FASTENER PLATE FOR SECURING AN UNDERLAYMENT TO A ROOF SURFACE

FIELD OF THE DISCLOSURE

The present disclosure relates generally to roofing systems, and more particularly to improved fastener plates for securing an underlayment to a roof surface, the structure of the fastener plate enabling a subsequently applied liquid coating to flow therein to provide a complete seal.

BACKGROUND OF THE DISCLOSURE

It is generally known in the art to apply a liquid coating such as, for example, a silicone coating or the like, to a roof surface for moisture protection. In some applications, such as, for example, mechanically fastened liquid-applied roofing systems, an underlayment such as, for example, a polypropylene or synthetic underlayment, may be initially secured to the roof surface via, for example, fasteners such as, for example, screws, nails, etc. In addition, a fastener plate may be used to better secure the underlayment to the roof surface. In use, fasteners extend through an opening formed in such fastener plates, through the underlayment and into the roof surface.

Installation of fasteners into the roof surface however create pathways, voids, spaces, etc. for moisture to enter the roof surface. As such, these pathways, voids, spaces, etc. (used interchangeably herein without the intent to limit) should be properly sealed by the liquid coating to prevent the introduction of moisture into the roof surface.

Currently, fastener plates suffer in that they are not properly designed to ensure that enough liquid coating can seal the area around the fastener and the pathway created by the introduction of the fastener. That is, one disadvantage with known fastener plates is that they do not provide structures that enable a sufficient amount of coating to properly seal the spaces created by the introduction of the fasteners used to secure the underlayment to the roof surface. For example, when using a silicone based liquid coating, fastener plates are generally omitted because they are not designed to permit the silicone based liquid coating to seal the area around the fastener and the pathway created by the introduction of the fastener.

It would be desirable to provide an improved fastener plate for coupling an underlayment to a roof surface. In particular, it would be beneficial to design a fastener plate that can be used with silicone-based liquid coatings.

DETAILED DESCRIPTION

Numerous embodiments of an improved fastener plate in accordance with the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the present disclosure are presented. The fastener plate of the present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will convey certain aspects of the fastener plate to those skilled in the art. In the drawings, like numbers refer to like elements throughout unless otherwise noted.

As will be described in greater detail below, in accordance with one aspect of the present disclosure, an improved fastener plate for use in coupling an underlayment to a roof surface is disclosed. In one embodiment, the fastener plate includes features arranged and configured to create openings and cavities to facilitate flow of subsequently applied liquid coating to ensure the area around the fastener and the pathway created by the introduction of the fastener is properly sealed to prevent, or at least inhibit, the introduction of moisture into the roof surface.

Generally speaking, as will be appreciated by one of ordinary skill in the art, in use, an underlayment may be installed onto a roof surface, deck, substrate, etc. (used interchangeably herein without the intent to limit). One commercially available underlayment includes Tiger Paw™ UV-stabilized polypropylene underlayment provided by GAF® Materials Corporation. Alternatively, another commercially available underlayment includes Adfors W4520 or W4503 roofing reinforcement.

In use, the underlayment may be coupled to the underlying roof surface by any mechanism now known or hereafter developed including, for example, mechanical fasteners (nails, staples, screws, etc.).

Thereafter, a liquid coating may be applied onto the underlayment. The liquid coating can be any liquid coating now known or hereafter developed including, for example, a coating comprising silicone, an acrylic, a polyurethane, an epoxy, a poly(methyl methacrylate) (PMMA), STP, or the like. For example, in one embodiment, one commercially available coating includes Unisil HS silicone roof coating provided by GAF® Materials Corporation. In use, the liquid coating can be applied to a top surface of the underlayment by any mechanism now known or hereafter developed including, for example, spraying, rolling, brushing, etc.

In order to properly protect the roof surface from moisture damage via the introduction of unwanted moisture, any voids, spaces, or pathways (used interchangeably herein without the intent to limit) should be properly sealed by the liquid applied coating. That is, the liquid applied coating should seal and protect the roof surface from the introduction of moisture through any unwanted voids including, for example, any pathways created by the introduction of the fasteners for securing the underlayment to the roof surface.

Referring to FIGS. 1A-1D, one embodiment of an improved fastener plate 100 is disclosed. In use, the fastener plate 100 can be used to couple an underlayment 60 (FIG. 1D) to a roof surface 70 (FIG. 1D). As will be described in greater detail, in one embodiment, the fastener plate 100 is arranged and configured with one or more features to enable subsequently applied liquid coating 80 (FIG. 1D) to pass through the fastener plate 100 to seal against the fastener 50 (FIG. 1D) used to couple the underlayment 60 the roof surface 70.

As illustrated, the fastener plate 100 includes a top surface or portion 102 (used interchangeably herein without the intent to limit), a bottom surface (e.g., an underlayment contacting surface) 104, and an outer edge surface or perimeter 106. In use, the top surface 102 is spaced apart from the bottom surface 104 so that one or more cavities 140, as will be described in greater detail below, are formed between the top surface 102 and the bottom surface 104 of the fastener plate 100. The bottom surface 104 may be an open-ended bottom surface (e.g., including one or more projections for contacting the underlayment) (schematically shown in FIGS. 1A-1D) or may be in the form of a closed-ended bottom surface with one or more openings formed therein (schematically shown in FIGS. 2A-2C). Thus arranged, referring to FIG. 2C, in one embodiment, the fastener plate 100 may include a plurality of spacers 180 on the bottom surface 104 thereof. In use, the spacers 180 contact the top surface of the underlayment 60. In use, the spacers 180, may define the bottom surface 104 of the plate 100. As such, the spacers 180 prevent, or at least minimize, the fastener plate 100 from damaging (e.g., cutting) the underlying fabrics such as, for example, the underlayment 60, waterproof layer, etc. In use, the spacers 180 can be arranged and configured in any manner so long as they prevent, or at least minimize, the fastener plate 100 from damaging (e.g., cutting) the underlying fabrics (e.g., eliminate, reduce, etc. any sharp components from cutting into the underlying fabrics such as, the underlayment 60). For example, the spacers 180 may be an attachment component such as, for example a glued piece, or the like. Alternatively, the spacers 180 may be or form part of the bottom surface 104 of the fastener plate 100 such as, for example, a stamped foot or the like.

In addition, the fastener plate 100 includes one or more fastener openings 108 in the top surface 102 thereof for receiving one or more fasteners 50 for securing the fastener plate 100 to the underlayment 60 and roof surface 70. Thus arranged, in use, the fastener 50 and the fastener plate 100 couple, secure, attach, etc. (used interchangeably herein without the intent to limit) the underlayment 60 to the roof surface 70.

As illustrated, the fastener plate 100 may include a circular shape, however, as will be described and illustrated in greater detail below, the fastener plate 100 may have any shape including, for example, oval, square, rectangular, etc. In one embodiment, the fastener plate 100 may include a dome shape (e.g., height in center adjacent to the fastener opening 108 is greater than the height at the outer edge or perimeter 106) so that, as will be described in greater detail, the center area (e.g., area where the fastener 50 passes through) is surrounded with a thicker layer of subsequently applied liquid coating 80.

As illustrated, the fastener plate 100 also includes a plurality of openings 120 extending through the top surface 102 thereof. In use, the openings 120 are sized and configured to enable subsequently applied coating 80 to pass through the fastener plate 100 and into contact with, for example, the fastener 50 and the underlayment 60. That is, in one embodiment, the openings 120 are arranged and configured to enable liquid coatings 80 including, for example, silicone-based liquid coatings, to flow sufficiently through the top surface 102 of the fastener plate 100. As illustrated in FIGS. 1A-1D, the openings 120 may be circular openings. However, the openings 120 may have any size and shape, and may be provided in any numbers and may be are arranged and configured in any manner to enable subsequently applied coating 80 to pass through the top surface 102 of the fastener plate 100 and into cavities 140 formed underneath. For example, the fastener plate 100 may include between 3 and 18 openings 120, although more or less openings are envisioned. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 10% to 90% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 20% to 90% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 30% to 90% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 50% to 90% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 70% to 90% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 10% to 80% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 10% to 50% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 10% to 40% of the total surface area of the fastener plate. In one embodiment, it is envisioned that the total cumulative size of the openings will be between 10% to 30% of the total surface area of the fastener plate. In one embodiment, the total cumulative size of the openings will be between 25% and 75% of the total surface area of the fastener plate, although more or less is envisioned.

In addition, the fastener plate 100 may include a plurality of projections 130 extending from the top surface 102 thereof. In use, the projections 130 form one or more cavities 140 between the top surface 102 of the fastener plate 100 and the underlayment 60 for receiving subsequently applied liquid coating 80. In use, the cavities 140 formed by the projections 130 are arranged and configured to maintain a desired thickness of subsequently applied coating 80 (e.g., height of cavities 140 should be sufficient to enable the subsequently applied liquid coating 80 to flow therein). In one embodiment, it is envisioned that the height to diameter ratio of the fastener plate 100 will be approximately 0.5. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.25. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.3. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.4. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.6. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.8. In an alternate embodiment, the height to diameter ratio of the fastener plate 100 may be approximately 0.9. As such, a four-inch plate may have a one-inch height, although other dimensions/ratios are envisioned.

In one embodiment, as schematically shown in FIG. 3B, the projections 130 may include a bottom edge 132 adapted and configured to contact the underlayment 60. For example, the bottom edge 132 of the projections 130 may include a rounded or spherical end portion to enable the projections 130, and hence the fastener plate 100, to contact the underlayment 60 without cutting into or piercing the underlayment 60 during, for example, tightening of the fastener 50. In use, the projections 130 may also be arranged and configured to prevent compressing of the fastener plate 100 and thus closing of the cavities 140 formed therein during, for example, tightening of the fastener 50.

Referring to FIGS. 1A-1D, when used with a circularly-shaped fastener plate, the projections 130 may be circumferentially disposed about an area of the plate 100. In addition, the fastener plate 100 may include two sets of circumferentially disposed projections 130 (e.g., inner and outer sets or groups of circumferentially disposed projections 134, 136), although it is envisioned that the fastener plate 100 may include more or less sets of projections 130 including, one, three, four, or more. In use, as illustrated, the individual projections 130 in each set of projections 134, 136 are discontinuous so that adjacent projections 130 are separated from each other by gaps 135, 137. In addition, as illustrated, in one embodiment, the projections 130 and gaps 135 of a first set of projections 134 may be offset or misaligned relative to the projections 130 and gaps 137 of a second set of projections 136. In this manner, a longer, more curvaceous pathway is created to better protect against the introduction of moisture from the outer edge surface or perimeter 106.

As shown, for example, in FIGS. 1A-1D, 2B, 2C, 3A, 3B, and 4B, the fastener opening 108 may be countersunk so that, in use, an area above a head 52 of the fastener 50 may be sealed (e.g., covered) by subsequently applied liquid coating 80. In addition, the fastener opening 108 may be arranged and configured so that an area surrounding the head 52 of the fastener 50 is also sealed (e.g., covered) by subsequently applied liquid coating 80. In this manner, the entire area surrounding the fastener 50 may be sealed by subsequently applied liquid coating 80. In one embodiment, the head 52 of the fastener 50 may be sunken by up to half or more of the height of the opening 108 to allow effective filling of both the head 52 of the fastener 50 and the body of the fastener 50. In addition, it should be understood that while a single fastener opening is disclosed and illustrated, the fastener plate may include multiple fastener openings. Additionally, the fastener openings may be located anywhere in the fastener plate.

By incorporating a plurality of openings 120 and a plurality of projections 130 forming a plurality of cavities 140, the fastener plate 100 is arranged and configured to enable subsequently applied liquid coating 80 to pass through the top surface 102 of the fastener plate 100 and into the cavities 140 defined by the projections 130. In addition, by incorporating a countersunk fastener opening 108, the fastener plate 100 is arranged and configured to enable subsequently applied liquid coating 80 to cover and seal against the head 52 of the fastener 50. Thus arranged, the fastener plate 100 ensures efficient filling of the cavities 140 with the coating 80 and efficient filling of the pathway formed by the introduction of the fastener 50 into the underlayment 60 and the roof surface 70, thus ensuring proper sealing of the roof surface 70 from the introduction of moisture through the space created by the introduction of the fasteners 50.

As previously mentioned, the fastener plate 100 may include any shape. For example, referring to FIGS. 4A and 4B, in one embodiment, the fastener plate 100 may include a rectangular shape. In one embodiment, when manufactured with a rectangular shape, the fastener plate 100 may include open side edges 111 (e.g., sides are completely open) to enable subsequently applied liquid coating 80 to flow there through. Thus arranged, in use, the rectangular shaped fastener block may be installed with the open side edges extending perpendicular to the direction of incoming wind to minimize edge cutting to the underneath structures caused by the wind lifting the plate.

Referring to FIGS. 5A-5C, in one embodiment, the fastener plate 100 may also include a thin layer of material 150 such as, for example, a mesh material. In use, the layer of material 150 may be secured to the fastener plate 100 such as, for example, via an adhesive. The layer of material 150 may be coupled underneath the fastener plate (FIGS. 5A and 5B), on top of the fastener plate 100 (FIG. 5C), or both. The layer of material 150 may encompass the entire area below the top surface 102 of the fastener plate 100 (FIG. 5B), or only some thereof (FIG. 5A). In use, the layer of material 150 provides a buffer padding thus eliminating, or at least minimizing, the potential of any sharp edges of the fastener plate 100 damaging, for example, the underlayment 60 or the top coating.

Referring to FIGS. 6A-6D, an example embodiment of an improved fastener plate 100 is disclosed. As will be shown and described, the fastener plate 100 is substantially similar to the fastener plates previously described. As previously described, in use, the fastener plate 100 can be used to couple an underlayment 60 (FIG. 1D) to a roof surface 70 (FIG. 1D). The fastener plate 100 may be arranged and configured with one or more features to enable subsequently applied liquid coating 80 (FIG. 1D) to pass through the fastener plate 100 to seal against the fastener 50 (FIG. 1D) used to couple the fastener plate 100 to the underlayment 60 and the roof surface 70.

As illustrated, the fastener plate 100 includes a top surface 102, a bottom surface (e.g., an underlayment contacting surface) 104, and an outer edge surface or perimeter 106. In use, the top surface 102 is spaced apart from the bottom surface 104 so that one or more cavities 140 are formed. As illustrated, the bottom surface 104 generally defines an open-ended bottom surface.

As shown, and as previously mentioned, the fastener plate 100 may include one or more fastener openings 108 in the top surface 102 thereof for receiving one or more fasteners 50, respectively, for securing the fastener plate 100 to the underlayment 60 and roof surface 70. As illustrated, the fastener opening 108 may be centrally positioned, although other configurations are envisioned (e.g., while a single fastener opening is disclosed and illustrated, the fastener plate may include multiple fastener openings. Additionally, the fastener openings may be located anywhere in the fastener plate). In use, the fastener opening 108 is arranged and configured to receive a fastener 50 to couple the fastener plate 100 to the underlayment 60 and roof surface 70. As shown, the fastener opening 108 may be countersunk so that, in use, an area above a head 52 of the fastener 50 may be sealed (e.g., covered) by subsequently applied liquid coating 80. In addition, the fastener opening 108 may be arranged and configured so that an area surrounding the head 52 of the fastener 50 is also sealed (e.g., covered) by subsequently applied liquid coating 80. In this manner, the entire area surrounding the fastener 50 may be sealed by subsequently applied liquid coating 80.

As illustrated, the fastener plate 100 includes a circular, domed shape, however, as previously mentioned, the fastener plate 100 may have any shape. By providing a dome shape, the fastener plate 100 includes a height in a center area adjacent to the fastener opening 108 that is greater than the height of the fastener plate 100 at the outer edge or perimeter 106 so that the center area (e.g., area where the fastener 50 passes through) is surrounded with a thicker layer of subsequently applied liquid coating 80.

In addition, as illustrated, the fastener plate 100 also includes a plurality of openings 120 extending through the top surface 102 thereof. In use, the openings 120 are sized and configured to enable subsequently applied coating 80 to pass through the fastener plate 100 and into contact with, for example, the fastener 50 and the underlayment 60. That is, the openings 120 may be arranged and configured to enable liquid coating 80 including, for example, silicone-based liquid coating, to flow sufficiently through the top surface 102 of the fastener plate 100 and into the cavity 140 formed therein. As illustrated, the openings 120 may be circular openings. However, the openings 120 may have any size and shape, and may be provided in any numbers and may be are arranged and configured in any manner to enable subsequently applied coating 80 to pass through the top surface 102 of the fastener plate 100 and into the cavity 140 formed underneath.

In addition, the fastener plate 100 may include a plurality of projections 130 extending from the top surface 102 thereof. In use, the projections 130 are arranged and configured to contact the underlayment 60 while preventing, or at least minimizing, compression of the fastener plate 100 (e.g., compressing of the top surface 102 towards the bottom surface 104) and thus closing or reducing of the cavity 140 formed therein during, for example, tightening of the fastener 50. Thus arranged, the projections 130 facilitate maintaining a desired height so that subsequently applied liquid coating 80 can flow into the cavity 140. In one embodiment, the projections 130 include a bottom edge adapted and configured to contact the underlayment 60 without cutting into or piercing the underlayment 60 during, for example, tightening of the fastener 50. As illustrated, when used with a circularly-shaped fastener plate, the projections 130 may be circumferentially disposed about an area of the plate 100.

By incorporating a plurality of openings 120, a plurality of projections 130, and one or more cavities 140, the fastener plate 100 is arranged and configured to enable subsequently applied liquid coating 80 to pass through the top surface 102 of the fastener plate 100 and into the cavity 140, where it may seal against the fastener 50 and the underlayment 60 thereby preventing, or at least minimizing, openings that enable the entry of moisture. In addition, by incorporating a countersunk fastener opening 108, the fastener plate 100 is arranged and configured to enable subsequently applied liquid coating 80 to cover and seal against the head 52 of the fastener 50. Thus arranged, the fastener plate 100 ensures efficient filling of the cavity 140 with the coating 80 and efficient filling of the pathway formed by the introduction of the fastener 50 into the underlayment 60 and the roof surface 70, thus ensuring proper sealing of the roof surface 70 from the introduction of moisture through the space created by the introduction of the fasteners 50.

Referring to FIGS. 7A and 7B, an alternate, example embodiment of an improved fastener plate 100 is disclosed. The fastener plate 100 shown and described in connection with FIGS. 7A and 7B is substantially similar to the fastener plate shown and described in connection with FIGS. 6A-6D, thus, for the sake of brevity, only the differences are described herein.

As illustrated, the fastener plate 100 includes a stiffened or reinforced region 200 positioned about the centrally positioned, fastener opening 108. The stiffened region 200 is arranged and configured to prevent, or at least minimize, compressing of the fastener plate 100 and thus closing or reducing of the cavity 140 (e.g., prevents the top surface 102 adjacent to the center area from compressing towards the bottom surface 104). In use, the stiffened region 200 may take the place of, or be used in combination with, one or more projections 130 extending from the top surface 102 as previously described.

In use, the stiffened region 200 may have any structure and/or configuration arranged and configured to prevent, or at least minimize, compressing of the fastener plate 100 during tightening of the fastener 50. As illustrated, for example, the stiffened region 200 may include a plurality of projections 205 positioned circumferentially about the fastener opening 108. In use, the plurality of projections 205 are sufficiently rigid to prevent, or at least minimize, the top surface 102 from compressing due to tightening of a fastener 50 within the fastener opening 108.

Referring to FIGS. 8A-8C, an alternate, example embodiment of an improved fastener plate 100 is disclosed. The fastener plate 100 shown and described in connection with FIGS. 8A-8C is substantially similar to the fastener plate shown and described in connection with FIGS. 7A and 7B, thus, for the sake of brevity, only the differences are described herein.

As illustrated, and as previously described, the fastener plate 100 includes a plurality of openings 120 extending through the top surface 102 thereof. In accordance with the present embodiment however, at least one or some of the plurality of openings 120A are positioned along the outer perimeter 106 of the fastener plate 100. By providing one or more openings 120A along, or in communication with, the outer perimeter 106 of the fastener plate 100, it has been discovered that increased fluid flow is obtained.

Referring to FIGS. 9A-9C, an alternate, example embodiment of an improved fastener plate 100 is disclosed. The fastener plate 100 shown and described in connection with FIGS. 9A-9C is substantially similar to the fastener plate shown and described in connection with FIGS. 7A-7B, thus, for the sake of brevity, only the differences are described herein.

As illustrated, in connection with the embodiment of FIGS. 9A-9C, the fastener plate 100 includes a stiffened region 200 positioned about the fastener opening 108. The stiffened region 200 including a plurality of projections 205 positioned circumferentially about the fastener opening 108. In use, the plurality of projections 205 are sufficiently rigid to prevent, or at least minimize, the top surface 102 from compressing due to tightening of a fastener 50 within the fastener opening 108. However, in connection with the present embodiment, the plurality of projections 205 extend below the bottom surface 104 of the fastener plate 100. Thus arranged, the plurality of projections 205 (e.g., center ring) is arranged and configured as a load bearing point. As such, the stiffened region 200 is adapted and configured to minimize torque on the fastener plate 100 during tightening.

The fastener plate 100 may be manufactured from any material now known or hereafter developed including, for example, metal, plastic, polymer, etc. In one embodiment, the fastener plate 100 may contain a certain amount of flexibility to enable the fastener plate 100 to flex and to prevent, or at least inhibit, sharp edges. Referring to FIG. 2C, in connection with a fastener plate 100 manufactured from metal, in one embodiment, the outer edge surface 106 may include an inwardly projecting lip 107 to prevent, or at least inhibit, the fastener plate 100 from cutting into the underlayment 60. Referring to FIGS. 3A and 3B in connection with a fastener plate 100 manufactured from plastic, in one embodiment, the outer edge surface 106 may include a rounded, spherical, flexible, etc. edge portion to prevent, or at least inhibit, the fastener plate 100 from cutting into the underlayment 60. As will be readily appreciated by one of ordinary skill in the art, the plastic fastener plate may include an inwardly projecting lip and the metal fastener plate may include a rounded edge portion. Moreover, other configurations are envisioned including, for example, straight edge portion.

The fastener plates 100 may be manufactured in any appropriate size. For example, in connection with circular designed fastener plates 100, the fastener plates 100 may include a diameter of 1 to 10 inches. In one embodiment, the fastener plates 100 may have a diameter of 2 to 4 inches. In one embodiment, the fastener plates 100 may have a diameter of 2 to 8 inches. In one embodiment, the fastener plates 100 may have a diameter of 2 to 6 inches. In one embodiment, the fastener plates 100 may have a diameter of 1 to 8 inches. In one embodiment, the fastener plates 100 may have a diameter of 1 to 6 inches.

In use, by incorporating a fastener plate 100 in accordance with one or more of the principles of the present disclosure, fastener plates 100 can be used to secure the underlayment 60 to the roof surface 70 even with, for example, silicone-based liquid applied coatings 80. That is, currently, when using a silicone-based liquid coating 80, fastener plates 100 are omitted because they do not enable enough silicone coating 80 to pass through the fastener plate to seal the opening created by introduction of the fastener 50. In contrast, in accordance with the principles of the fastener plates 100 disclosed herein, the fastener plates 100 enable sufficient flow through so that fastener plates 100 can be used even with, for example, silicone-based liquid coatings 80.

In use, in one embodiment, the underlayment 60 can be secured to the roof surface 70 using a plurality of fasteners 50 passing through a plurality of fastener plates 100, respectively. Thereafter, the liquid applied coating 80 can be installed over the underlayment 60 including over the fastener plates 100 and fasteners 50. The coating 80 flowing through the openings 120 formed in the fastener plates 100 and into the cavities 140 defined therein. In addition, the coating 80 flows into the fastener opening 108 and over and around the head 52 of the fastener 50. Thus arranged, the fastener 50 and the opening created by the introduction of the fastener 50 is sealed by the subsequently applied liquid coating 80. For best results, in use, the entire footprint of the fastener plates 100 may be covered by the subsequently applied liquid coating 80.

While the present disclosure refers to certain embodiments, numerous modifications, alterations, and changes to the described embodiments are possible without departing from the sphere and scope of the present disclosure, as defined in the appended claim(s). Accordingly, it is intended that the present disclosure not be limited to the described embodiments, but that it has the full scope defined by the language of the following claims, and equivalents thereof. The discussion of any embodiment is meant only to be explanatory and is not intended to suggest that the scope of the disclosure, including the claims, is limited to these embodiments. In other words, while illustrative embodiments of the disclosure have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed, and that the appended claims are intended to be construed to include such variations, except as limited by the prior art.

The foregoing discussion has been presented for purposes of illustration and description and is not intended to limit the disclosure to the form or forms disclosed herein. For example, various features of the disclosure are grouped together in one or more aspects, embodiments, or configurations for the purpose of streamlining the disclosure. However, it should be understood that various features of the certain aspects, embodiments, or configurations of the disclosure may be combined in alternate aspects, embodiments, or configurations. Moreover, the following claims are hereby incorporated into this Detailed Description by this reference, with each claim standing on its own as a separate embodiment of the present disclosure.

As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.

The phrases “at least one”, “one or more”, and “and/or”, as used herein, are open-ended expressions that are both conjunctive and disjunctive in operation. The terms “a” (or “an”), “one or more” and “at least one” can be used interchangeably herein. All directional references (e.g., proximal, distal, upper, lower, upward, downward, left, right, lateral, longitudinal, front, back, top, bottom, above, below, vertical, horizontal, radial, axial, clockwise, and counterclockwise) are only used for identification purposes to aid the reader's understanding of the present disclosure, and do not create limitations, particularly as to the position, orientation, or use of this disclosure.
