter 150. In particular,vortex suppressing system 165 may include aroof ridge assembly 170 to mitigate wind-generated vortices and wind loads nearroof ridge 130. Additionally,vortex suppressing system 165 may include one ormore perimeter assemblies 175 to mitigate wind-generated vortices and wind loads nearstructural perimeter 150. AlthoughFIG. 1 illustratesvortex suppressing system 165 as including two different types of perimeter assemblies 175 (fascia member 175 a andwindscreen 175 b, described in more detail below), it should be understood thatvortex suppressing system 165 may include only a single type ofperimeter assembly 175. Moreover, some embodiments ofvortex suppressing system 165 may include noperimeter assemblies 175. It is contemplated, however, that combining one or moreroof ridge assemblies 170 with one ormore perimeter assemblies 175 may maximize the mitigation of wind-generated vortices and wind loads nearroof 105 by mitigating wind-generated vortices and wind loads near bothroof ridge 130 andstructural perimeter 150, and thereby better protectroof 105 from potential wind damage. -
Roof ridge assembly 170 may extend in generally the same direction as a length ofroof ridge 130. When viewed along this direction, as shown inFIGS. 1-3 ,roof ridge assembly 170 may include afirst end portion 180, asecond end portion 185, and a bridgingportion 190 joiningend portions - As shown in
FIGS. 1-3 , endportions surfaces FIG. 2 , anoutermost edge 191 of a lower surface ofend portion 180 may contactsurface 120 at a distance D1 from the intersection ofsurfaces surfaces surfaces FIG. 2 , anoutermost edge 193 of a lower surface ofend portion 185 may contactsurface 125 at a distance D2 from the intersection ofsurfaces surfaces -
End portions surfaces roof ridge 130. Exemplary fastening arrangements may include adhesive, a nail, a screw, tape, a cleat, a wire, a clip, and/or other fastener. - As shown in
FIG. 3 , for example, endportions surfaces portions 195, and mounting portion(s) 195 may be attached tosurfaces fasteners 200. For example, mounting portion(s) 195 may includecleats 205 that are configured to engageend portions end portions surfaces assembly 170 may also include at least onespring member 210 extending betweenroof 105 and bridgingportion 190. Spring member(s) 210 may be configured to bias bridgingportion 190 away fromroof 105 so as to maintain engagement of mounting portion(s) 195 and at least one ofend portions roof 105, and may be deflected by bridgingportion 190 upon installation of bridging portion 190 (attachment ofend portions surfaces 120 and 125). Thus, after installation, potential energy stored in spring member(s) 210 may tend to push upward on bridgingportion 190, thereby biasing bridgingportion 190 away fromroof 105 and maintaining engagement of thecleats 205 to theend portions - In some installations of
assembly 170, mounting portion(s) 195 may be located entirely within an enclosure defined by bridgingportion 190,end portions end portion 180 andsurface 120, and betweenend portion 185 andsurface 125. Along with the enclosure, these seals may help to maintainroof 105 substantially waterproof by preventing water from reaching the areas wherefasteners 200 penetratesurfaces - In other installations of assembly 170 (not shown), mounting portion(s) 195 may be located outside of the enclosure defined by bridging
portion 190,end portions portion 190 that are perforated, for example, to enhance the vortex suppressing effect ofassembly 170 by inducing small-scale turbulence), or when mounting portion(s) 195 is/are attached tosurfaces surfaces 120 and 125 (e.g., adhesives and tapes). - Regardless of how
end portions surfaces portion 190 may extend overroof ridge 130, and may have abottom surface 215 and a generally curvedouter surface 220. Sinceroof ridge 130 may includeroof ridge cap 135, as discussed above, it should be understood that bridgingportion 190 may also extend overroof ridge cap 135. In some examples, it is contemplated thatbottom surface 215 may be spaced vertically above an uppermost part of atop surface 225 ofroof ridge 130 by a distance not larger than 25 cm. It should be noted, however, that this distance is exemplary only, and that the distance betweenbottom surface 215 andtop surface 225 may vary based on, for example, angle θ betweensurfaces - The generally curved shape of
outer surface 220 may have a relatively gradual changing slope. The configuration of theouter surface 220 alters wind flow nearroof ridge 130, and thereby mitigates wind-generated vortices and wind loads nearroof ridge 130.Outer surface 220 may be substantially symmetrical about a plane that is generally parallel toroof ridge 130. For example, as shown inFIG. 3 ,outer surface 220 is substantially symmetrical about a plane P that bisects angle θ defined bysurfaces FIG. 3 havingsurfaces surfaces outer surface 220 may allow for reduction of wind-generated vortices without being significantly impacted by the particular wind direction. However, it is contemplated thatouter surface 220 may alternatively be asymmetrical, and tailored for the specific configuration ofroof 105 nearridge 130 and/or the prevailing wind direction. - Whether or not
outer surface 220 is substantially symmetrical, it is contemplated thatouter surface 220 may define a radius of curvature not less than 3.5 cm. Like the above-discussed distances, however, it should be noted that this radius of curvature is exemplary only, and that the radius of curvature may vary alongouter surface 220 betweenend portions surfaces portion 190 may haveouter surfaces 220 including substantially flat portions 230 (referring toFIG. 4 ), which may simplify the construction ofassembly 170 and/or be visually appealing. It is contemplated that substantiallyflat portions 230 may be configured so as to avoid altering the functionality ofassembly 170. For example, substantiallyflat portions 230 may be sized and positioned such that 180°−φ, where φ is an angle between twoadjacent portions 230, never exceeds 55°. - As previously discussed,
vortex suppressing system 165 may also include afascia member 175 a. As illustrated inFIG. 5 ,fascia member 175 a may be attached toperimeter 150 via a fastening arrangement including, for example, adhesive, a nail, a screw, tape, a cleat, a wire, a clip, and/or other fastener.Fascia member 175 a extends generally outwardly away fromperimeter 150 and may be hollow or solid.Fascia member 175 a may have anouter face 400 with a generally arch-shaped cross-section, and may be positioned adjacent to surface 120. Specifically, atopmost portion 405 ofouter face 400 may be positioned adjacent to anedge 410 ofsurface 120 and spaced slightly outward from theedge 410 so that thetopmost portion 405 and edge 410 define a gap. Such positioning may allow rainwater to flow from thesurface 120 into the gap and then into achannel 412 defined by thefascia member 175 a below the gap. In addition, thetopmost portion 405 may extend vertically no higher than the plane defined by theroof surface 120. It is contemplated that the shape ofouter face 400 may alter wind flow nearstructural perimeter 150, and thereby mitigate wind-generated vortices and wind loads nearstructural perimeter 150. - Although the position of
fascia member 175 a has been described with reference tosurface 120, it should be understood thatfascia member 175 a may alternatively or additionally be positioned adjacent to surface 125 (referring toFIG. 1 ). For example, as shown inFIG. 6 ,fascia member 175 a could extend at least partially along more than one side ofperimeter 150, and be positioned adjacent to multiple sloped, generally planar surfaces of pitchedroof 105. - Regardless of the positioning of
fascia member 175 a, it is contemplated thatouter face 400 may be generally curved, but may include substantially flat portions 415 (referring toFIG. 7 ) and/or step portions 420 (referring toFIG. 8 ). Substantiallyflat portions 415 and stepportions 420 may be visually appealing, and may be sized so as to avoid altering the functionality offascia member 175 a. For example, substantiallyflat portions 415 may be sized and positioned such that 180°−α, where α is an angle between twoadjacent portions 415, never exceeds 55°. And, generallyvertical parts 425 ofstep portions 420 may be sized such that their vertical heights do not exceed 25% of the total vertical height H offascia member 175 a. These arrangements may generate small-scale eddies or turbulences that help mitigate generation or formation of larger scale vortices, which might otherwise cause severe uplift wind loads onroof 105 nearedge 410. - As previously discussed, instead of or in addition to
fascia member 175 a,vortex suppressing system 165 may include awindscreen 175 b. As illustrated inFIG. 9 ,windscreen 175 b may include mounting portion(s) 430, ascreen portion 435, and anintermediate channel portion 440 joining mounting portion(s) 430 to screenportion 435. - Mounting portion(s) 430, which may be shaped to conform to
perimeter 150, may be attached toperimeter 150 by any type of fastening arrangement, which may include, for example, adhesive, a nail, a screw, tape, a cleat, a wire, a clip, and/or other fastener. As shown inFIG. 9 , for example,fasteners 445 may be used to attach mounting portion(s) 430 toperimeter 150. - Regardless of how mounting portion(s) 430 is/are attached to
perimeter 150, it is contemplated thatwindscreen 175 b may be positioned such that thescreen portion 435 extends generally laterally and outwardly away fromperimeter 150 with at least a portion ofscreen portion 435 being substantially coplanar withsurface 125 of pitchedroof 105. For example, a part oftop surface 450 ofscreen portion 435 may be substantially coplanar withsurface 125, and may extend fromintermediate channel portion 440 to afree end 455 ofscreen portion 435. It is contemplated that an end part ofscreen portion 435, which includesfree end 455, may bend and/or extend generally downward from the plane defined byroof surface 125. Alternatively, the end part ofscreen portion 435 may be substantially coplanar withsurface 125. -
Screen portion 435 is configured to alter wind flow nearperimeter 150. For example,screen portion 435 may include perforations 460 (referring toFIG. 10A ), serrations 465 (referring toFIG. 10B ), or bothperforations 460 and serrations 465 (referring toFIG. 10C ). -
FIG. 10A illustrates oneembodiment including perforations 460. It should be understood, however, that the layout, shapes, and sizes ofperforations 460 may vary based on, for example, aesthetic considerations and/or manufacturing costs. The open area of thescreen portion 435, i.e., the entire area occupied by the open space of theperforations 460 as compared to the total area of top surface 450 (including the solid surface area and the area occupied by the open space of the perforations 460), may range from about 25% to about 75%, e.g., from about 35% to about 65%, and may be about 50%. It is contemplated that pressures on opposite surfaces ofscreen portion 435 may equalize viaperforations 460, thereby mitigating wind-generated vortices and wind loads nearstructural perimeter 150. - As illustrated in
FIGS. 10B and 10C ,free end 455 may includeserrations 465, which may be semi-circular (referring toFIG. 10B ) or triangular (referring toFIG. 10C ). Alternatively,serrations 465 may be square, semi-elliptical, or otherwise shaped. Although allserrations 465 offree end 455 may be the same size and shape, it is contemplated that some embodiments may includeserrations 465 of varying size and/or shape. Moreover, it is contemplated that a layout ofserrations 465 may also vary. For example,serrations 465 having different shapes could be laid out in a particular order or could be randomly distributed alongfree end 455. It is contemplated thatserrations 465 may disorganize air flow overfree end 455, thereby mitigating wind-generated vortices and wind loads nearperimeter 150. - As previously discussed, mounting portion(s) 430 and
screen portion 435 may be joined byintermediate channel portion 440. As illustrated inFIG. 9 ,intermediate channel portion 440 may be generally “V” shaped. Upon installation ofwindscreen 175 b, it is contemplated that the “V” shape may be oriented with its opening facing generally upwards. Further, it is contemplated thatintermediate channel portion 440 may be positioned adjacent to edge 470 ofsurface 125, and below a gap defined by theedge 470 and aninner end 472 of thescreen portion 435. Such positioning may allow rainwater to flow fromsurface 125, into the gap and then intochannel portion 440. In some embodiments, drain holes (not shown) may be provided inchannel portion 440. It is contemplated thatchannel portion 440 may protect an underside ofoutermost layer 145 from upward wind flow and pressure. - Although the position of
windscreen 175 b has been described with reference tosurface 125, it should be understood thatwindscreen 175 b may alternatively or additionally be positioned adjacent to surface 120 (referring toFIG. 1 ). For example, as shown inFIG. 11 ,windscreen 175 b could extend at least partially along more than one side ofperimeter 150, withwindscreen 175 b being positioned adjacent to multiple sloped, generally planar surfaces of pitchedroof 105. - Some embodiments of
windscreen 175 b may not includeintermediate channel portion 440. In these embodiments, mounting portion(s) 430 may be joined directly toscreen portion 435, as illustrated inFIG. 12 , and aninnermost part 475 ofscreen portion 435 may be positioned slightly below outermost layer(s) 140 and/or 145 ofsurfaces screen portion 435, and off ofbuilding 100. - Regardless of what
assemblies vortex suppressing system 165 includes, it is contemplated thatvortex suppressing system 165 may be installed during initial construction ofbuilding 100 and/or during a retrofit of a previously constructed building 100 at some later date. In either case, for example,roof ridge assembly 170 may be installed overroof ridge 130 to suppress wind-generated vortices and wind loads nearroof ridge 130. In particular, the installation ofassembly 170 may include attachingend portions surfaces roof ridge assembly 170,fascia member 175 a and/orwindscreen 175 b may be installed to suppress wind-generated vortices and wind loads nearperimeter 150. For example, the installation offascia member 175 a and/orwindscreen 175 b may include attachingfascia member 175 a and/orwindscreen 175 b toperimeter 150 using any of the fastening arrangements discussed above. - It is contemplated that the installation of
vortex suppressing system 165 may redefine the exterior shape of pitchedroof 105 while maintaining the architectural characteristics ofroof 105. The redefined shape may prevent accelerated wind-flows acrossroof ridge 130 and/orperimeter 150. Such modification of the wind-flows may prevent and/or reduce the strength of wind vortices and/or wind loads nearroof ridge 130 and/orperimeter 150, thereby minimizing cyclic loads on components ofroof 105 resulting from recurring winds, and reducing the chances of damage due to material fatigue. - The embodiments and aspects of the invention described above are not restrictive of the invention as claimed. Other embodiments consistent with the above-discussed features and principles are included in the scope of the present invention. For example, embodiments including one or more features disclosed in U.S. Pat. No. 7,487,618 in its drawing figures, and in column 3, line 39, to column 4, line 45; column 4, line 62, to column 5, line 17; and column 5, line 40, to column 6, line 12, which are incorporated herein by reference, are included in the scope of the present invention. Additionally, embodiments including one or more features disclosed in U.S. Patent Application Publication No. 2006/0016130 in its drawing figures, and in paragraphs [0025]-[0029] and [0031]-[0033], which are incorporated herein by reference, are included in the scope of the present invention.
- In the foregoing description, various features are grouped together for purposes of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects may relate to fewer than all features of any particular embodiment disclosed herein.
