Abstract
A roof seam fastener system including a mechanical fastener member for mechanically attaching a roof membrane to a roof structure. The roof seam fastener system comprises a fastening assembly that creates a seal to either the roof membrane or a roofing substrate located directly below the fastening assembly. This fastening assembly also creates a seal against the mechanical fastener member. This combination results in redundancy which prevents any water penetration into the seam from entering the roofing envelope. The roof seam fastener system improves wind uplift resistance of the roof membrane and minimizes other weather related damage.
Description
- 1. Field of the Invention
- The invention relates in general to a mechanical attachment system for securing roof membranes, and more particularly, to a mechanical attachment system for securing roof membranes wherein a seal is achieved between the mechanical attachment device and the roof membrane and/or material directly below it, minimizing weather related damage.
- 2. Description of Related Art
- Single-ply roofing systems are typically installed using three basic methods: ballasted, fully adhered, and mechanically attached. Mechanically attached single-ply roof membranes are attached to a structure using various types of metal and plastic fasteners which are installed through strips or plates made from metal, plastic or a combination of the two.
- One typical installation method is illustrated in
FIG. 1 . In this method, aroof membrane substrate 2 is positioned adjacent to aroof decking 4. A first sheet ofroofing membrane 6 having afirst edge 8 is laid onto theroof membrane substrate 2. A fastener assembly, generally illustrated as 10, is installed along thisfirst edge 8 of the first sheet ofroofing membrane 6 to secure theroofing membrane 6 to theroof membrane substrate 2. Thefastener assembly 10 comprises aclamping device 12, which is positioned on top of thefirst edge 8 of thefirst roofing membrane 6, and afastener 14, such as a nail, screw or the like. Thefastener 14 extends through theclamping device 12,first roofing membrane 6, androof membrane substrate 2 and then into theroof decking 4. An adjacent or second sheet ofroofing membrane 16, having asecond edge 18, is then applied such that thissecond edge 18 overlaps thefirst edge 8 of thefirst membrane 6 and thefastener assembly 10. Aportion 9 of thefirst edge 8 andsecond edge 18 of the overlapping first andsecond membranes second roofing membrane 16 and theroof membrane substrate 2. - Although this method of attaching a roofing membrane is commonly used, there are several drawbacks to this attachment method. As shown in
FIG. 2 , this particular method is susceptible to failure caused byuplift forces 11 during wind loads or constant positive pressure loads due to asymmetrical loading, as shown byarrow 13, of thefastener assembly 10. The asymmetrical loads cause crushing of theroof membrane substrate 2, due to thefastener 14 rocking under the load, immediately below theroof membranes fastener assembly 10 against theroof membrane substrate 2 is lessened. This compression is necessary to prevent theroof membranes fastener 14. Another disadvantage of this system is that theseam 20 also experiences a significant amount of peeling force, as shown byarrows - In an attempt to overcome the difficulties of this roof membrane attachment method shown in
FIGS. 1 and 2 , manufacturers have begun to create an additional orsecond seam 22, for joining aportion 24 of thesecond roofing membrane 16 to aportion 25 of thefirst roofing membrane 6, as shown inFIG. 3 , on the opposite side of thefastener assembly 10. Accordingly, theroof membranes fastener assembly 10 so that anyuplift forces 11 caused by wind, as shown inFIG. 4 , are applied symmetrically, as shown byarrows fastener assembly 10. This symmetrical application of force prevents crushing of themembrane substrate 2 and eliminates peel forces which can be exerted on theseams seams - As illustrated in
FIG. 5 , in an effort to reduce labor costs, rolls of theroofing membrane membranes fastening tab 30. These panels ofroofing membrane 28 are laid onto theroof membrane substrate 2. A portion of theroofing membrane 16 is lifted upward so that thefastener assembly 10 can be installed through thefastening tab 30. Although this method offers labor saving during the installation, it is still subject to the asymmetrical loading and peel force described above and illustrated inFIG. 2 . In order to overcome the problems of asymmetrical loading and peel force, this method can include a second seaming operation performed on site after the application of thefastening assembly 10, as described above with respect toFIG. 3 and shown again inFIG. 6 . - As an alternative to the seam overlap attaching methods discussed above, another method for attaching a roofing membrane to a roof membrane substrate is shown in
FIG. 7 . This method includes the use of asupplemental member 32 formed of a compatible material located beneath aroof membrane 34 which are attached to theroof membrane substrate 2. Thefastener assembly 10 secures this supplemental member to theroof membrane substrate 2. Thesupplemental member 32 can have a circular shape or any other shape. Theroof membranes 34 are overlapped sufficiently to allow a seam and then attached on their underside viaseams supplemental member 32 by using one of the seaming methods described above. One advantage of this method is the ability to locate fastener assemblies independent of the roof membrane overlaps. This can be particularly advantageous when the rolls of roof membrane are excessively wide or too narrow in relation to the attachment pattern required to secure the roof membrane to the structure. Another advantage is that thefastener 14 does not penetrate theroof membrane 34 and thus symmetrical loading of thefastener assembly 10 is achieved and the seam is oriented such that forces exerted thereon are in a shear mode as opposed to a peel mode. - Another variation of this method is shown in
FIG. 8 whereroof membrane panels 38 are overlapped sufficiently to allow seaming and installing of thefastener 14 of thefastener assembly 10 through the roof membrane into theroofing membrane substrate 2 and theroof decking 4. Thesupplemental member 32 can be a circular (or any other shape) piece of roof membrane (or other compatible material) which is placed over thefastener assembly 10 and seamed at 39, 40 to theroof membrane 38. A drawback to this method is the significant number of individualsupplemental members 32 required to make theroof membrane 38 watertight. - The
roof membrane 38 can also be attached to the structure utilizing alinear fastener assembly 10 that is independent of the seam overlaps as shown inFIG. 9 . This method is similar to that discussed above and shown inFIG. 7 . However, instead of individual attachment patches, thefastener assembly 10 is installed through alongitudinal attachment strip 42. Thelongitudinal attachment strip 42 has a width which is sufficient to overlap thefastener assembly 10 and to allow areas forseams roof membrane 38. Panels of theroof membrane 38 are overlapped sufficiently to formseams longitudinal attachment strip 42 using one of the seaming methods discussed above. -
FIG. 10 shows another variation for attaching theroof membrane panels 38 which is similar to that discussed above and shown inFIG. 8 . This method also involves overlapping theroof membrane panels 38 sufficiently to allow seaming and installing thefastener assembly 10 through the roof membrane to theroof membrane substrate 2 androof decking 4. This method differs from the method discussed with respect toFIG. 8 in that theroof membrane panels 38 are attached utilizing a longitudinal attachment strip orcover strip 42 as shown and discussed with respect toFIG. 9 , rather than individual supplemental members. The linear fastening system is positioned over thefastener assembly 10 and is seamed at 39, 40 to themembrane panels 38. This method can minimize the number of patches required and can allow the use of automated welding devices. - While all of the methods discussed above and currently in use initially create a watertight system, they do not prevent subsequent damage that may be the result of cyclic loads resulting from wind or damage to the roof membrane due to natural phenomenon or abuse. There is a need in the art for fastening assembly that addresses these issues and prevents moisture or air from moving within the roof assembly, minimizing any weather related damage to the roof membrane substrate and roof decking.
- It is therefore an object of the invention to provide a mechanical attachment system for securing a roof membrane to a roof structure that creates a watertight system that reduces subsequent wind damage and other weather related abuse. It is a further object of the invention to provide a mechanical attachment system that prevents moisture or air from moving from the roof envelope to the seam channel or from the seam channel to the roof envelope.
- Accordingly, the present invention is directed to a roof seam fastener system, including a mechanical fastener member, for mechanically attaching a roof membrane to a roof structure, wherein the roof seam fastener system comprises a fastening assembly that creates a seal to either the roof membrane or a roofing substrate located directly below the fastening assembly. This fastening assembly also creates a seal against the mechanical fastener member. According to a first embodiment, the fastening assembly comprises a clamping plate having at least one washer laminated on one or both sides thereof. The fastener member includes a shaft extending through the clamping device and the at least one washer. The washer creates a seal with the roofing membrane and/or the roofing substrate as well as the shaft of the fastener member. According to a second embodiment, the fastening assembly comprises a clamping plate and a joining material positioned adjacent to the clamping plate. This joining material can comprise a field applied sealant or adhesive material. According to a third embodiment, the fastening assembly comprises a clamping plate having a washer laminated on one or both sides thereof or washers placed loosely on the top and or bottom of the plate. The fastening assembly may be positioned either above or below the roof membrane.

FIGS. 11 a-11 d which show the mechanical attachment system according to a first embodiment of the invention. In this embodiment, a fastening system, generally indicated as 50, comprises a clampingplate 52 and afastening member 54. Awasher 56 is positioned adjacent to the clampingplate 52 and is clamped between the clampingplate 52 and the material located directly below the clampingplate 52. The clampingplate 52 can be formed from a metal or plastic material or any other material having sufficient strength to perform a clamping function. Thewasher 56 can be formed from a flexible and/or compressible material, such as a rubber or plastic material or any other well known material used for forming washers. Thewasher 56 can be clamped between the clampingplate 52 and aroof membrane 58, as shown inFIGS. 11 a and 11 c. Alternatively, thewasher 56 can be laminated to the clampingplate 52 to form a washer/clamp plate assembly 57 prior to application to aroof membrane 58. Thewasher 56 can be laminated by any well known means, such as heat welding or the application of a separate adhesive material. Thewasher 56 forms aseal 65 to the underlying surface. This underlying surface can comprise either theroof membrane 58 or aroof substrate 59 in the situation illustrated inFIG. 14 wherein thefastening system 50 is attached between theroof membrane 58 and theroof substrate 59. - The
fastening member 54 can comprise a threaded fastener having ashaft 60. Thewasher 56 can include a preformedfirst aperture 62. A corresponding orsecond aperture 64 is also formed in the clampingplate 52. Theshaft 60 of thefastening member 54 extends throughapertures fastening system 50 to theroof membrane 58. Thefirst aperture 62 has a first diameter which is smaller in size than a second diameter ofsecond aperture 64. Through thisaperture 62, aseal 63 is created between thewasher 56 against thefastener shaft 60. As an alternative to the preformedaperture 62 in thewasher 56, thewasher 56 can be a solid member and theshaft 60 of thefastening member 54 penetrates thesolid washer 56 during installation. - A second washer can be applied to a top surface of the clamping
plate 52. This second washer allows for additional seaming or sealing against thefastener shaft 60. This second washer is also useful in situations where theroof membrane 58 is positioned above thefastening system 50, such as illustrated inFIG. 14 . In the event that the second washer does not seal against thefastener shaft 60, a grommet may be used directly beneath afastener head 70 of thefastening member 54. - A second embodiment is illustrated in
FIGS. 12 a and 12 b which show the use of a joiningmaterial 72 between the clampingplate 52 and theroof membrane 58. This joiningmaterial 72 creates aseal 90 against thefastener shaft 60 and theroof membrane 58. The joiningmaterial 72 can comprise a sealant, adhesive, tape, caulking and any other material capable of creating a seal. This joining material may be pre-applied to the clamping plate or it may be applied at the field during installation. - A third embodiment is illustrated in
FIGS. 12 c and 12 d which combine the features of the first and second embodiments. In this embodiment, thewasher plate 52 to form anassembly 74. The joiningmaterial 72 can be applied to one or both sides of the washer/clampingplate assembly 74 to seal thisassembly 74 to theroof membrane 58 and thefastening member 54. - The
fastening member 54 may be applied on site or, alternatively, thefastening member 54 may be formed as an integral component with the clamping plate/washer assemblies fastening member 54 may be any well known type of fastener capable of exerting a clamping force against the washer or sealant material. Some examples offastening members 54 include threaded fasteners, rivets, expansion bolts or interference fit fasteners that are driven into place. Some types of structural decks may require other specialty fasteners that also meet the clamping criteria. - The use of the
above fastening systems 50 and attachment methods used in combination with theroof membranes 58 result in a method that provides a redundant seal around the holes created in theroof membrane 58 by thefastening member 54. This redundant seal, when used in combination with any of the known double seaming, disc or strip fastened systems, as discussed in detail with respect toFIGS. 1-10 , prevents moisture or moisture laden air within the roof envelope of thefastening system 50. The use of theinventive fastening system 50 also prevents any moisture which enters the seam channel as a result of a faulty outside seam or a puncture over the seam channel from entering the roof envelope. -
FIGS. 13-15 show various applications of thefastening system 50 of the present invention for mechanically securing aroof membrane 58 to aroof substrate 59 androof decking 80.FIG. 13 shows an application of the invention for sealing a pair of overlappingroof membranes 58 wherein thefastening system 50 is positioned betweenedge portions roof membranes 58 and adouble seam fastening system 50.
