Definitions
- the present disclosure generally relates roofing trim panels and, in particular, to roofing trim panels for concealing a biocidal source
- biocidal sources are often in the form of a strip that includes or is formed of a biocidal material, such as copper, zinc, lead, or the like.
- the biocidal source is generally installed at or below the ridge line of a roof. Water (e.g., rain water) flowing across the biocidal source will dissolve or otherwise entrain part of the biocidal material therein, and carry the biocidal material over shingles or other roofing material that is below the biocidal source.
- water flowing over the biocidal source will entrain copper, zinc, and/or lead ions therein.
- the copper, zine, and/or lead ions will be conveyed by the flow over water over shingles or other roofing material below the biocidal source—scattering such ions over the roof. Those ions can act to limit or prevent unwanted biological growth on the roof downstream of the biocidal source.
- biocidal sources can be unsightly.
- Many biocidal sources are in the form of a metallic strip that does not blend in with the aesthetic of roofing materials such as shingles.
- the metals used in many biocidal sources may also oxidize over time, making them even more unsightly.
- Many property owners therefore do not wish to employ biocidal sources on their roof, particularly as a thick strip or multiple strips of biocidal material are often needed to adequately cover a substantial surface area of a roof.
- ridge vent systems that incorporate a biocidal source therein have been developed.
- such systems utilize the structure of a ridge vent to conceal the biocidal source from view, while still allowing rain water to flow over the biocidal material.
- Such solutions can effectively hide biocidal sources from view, they can be difficult and/or expensive to install in a pre-existing roof (i.e., to install on a pre-existing building).
- Such solutions may also use a modified ridge vent design.
- ridge vents are often readily observable features of a building, property owners may notice and object to even small changes to their design, relative to a “traditional” ridge vent design.
- the inventors have identified that there is a need in the art for a roofing trim panel that can shield a biocidal source from view, is relatively easy to install on a pre-existing roof, and which retains much or all the aesthetic quality of a roof.
- the technologies of the present disclosure aim to address that need.

- proximate may be used to denote the relative position of one (first) element to another (second) element.
- proximate should be understood to mean that the first element is near the second element, but is not necessarily immediately adjacent the second element.
- perpendicular and “parallel” are used herein to describe the orientation of one (first) element to another (second) element.
- perpendicular means that a first element extends in a first direction/plane, and a second element extends at right angle to the first direction/plane.
- parallel means that a first element extends in a first direction/plane, and a second element extends along a plane that is offset from the first direction/plane but which extends along the first direction or plane.
- the terms “substantially” and “about” may be used in connection with an identified value, range, or orientation. In the context of a value or a range, such terms mean+/ ⁇ 10% of the indicated value or range. In the context of an orientation such terms mean that one component is oriented within +/ ⁇ 10% of the indicated orientation. Thus, “substantially 10” or “about 10” means 9 to 11. Similarly, “substantially perpendicular” means that a second element is oriented perpendicular to a first element or within +/ ⁇ 10 degrees of perpendicular to the first element. Likewise, “substantially parallel” means that a second element is oriented parallel to a first element or within +/ ⁇ 10 degrees of parallel to the first element.
- the present disclosure generally relates to roofing panels, and particularly to roofing panels for concealing a biocidal source.
- the roofing panels of the present disclosure can effectively conceal biocidal sources such as metallic strips from view, while retaining much or all of the aesthetic appeal of the adjacent roofing.
- the roofing panels described herein are also relatively easy to install on a pre-existing home, and do not (or do not substantially affect) performance of the biocidal source.

For example, bacteria, fungus, plant life (e.g. moss), etc. (individually and collectively, “biological growth”) can grow on shingled roofs, negatively affecting the aesthetic qualities of the roof and potentially causing damage thereto.
- Roofers and other skilled artisans often place a biocidal source on a roof to mitigate or prevent biological growth thereon. Such biocidal sources are often in the form of a strip that includes or is formed of a biocidal material, such as copper, zinc, lead, or the like. The biocidal source is generally installed at or below the ridge line of a roof. Water (e.g., rain water) flowing across the biocidal source will dissolve or otherwise entrain part of the biocidal material therein, and carry the biocidal material over shingles or other roofing material that is below the biocidal source. For example when the biocidal material is or includes copper, zinc, and/or lead, water flowing over the biocidal source will entrain copper, zinc, and/or lead ions therein. The copper, zine, and/or lead ions will be conveyed by the flow over water over shingles or other roofing material below the biocidal source—scattering such ions over the roof. Those ions can act to limit or prevent unwanted biological growth on the roof downstream of the biocidal source.
- Although effective, biocidal sources can be unsightly. Many biocidal sources are in the form of a metallic strip that does not blend in with the aesthetic of roofing materials such as shingles. The metals used in many biocidal sources may also oxidize over time, making them even more unsightly. Many property owners therefore do not wish to employ biocidal sources on their roof, particularly as a thick strip or multiple strips of biocidal material are often needed to adequately cover a substantial surface area of a roof.
- Various systems and methods have been developed over the years to address the poor aesthetic quality of biocidal sources. For example, several ridge vent systems that incorporate a biocidal source therein have been developed. Generally, such systems utilize the structure of a ridge vent to conceal the biocidal source from view, while still allowing rain water to flow over the biocidal material. Although such solutions can effectively hide biocidal sources from view, they can be difficult and/or expensive to install in a pre-existing roof (i.e., to install on a pre-existing building). Such solutions may also use a modified ridge vent design. As ridge vents are often readily observable features of a building, property owners may notice and object to even small changes to their design, relative to a “traditional” ridge vent design.
- With the foregoing in mind, the inventors have identified that there is a need in the art for a roofing trim panel that can shield a biocidal source from view, is relatively easy to install on a pre-existing roof, and which retains much or all the aesthetic quality of a roof. The technologies of the present disclosure aim to address that need.

In that context, the term “proximate” should be understood to mean that the first element is near the second element, but is not necessarily immediately adjacent the second element.
- The terms “perpendicular,” and “parallel” are used herein to describe the orientation of one (first) element to another (second) element. The term “perpendicular” means that a first element extends in a first direction/plane, and a second element extends at right angle to the first direction/plane. In contrast, the term “parallel” means that a first element extends in a first direction/plane, and a second element extends along a plane that is offset from the first direction/plane but which extends along the first direction or plane.
- As used herein, the terms “substantially” and “about” may be used in connection with an identified value, range, or orientation. In the context of a value or a range, such terms mean+/−10% of the indicated value or range. In the context of an orientation such terms mean that one component is oriented within +/−10% of the indicated orientation. Thus, “substantially 10” or “about 10” means 9 to 11. Similarly, “substantially perpendicular” means that a second element is oriented perpendicular to a first element or within +/−10 degrees of perpendicular to the first element. Likewise, “substantially parallel” means that a second element is oriented parallel to a first element or within +/−10 degrees of parallel to the first element.
- As explained in the background, various systems have been developed for concealing a biocidal source mounted to a roof. While such systems can effectively conceal a biocidal source from view (particularly from the ground), they are not without some disadvantages. For example, such systems may be difficult and/or expensive to install with a pre-existing homes, and thus are most suitable for use with new construction. Such systems may also rely on modifications to traditional ridge vent design, resulting in an installation that may also be aesthetically unappealing to some observers.
- With the foregoing in mind, the present disclosure generally relates to roofing panels, and particularly to roofing panels for concealing a biocidal source. As will become apparent, the roofing panels of the present disclosure can effectively conceal biocidal sources such as metallic strips from view, while retaining much or all of the aesthetic appeal of the adjacent roofing. The roofing panels described herein are also relatively easy to install on a pre-existing home, and do not (or do not substantially affect) performance of the biocidal source.

FIGS. 1A-1Z depict various views of one example of a roofing panel consistent with the present disclosure. As best shown inFIGS. 1A, 1D, 1F and 1I ,roofing panel 100 includes body with atop side 101, abottom side 103 parallel withtop side 101, afront edge 105, arear edge 107, aleft edge 109, and aright edge 111. For clarity and ease of understanding, the present disclosure focused on embodiments in which the body ofroofing panel 100 has a generally rectangular shape (i.e., in which leftedge 109 is parallel toright edge 111 andfront edge 105 is parallel to rear edge 107) but that configuration is not required. Indeed, the present disclosure encompasses embodiments in which the body ofroofing panel 100 has any suitable geometric or irregular shape. In embodiments, the body ofroofing panel 100 has a geometric shape with a plurality of sides, wherein the number of sides ranges from 3, 4, 5, 6, 7, 8, 9, or more. For example, the body may have a generally triangular, square, rectangular, trapezoidal, pentagonal, hexagonal, etc. shape. That being said, the embodiment ofFIGS. 1A-1Z includes a body with four edges (sides) and a generally rectangular profile as it is configured for use with roofing (e.g., shingles) that has a quadrilateral (e.g., square, rectangular, etc.) shape. - As further shown in various FIGS.,
roofing panel 100 also includes afirst sidewall 113 and asecond sidewall 115. First andsecond sidewalls left side 113” and “right side 115,” as they are illustrated on those sides of the embodiment ofroofing panel 100 depicted inFIGS. 1A-1Z . The roofing panels described herein are not limited to the illustrated configuration, however, and the features offirst sidewall 113 andsecond sidewall 115 may be reversed. That is, features ofsecond sidewall 115 may be used onfirst sidewall 113, and vice versa. -
First sidewall 113 andsecond sidewall 115 each extend from thebottom side 103 of the body ofroofing panel 100. In embodiments and as best shown inFIGS. 1B, 1F , and 1G,first sidewall 113 andsecond sidewall 115 are each preferably oriented perpendicular or substantially perpendicular to the body ofroofing panel 100 or, more particularly, tobottom side 103. In any case,first sidewall 113 includes a first sidewalldistal end 151 and a first sidewallproximal end 153. In the illustrated embodiment and as best shown inFIGS. 1F and 1Q , first sidewalldistal end 151 is located proximate torear edge 107, and first sidewallproximal end 153 is located proximate tofront edge 105. Similarly,second sidewall 115 includes a second sidewalldistal end 155 and a second sidewallproximal end 157. As best shown inFIGS. 1G and 1V , second sidewalldistal end 155 is located proximate torear edge 107, and second sidewallproximal end 157 is located proximate tofront edge 105. - In embodiments and as best shown in
FIGS. 1Q and 1V ,first sidewall 113 andsecond sidewall 115 may each have a generally quadrilateral (e.g., trapezoidal) shape when viewed from a side ofroofing panel 100. Such a configuration is not required, however, andfirst sidewall 113 andsecond sidewall 115 may have any suitable shape when viewed from a side ofroofing panel 100. For example, first andsecond sidewalls - First and
second sidewalls FIGS. 1Q and 1V . In such embodiments and as shown inFIG. 1Q , the first sidewalldistal end 151 may extend from apoint 193 at an intersection withrear edge 107 to apoint 194 on a lower edge offirst sidewall 113 that extends beyondrear edge 107. That is, the first sidewalldistal end 151 may extend at an angle betweenpoints point 194 is laterally offset frompoint 193 by a distance D1. More specifically, in such embodiments the angle between first sidewalldistal end 151 andtop side 101 may be greater than or equal to 90 degrees, such as between 90 and 130 degrees. Similarly and as shown inFIG. 1V , in such embodiments the second sidewalldistal end 155 may extend from apoint 197 at an intersection withrear edge 107 to apoint 198 on a lower edge ofsecond sidewall 115 that extends beyondrear edge 107. That is, the second sidewalldistal end 155 may extend at an angle betweenpoints point 198 is laterally offset frompoint 197 by a distance D2, where D2 is the same or different from D1. More specifically, in such embodiments the angle between second sidewalldistal end 155 andtop side 101 may be greater than or equal to 90 degrees, such as between 90 and 130 degrees. In embodiments, D1 equals or substantially equals D2. - When first and second sidewall distal ends 151, 155 are configured in the manner shown in
FIGS. 1A-1Z , the distance D1 and D2 may be selected to provide a gap between roofing panel 100 (or, more specifically,standoffs 117 described below) and roofing that's located above (i.e., upstream) ofroofing panel 100. As will become apparent, whenroofing panel 100 is installed on a roof and over a biocidal source, that gap can provide a mechanism to allow water or other fluid to flow into one or more channels betweenstandoffs 117 and over the biocidal source. In non-limiting embodiments D1 and D2 each range from greater than 0 to about 2 inches (50.8 millimeters (mm)), such as from about 0.25 to about 1 inches (6.4 to 25.4 (mm)). - Of course, the present disclosure is not limited to embodiments in which first and second sidewall distal ends 151, 155 are configured as shown in
FIGS. 1A-1Z . For example, in embodiments first and/or second sidewall distal ends are configured such thatpoint 194 is disposed directly belowpoint 193, andpoint 198 is disposed directly belowpoint 197, in which case D1 and/or D2 equals zero. In those embodiments, the height of the first and second sidewall distal ends 151, 155 (i.e., the distance betweenpoints points 197 and 198) may be set such thatpoints roofing panel 100, thus allowing fluid to flow into channels between one ormore standoffs 117, as described later. - As also shown in
FIG. 1Q , the first sidewallproximal end 153 may extend from apoint 158 at an intersection between an upper side offirst sidewall 113 and first sidewallproximal end 153 to apoint 159 at an intersection between alower side 163 offirst sidewall 113 and first sidewallproximal end 153. In the illustrated embodiment, first sidewallproximal end 153 is oriented at a less than 90 degree angle (e.g., less than 90 degrees to about 45 degrees) relative to the top surface offirst sidewall 113, such thatpoint 158 is laterally offset frompoint 159. - Similarly and as shown in
FIG. 1V , second sidewallproximal end 157 may extend from apoint 160 at an intersection of an upper side ofsecond sidewall 115 with second sidewallproximal end 157 to apoint 161 at an intersection of alower side 165 ofsecond sidewall 115 and second sidewallproximal end 157. That is, the second sidewallproximal end 157 may extend at a less than 90 degree angle (e.g., less than 90 degrees to about 60 degrees) betweenpoints point 160 is laterally offset frompoint 161. More specifically, in such embodiments the angle between second sidewalldistal end 155 andtop side 101 may be greater than or equal to 90 degrees, such as between 90 and 130 degrees. In embodiments, D1 equals or substantially equals D2. - Of course, the present disclosure is not limited to embodiments in which first and second sidewall proximal ends 153, 157 are configured as shown in
FIGS. 1A-1Z . In embodiments, first and/or second sidewall proximal ends 153, 157 are flat and are configured such thatpoint 159 is disposed directly belowpoint 158 andpoint 161 is disposed directly belowpoint 160. In such instances, first sidewallproximal end 153 may be oriented perpendicular or substantially perpendicular to the lower side offirst sidewall 113, and second sidewallproximal end 157 may be oriented perpendicular or substantially perpendicular to the lower side ofsecond sidewall 115. - As further shown in
FIGS. 1Q and 1V , first andsecond sidewalls rear edge 107, and is relatively thin nearfront edge 105. More specifically, first andsecond sidewalls rear edge 107 to a front height (HF) proximatefront edge 105. While the present disclosure focuses on embodiments wherein the first and second sidewall heights mirror one another (i.e., taper from HR to HF in the same manner), such a configuration is not required, and the first and second sidewall heights may differ from one another as desired. - As shown in
FIG. 1Q , the rear height HV offirst sidewall 113 is defined as the shortest distance between apoint 193 of intersection betweenfirst sidewall 113 andrear edge 107, andlower side 163 offirst sidewall 113. Likewise as shown inFIG. 1V , the rear height HV ofsecond sidewall 115 is defined as the shortest distance between apoint 197 of intersection betweensecond sidewall 115 andrear edge 107, andlower side 165 ofsecond sidewall 115. In embodiments where D1 is zero and first sidewall distal end is flat, HR offirst sidewall 113 is the same as the length of first sidewalldistal end 151. Likewise when D2 is zero and second sidewalldistal end 155 is flat, HR ofsecond sidewall 115 is the same as the length of second sidewalldistal end 155. In any case, the HR of the first andsecond sidewalls second sidewalls - As shown in
FIGS. 1R and 1T , the front height HFfirst sidewall 113 is defined as the shortest distance between apoint 195 at an intersection offront edge 105 andfirst sidewall 113 andlower side 163 offirst sidewall 113. Likewise and as shown inFIGS. 1W and 1Y , the front height HF ofsecond sidewall 115 is defined as the shortest distance between apoint 199 at an intersection offront edge 105 andsecond sidewall 115 andlower side 165 ofsecond sidewall 115. - As noted above the first sidewall height and second sidewall height may taper from HR to HF in the same or different manner. In embodiments the first and second sidewall heights taper in the same manner (i.e., mirror one another), such that first and
second sidewalls first sidewall 113 andlower side 163 may equal the distance (height) at corresponding points along an upper edge ofsecond sidewall 115 andlower side 165. Preferably, the first and second sidewall heights taper in the same manner, and taper linearly between HR to HF. - As will be discussed below, features such as one or more coupling elements may be coupled to or integral with first and
second sidewalls female coupling elements first sidewall 113, and one or moremale coupling elements second sidewall 115. In such instances, the first and second sidewall height refers to the distance between a straight line projected along an upper edge of thefirst sidewall 113 or thesecond sidewall 115, and a straight line projected along an edge of the correspondinglower side points points FIG. 1Q . Likewise, in such instances the second sidewall height refers to the distance between a straight line projected betweenpoints points FIG. 1V . In either case, the projected straight lines pass across any gaps, depressions, etc. and/or through any features that may be present on or within first andsecond sidewalls - In embodiments, HR and HF are selected such that a space is present between
bottom side 103 and roofing or a biocidal source disposed belowroofing panel 100 whenroofing panel 100 is installed. More specifically, whenroofing panel 100 is installed on a roof,lower sides second sidewalls bottom side 103 and the underlying roofing/biocidal source proximate rear edge 107 (i.e., on an upstream side of roofing panel 100) as shown inFIGS. 1K and 1U . Likewise, HF may be selected to provide a space (i.e., a gap G2) between thebottom side 103 and the underlying roofing/biocidal source proximate front edge 105 (i.e., on a downstream side of roofing panel 100), as shown inFIG. 1T . In operation, water flowing down the roof may enter into the space G1 provided by HR ((and/or one ormore standoffs 117, as described later) on the upstream side of roofing panel 100 (i.e., proximate rear edge 107), and may flow downwards (over the underlying roofing and/or biocidal source) towardsfront edge 105. Ultimately, the water may emerge from the space G2 provided by HF (and/or one or moretapered spacers 119, described later) and continue to flow downstream ofroofing panel 100. - HR and HF may be any suitable height, provided they are greater than 0. In embodiments, HR and HF are the same (in which case first and
second sidewalls - In the illustrated embodiments and as best shown in
FIGS. 1S and 1X , first andsecond sidewalls front edge 105. More specifically and as shown inFIG. 1S , first sidewallproximal end 153 may extend pastfront edge 105 by an offset distance O1. Likewise and as shown inFIG. 1X , second sidewallproximal end 157 may extend pastfront edge 105 by an offset distance O2, which may be the same or different from O1. In embodiments O1 and O2 are the same, and are selected such that the distance between first and second sidewall proximal ends 153, 157 (or an abutment surface of aroofing retention element 141 thereon) andrear edge 107 is about the same as one or more dimensions of a roofing material to be installed ontop side 101. With that in mind, the distance between first and second sidewall proximal ends 153, 157 (or an abutment surface of aroofing retention element 141 thereon) andrear edge 107 may range from about 2 to about 12 inches or more. Without limitation, in embodiments the distance between first and second sidewall proximal ends 153, 157 (or an abutment surface of aroofing retention element 141 thereon) andrear edge 107 is about 4 to about 8 inches, such as about 6 inches. Such distance may correspond to a width or length of a profile portion of a standard roofing shingle. - As mentioned above, when
roofing panel 100 is installed on a roof, roofing (e.g., one or more roofing shingles) may be coupled to the top oftop side 101 so as to conceal roofing panel from view. Such roofing may be coupled to thetop side 101 in any suitable manner, such as via an adhesive, one or more mechanical fasteners, or a combination thereof. Preferably, roofing such as a roofing shingle is coupled totop side 101 via an adhesive. IN such instances,roofing panel 100 may include one or more features that maintain the position of roofing that is applied totop side 101 with an adhesive until the adhesive cures. More specifically and as shown in various FIGS.,roofing panel 100 may include one or moreroofing retention elements 141. When used,roofing retention elements 141 may be positioned at any suitable location for retaining and/or aligning roofing on thetop side 101 ofroofing panel 100. In the embodiment ofFIGS. 1A-1Z ,roofing retention elements 141 are coupled to or integral with an upper side of first andsecond sidewalls roofing retention elements 141 may also be disposed on an upper side of one or moretapered spacers 119, which are described in further detail below. - In the illustrated embodiment,
roofing retention elements 141 include a generally flat abutment surface that is oriented to facefront edge 105 and/orrear edge 107, and a curvilinear surface that is oriented away fromfront edge 105 and/orrear edge 107. In use, the abutment surface may abut an edge of roofing applied totop side 101. Asroofing panel 100 will typically be installed on a roof withfront edge 105 belowrear edge 107, movement of roofing applied totop side 101 may be limited and/or prevented by the interaction of the relatively flat abutment surface of theroofing retention elements 141 and an edge of the roofing. - Although the
roofing retention elements 141 are useful in the illustrated configuration, the present disclosure is not limited thereto. Indeed, the present disclosure encompasses embodiments in whichroofing retention elements 141 are of any suitable shape, and include 1 or more abutment surfaces of any suitable configuration. For example,roofing retention elements 141 may be in the form of a geometric or irregular shaped post having one or more sides (e.g., a circular post, triangular post, quadrilateral post, pentagonal post, star shaped post, etc.), wherein the post is coupled to or is integral with an upper side of first andsecond sidewalls tapered spacer 119. Alternatively or additionally,roofing retention elements 141 may be in the form of a hook or barb that is coupled to or integral with an upper side of first andsecond sidewalls tapered spacer 119. -
Roofing panel 100 further includes a plurality ofstandoffs 117, as shown inFIGS. 1A-1C, 1H-1P, 1S, 1U -X, and 1Z. As best shown inFIGS. 1C, 1K, 1N, 1P, 1U, and 1Z standoffs 117 each extend from (i.e., are coupled to or are integral with)bottom side 103 of the body ofroofing panel 100, and include a standoffdistal end 118. In the illustrated embodiment standoffdistal end 118 is oriented substantially in parallel with first and second sidewall distal ends 151, 155, such that each standoffdistal end 118 lies in substantially the same plane as first and second sidewall distal ends 151, 155. Moreover, in the illustrated embodiment eachstandoff 117 has a standoff height (between a point at the intersection between a sidewall ofstandoff 117 andbottom side 103 and a corresponding point at the intersection between the same sidewall ofstandoff 117 and lower side 166), wherein the standoff height is the same or substantially the same as the gap G1 provided by first andsecond sidewalls lower side 166 of astandoff 117 lies in the same or substantially the same plane as a corresponding point alonglower sides second sidewalls embodiment standoffs 117 are configured to maintain the gap G1 between thebottom side 103 and material (e.g., roofing or a biocidal source) underlyingroofing panel 100 whenroofing panel 100 is installed. - The number of
standoffs 117 used is not limited, and any suitable number of standoffs may be used. For example, the number ofstandoffs 117 may be 0 (in which case standoffs 117 are optional), or greater than 0. When greater than 0, the number ofstandoffs 117 may range from 1 to 1000 or more, such as from 1 to 500, 1 to 100, or 1 to 50. In embodiments, the number ofstandoffs 117 that are used depends on the distance between an inward facing side of first andsidewalls standoffs 117, and the spacing betweenadjacent standoffs 117 and/or astandoff 117 and an inward facing side offirst sidewall 113 orsecond sidewall 115. In embodiments, the number ofstandoffs 117 is selected to adequately support therear edge 107 ofroofing panel 100, i.e., to limit or prevent sagging ofrear edge 107 betweenfirst sidewall 113 andsecond sidewall 115. - In embodiments and as shown in
FIG. 1K , a plurality ofstandoffs 117 are used and eachstandoff 117 is spaced from anadjacent standoff 117 by standoff spacing S, so as to define a channel there between. Standoff spacing S is not limited provided it allows for sufficient flow of water through the channel between adjacent standoffs, and/or between a standoff and an adjacent first orsecond sidewall -
Standoffs 117 may have any suitable thickness, and one or more sides. In embodiments, the thickness of standoffs ranges from greater than 0 to about 1 inch, such as greater than 0 to about 0.5 inches, greater than 0 to about 0.25 inches, or even greater than 0 to about 0.125 inches. Preferably, the thickness ofstandoffs 117 in is in the range of greater than 0 to about 0.25 inches. -
Standoffs 117 may also include one or more sides, as shown in various FIGS. In the illustrated embodiments,standoffs 117 each have a first standoff side and a second standoff side, wherein the first and second standoff sides have a quadrilateral (e.g., trapezoidal) shape that is substantially the same as a corresponding portion offirst sidewall 113,second sidewall 115, or both.Standoffs 117 are not limited to that configuration, however, and may include sides that are any suitable geometric or irregular shape. For example, the sides ofstandoffs 117 may have a triangular, quadrilateral (square, rectangular, trapezoidal, etc.), pentagonal, hexagonal, or other geometric or irregular shape. - In embodiments and as shown in
FIG. 1S ,standoffs 117 further include a standoffproximal end 120, which in the illustrated embodiments is located betweenrear edge 107 andfront edge 105 of the body ofroofing panel 100. That configuration is not required, however, and standoffproximal end 120 may be at any suitable position betweenrear edge 107 andfront edge 105, or pastfront edge 105. In some embodiments, one ormore standoffs 117 extend to or pastfront edge 105 of the body ofroofing panel 100, such that standoffproximal end 120 is located pastfront edge 105. In such instances, such standoffs may form one or moretapered spacers 119, as shown inFIGS. 1B, 1C, 1H, 1I, 1M, 1N, 1Y, and 1Z . - Generally, tapered
spacers 119 include the same or similar features asstandoffs 117. That is, likestandoffs 117, tapered spacers extend from or are coupled tobottom side 103, and include a (tapered spacer) distal end, a (tapered spacer) proximal end, and a (tapered spacer) lower surface).Tapered spacers 119 differ from standoffs in that they have a spacer height that mirrors the first sidewall height and/or second sidewall height, and in that they extend such that their proximal end is located at or pastfront edge 105. For example and as shown in the illustrated embodiment, tapered spacers have a spacer height that tapers from HR to HF in the same or substantially the same manner as the first and second sidewall heights described above. Moreover, the proximal end of eachtapered spacer 119 extends pastfront edge 105 by a distance that is the same or substantially the same as offset distance O1 and/or O2 (or both O1 and O2, when such distances are the same). -
Tapered spacers 119 also differ in function fromstandoffs 117. As noted above,standoffs 117 are configured to supportrear edge 107 and maintain a gap between thebottom side 103 of the body ofroofing panel 100 and materialunderlying roofing panel 100 when it is installed. In contrast, taperedspacers 119 are configured to support and/or stiffen the body ofroofing panel 100, e.g., by supportingbottom side 103 fromrear edge 107 tofront edge 105, or vice versa. - As further shown in various FIGS.,
roofing panel 100 may further include one or a plurality ofreinforcements 121. In the illustrated embodiments,reinforcements 121 are in the form of four serpentine walls that extend frombottom side 103, and which extends between and is coupled tofirst sidewall 113 andsecond sidewall 115. In that configuration, eachreinforcement 121 has a reinforcement height (R4, R3, R2, R1), that is less than the sidewall height measured at a point of intersection between areinforcement 121 andfirst sidewall 113 andsecond sidewall 115, respectively. Thus, the height of the reinforcements decrease with increasing proximity tofront edge 105, and increases with increase proximity torear edge 107. For example and as shown inFIG. 1S , height R4 of areinforcement 121 located proximate torear edge 107 is greater than a height R3 of areinforcement 121 located further away fromrear edge 107, which is greater than a height R2 of areinforcement 121 located even further away fromrear edge 107, which is greater than a height R1 of areinforcement 121 located still further away from rear edge 107 (i.e., R4>R3>R2>R1). In such instances, R1-R4 may be less than the first and second sidewall height, and may range from greater than 0 to about 2.5 inches, such as from greater than 0 to about 1.5 inches, greater than 0 to about 1 inches, greater than 0 to about 0.75 inches, greater than 0 to about 0.5 inches, greater than 0 to about 0.25 inches, or even greater than 0 to about 0.125 inches. Without limitation, in embodiments R1-R4 are each in the range of 0.25 to 0.75 inches, where R4>R3>R2>R1. - Of course, the present disclosure is not limited to the use of reinforcements that are configured in the manner illustrated in
FIGS. 1A-1Z . Indeed, the present disclosure encompasses embodiments in whichreinforcements 121 have any suitable shape and/or height. For example,reinforcements 121 may be in the form of a straight wall, a lattice of interconnected walls (e.g., two linear walls coupled by a plurality of intersecting lattice walls), rounded edge walls, combinations thereof, and the like. Moreover,reinforcements 121 may be of any height, so long as their height is less than or equal to the first and/or second sidewall height at a corresponding point along first andsecond sidewalls 113, 115 (i.e., measured at a point at which the reinforcement contacts the sidewall, or measured at a point on the first or second sidewall that is intersected by a line projected from a point on areinforcement 121 that is closest to therespective sidewall - In the illustrated embodiment tapered
spacers 119 may contact one or more ormore reinforcements 121. For example and as best shown inFIG. 1C , tapered spacers may pass or otherwise extend through one ormore reinforcements 121 as they extend betweenrear edge 107 andfront edge 105. In some instances,reinforcements 121 are divided into segments, wherein each segment extends between twotapered spacers 119, and or between atapered spacer 119 and one offirst sidewall 113 andsecond sidewall 115. In such instances,reinforcement 121 may have a length corresponding to the spacing between two sequentialtapered spacers 119, or atapered spacer 119 and one offirst sidewall 113 orsecond sidewall 115. In that regard, the spacing between sequentialtapered spacers 119 and/or between atapered spacer 119 andfirst sidewall 113 orsecond sidewall 115 is not limited, and any suitable spacing may be used. In embodiments, the spacing between sequentialtapered spacers 119 and/or between atapered spacer 119 andfirst sidewall 113 orsecond sidewall 115 ranges from greater than 0 to about 16 inches, such as from greater than 0 to about 12 inches, from greater than 0 to about 10 inches, from greater than 0 to about 8 inches, from greater than 0 to about 6 inches, from greater than 0 to about 4 inches, or even from greater than 0 to about 2 inches. Of course, larger or smaller spacing between such elements may also be used. In embodiments, the spacing between sequentialtapered spacers 119 and/or between atapered spacer 119 andfirst sidewall 113 orsecond sidewall 115 is about 4 to about 8 inches. - As further shown in various FIGS.,
roofing panel 100 may further include one or a plurality ofshort spacers 123. As best shown inFIGS. 1B, 1C, and 1S , eachshort spacer 123 extends frombottom side 103 and has a short spacerproximal end 168 and a short spacerdistal end 170. In the illustrated embodiment, the short spacerproximal end 168 is even or substantially even withfront edge 105 and short spacerdistal end 170 is disposed betweenfront edge 105 andrear edge 107. Likestandoffs 117, in the illustrated embodimentshort spacers 123 each have a short spacer height that is the same or substantially the same as the first sidewall height and the second sidewall height at a corresponding portion of thefirst sidewall 113 andsecond sidewall 115. That is, the height measured at any point between a lower surface ofshort spacer 123 and a point of intersection betweenshort spacer 123 andbottom side 103 may be the same or substantially the same as the first sidewall height or second sidewall height measured at a corresponding point onfirst sidewall 113 andsecond sidewall 115. - In the illustrated embodiment
short spacers 123 have a thickness and two sides, wherein the two sides have a trapezoidal shape. Such a configuration is not required, however, andshort spacers 123 may have any suitable geometric or irregular shape. For example, the sides of short spacers may have triangular, quadrilateral (square, rectangular, trapezoidal, etc.), pentagonal, or other shape. Without limitation, the shape of the sides ofshort spacers 123 is the same or substantially the same as the shape of a corresponding point offirst sidewall 113 andsecond sidewall 115. In embodiments and as best shown inFIG. 1S , at least a portion of short spacerdistal end 170 is in contact with areinforcement 121. - Among other things,
short spacers 123 function to supportbottom side 103 and to maintain a gap G2 betweenbottom side 103 and material underlying roofing panel 100 (e.g., shingles, a biocidal source, etc.). More specifically, whenroofing panel 100 is installed, a lower side ofshort spacers 123 may contact material underroofing panel 100, and limit or preventbottom side 103 from sagging, bowing, or the like. While the illustrated embodiments depictshort spacers 123 with a short spacerproximal end 168 that is even withfront edge 105, such a configuration is not required. In embodiments short spacerproximal end 168 extends pastfront edge 105, e.g., by an offset distance O1 and/or O2 as discussed above. In such embodiments, aroofing retention element 141 may be integral with or coupled to part ofshort spacer 123 that extends pastfront edge 105. - The roofing panels described herein may include features that allow it to couple or otherwise connect with additional roofing panels, so as to increase the area of a biocidal source and/or roof that may be covered. For example, one side of
roofing panel 100 may include one or more female coupling elements and the other side of roofing panel may include one or more male coupling elements. In such instances, the female coupling element(s) of a first roofing panel may couple with male coupling elements of a second roofing panel. Likewise, the male coupling element(s) of the first panel may couple with the female coupling element(s) of a third roofing panel. The female and male coupling elements may be configured such that when a first panel is coupled to a second panel, thetop side 101 of the first panel is coplanar or substantially coplanar with the top side of the second panel. - With the foregoing in mind,
FIGS. 1A-1Z depict an embodiment in whichroofing panel 100 includes first and secondfemale coupling elements male coupling elements FIG. 1U , first and secondfemale coupling elements first sidewall 113 ofroofing panel 100. In the illustrated embodiments, firstfemale coupling element 125 is in the form of a receptacle formed at an intersection betweentop side 101 andfirst sidewall 113. The receptacle includes anopening 127, which is sized and configured to receive a corresponding male coupling element, such as firstmale coupling element 131 of another roofing panel. Secondfemale coupling element 129 is in the form of one or more slots formed infirst sidewall 113, wherein the slots extend through the thickness offirst sidewall 113, and extend fromlower side 163 towards an upper part offirst sidewall 113. In the illustrated embodiment, the slots of the secondfemale coupling element 129 are each sized and configured to receive part of a second male coupling element, e.g., a corresponding interface member of another roofing panel. - As best shown in
FIG. 1Z first and secondmale coupling elements second sidewall 115 ofroofing panel 100. In the illustrated embodiments, firstmale coupling element 131 is in the form of a protuberance that extends fromsecond sidewall 115 at a point proximateright edge 111. The protuberance is sized and configured such that it is receivable in a female coupling element, e.g., anopening 127 in a female coupling element of another roofing panel. Secondmale coupling element 133 is configured to be received within a second female coupling element of another roofing panel, such as one or more slots of a secondfemale coupling element 129. In the illustrated embodiment, secondmale coupling element 133 includes a plurality ofinterface members 137 that extend fromsecond sidewall 115 oroptional indentations 147 insecond sidewall 115. The secondmale coupling element 133 further includes across member 135 that extends between and couples the plurality ofinterface members 137. Anopening 139 is present between two sequential interface members and betweencross member 135 andsecond sidewall 115. - In operation, first and second roofing panels configured in the manner shown in
FIGS. 1A-1Z may be coupled together by inserting the protuberance of firstmale coupling element 131 into theopening 127 of firstfemale coupling element 125 and by disposinginterface members 137 through the slots of secondfemale coupling element 129, such that part ofsidewall 113 is disposed through theopenings 139 andcross member 135 is proximate an inward acing side offirst sidewall 113. - Of course, the roofing panels described are not limited to using coupling elements that are configured in the manner shown in
FIGS. 1A-1Z . Indeed, the present disclosure encompasses embodiments in which the roofing panels described herein can be coupled to another roofing panel in any suitable manner. For example, roofing panels described herein may be configured to couple to another roofing panel via one or more mechanical fasteners, an adhesive, a tape, mechanical interference fit joint, a snap fit joint, combinations thereof, and the like. - The roofing panels described herein may be coupled to a surface such as a roof in any suitable manner, such as via an adhesive, a mechanical fastener (e.g., nails, screws, etc.), combinations thereof, and the like. In that regard,
FIGS. 1A-1Z depict an embodiment of a roofing panel that includesfirst fastener openings 143 andsecond fastener openings 145. The first and second fastener openings are generally configured to receive a mechanical or chemical fastener therein and to facilitate retention ofroofing panel 100 to a surface (e.g., roof) and/or to roofing material (e.g., a shingle) by such fastener(s). The first andsecond fastener openings - In embodiments,
first fastener opening 143 is smaller thansecond fastener opening 145. In such instancesfirst fastener opening 143 may be provided to provide enhanced contact between an adhesive used to adhere roofing material (e.g., a shingle) totop side 101 ofroofing panel 100. Thetop side 101 may further includeoptional grooves 149, which may also function to provide enhanced contact with an adhesive used to adhere roofing material totop side 101. In contrast, second fastener opening 145 may be configured to receive a mechanical fastener there through, wherein the mechanical fastener is to couple theroofing panel 100 to an underlying surface, such as a roof. - In embodiments, a gasket or other seal (not shown) is provided around or within first and second fastener openings, and functions to limit or prevent leakage of water there through. In embodiments, the gasket or seal is in the form of a rubber gasket (e.g., a solid disc or O-ring formed of butyl rubber or other suitable elastomeric material)
-
Roofing panel 100 is preferably sufficiently flexible as to allow it to be rolled upon itself, e.g., fromfirst sidewall 113 tosecond sidewall 115 or vice versa. In that regard, all or a portion of the body member may be formed from one or more flexible polymeric materials, such as but not limited to elastomeric polymers, rubbers, combinations thereof, and the like. Non-limiting examples of such materials include flexible polymers, e.g., polyolefins such as polyethylene (e.g., high density polyethylene), polypropylene, combinations thereof and the like. Without limitation, inembodiments roofing panel 100 is configured such that it can be rolled upon itself with a coil length that is less than one half (preferably less than one quarter or even one eighth) of the distance betweenfirst sidewall 113 tosecond sidewall 115. In those or other embodiments,roofing panel 100 is configured to be rollable even when coupled to additional roofing panels, e.g., via the male and female coupling elements discussed above. Thus, for example, a plurality ofroofing panels 100 may be coupled to one another via coupling elements to form an elongated chain of roofing panels that can be rolled into a single continuous roll. -

The body of anupstream shingle 209 is also installed onfirst shingle 203. Aroofing panel 100 is installed over thebiocidal source 201 and below the lower end of the body ofupstream shingle 209, e.g., with one or more mechanical fasteners driven throughsecond fastener openings 145. Before or after the installation ofroofing panel 100, aprofile portion 211 may be separated fromupstream shingle 209 or another shingle. Theprofile portion 211 may be adhered to thetop side 101 ofroofing panel 100 via an adhesive, a mechanical fastener, or both. To facilitate retention of theprofile portion 211 on top side 101 (particularly when an adhesive is used), the lower edge ofprofile portion 211 may be supported by the abutment surface ofroofing retention elements 141, as shown. First andsecond sidewalls standoffs 117 provide a gap betweenupstream shingle 209 androofing panel 100. In operation,water 250 flowing down the roof will flow through channels betweenstandoffs 117 and onto the exposed surface ofbiocidal source 201 that is covered by the body ofroofing panel 100. Thewater 250 will continue to flow downhill and through the gap provided by first andsecond sidewalls biocidal source 201 and thebottom side 103 ofroofing panel 100. Biocidal material incorporated into thewater 250 will then be distributed over the other parts of theroof 207 as the water flows downstream of theroofing panel 100. - Example 1: According to this example there is provided a roofing panel, including: a body having a top side, a bottom side parallel with the top side, a front edge, a rear edge, a right edge, and a left edge; a first sidewall extending from the bottom side, the first sidewall including a first sidewall distal end proximate the rear edge and a first sidewall proximal end proximate the front edge; a second sidewall extending from the bottom side, the second sidewall including a second sidewall distal end proximate the rear edge and a second sidewall proximal end proximate the front edge; wherein: the first and second sidewalls each have a sidewall height that tapers from a height HR proximate the rear edge and a height HF proximate the front edge; HF is less than HR; and HF is greater than 0.
