Description
RIGID INSULATED ROOFING SYSTEM
FIELD OF THE INVENTION
The present invention relates to a roofing system for a building in which rows of first rigid insulation panels are supported between mounting clips in a first layer, and rows of second rigid insulation panels are supported between mounting channels to span transversely over top of the first rigid insulation panels, between an upper supporting surface of the building structure below and exterior sheets of exterior finishing material of the roof thereabove.
BACKGROUND
In order to construct buildings which are more energy efficient, it is known to be desirable to provide more layers of insulation in walls and roofs where possible. Simply increasing the thickness of the insulation layer in a typical roof structure however can be difficult as the roof may lose structural integrity when using conventional techniques of assembling a roof.
United States Patent No. 8,677,718 by Joseph T Marshall discloses a mounting clip for use in an exterior building surface in which dimensional lumber is supported by the mounting clips in transverse layers to permit flexible batts of insulation to be layered between the layers of dimensional lumber. The resulting structure of transverse layers of dimensional lumber are not well suited for use with rigid insulation which cannot conform about the shape of the dimensional lumber.
SUMMARY OF THE INVENTION
According to one aspect of the invention there is provided a rigid insulation roofing system for a building including a plurality of main structural members spanning over an interior of the building and an upper supporting surface spanning an outer side of the main structural members, the roofing system Date Recue/Date Received 2023-03-28

3 connected between top and bottom mounting flanges provides a minimal thickness between adjacent rows of rigid insulation panels. The compressible nature of a typical installation panel formed of rigid, yet resilient foam material readily permits the thin sheet metal forming the upstanding flanges to be somewhat recessed into the edges of the rigid foam panels by lightly compressing the foam material against each upstanding flange. Accordingly, adjacent rows of the rigid insulation material within each row can be snuggly abutted with one another, so as to be separated only by the thickness of the upstanding flanges. Orienting the mounting channels to span transversely to the orientation of the upstanding flanges of the mounting clips also assists in orienting the seams between rows of first rigid insulation panels to be oriented transversely to the seams of the second rigid insulation panels to further minimize any areas in the roof through which heat can leak.
Preferably the rows of the first rigid insulation panels are separated only by a thickness of the upstanding flanges of the mounting clips, and the rows of second rigid insulation panels are separated only by a thickness of the upstanding flanges of the mounting channels. In this manner, cross bracing support is provided to the mounting clips primarily by the first rigid insulation panels and to the mounting channels primarily by the second rigid insulation panels.

6 DETAILED DESCRIPTION
Referring to the accompanying figures, there is illustrated a building roofing system generally indicated by reference numeral 10. The roofing system can be installed on a new building or retrofit over top of the roof of an existing building. In addition, the roofing system is applicable to various types of substructures according to the various embodiments described herein. The common features of the various embodiments will first be described.
Typically, the building includes a substructure including main structural members 12 spanning over an interior of the building between walls at opposing sides of the building, and an upper supporting surface 14 above the main structural members upon which roofing materials can be supported to form the exterior of the roofing structure.
The roofing system 10 according to the present invention is assembled in layers over top of the upper supporting surface of the building. Typically, an ice shielding layer 16 is initially installed directly over the upper supporting surface in the form of ice shielding material dispensed from rolls in adjacent rows with overlapping seams to form a uniform layer fully spanning over the upper supporting surface of the building. The material of the shielding layer 16 acts as a moisture barrier.
A plurality of mounting clips 18 are mounted onto the upper supporting surface of the building by fastening to the structure of the building therebelow through the material of the shielding layer 16. Each mounting clip includes a bottom flange 20 lying generally horizontally to define the bottom end of the mounting clip which receives fasteners therethrough for securing the mounting clip to the supporting structure of the building therebelow.

Referring to the accompanying figures, there is illustrated a building roofing system generally indicated by reference numeral 10. The roofing system can be installed on a new building or retrofit over top of the roof of an existing building. In addition, the roofing system is applicable to various types of substructures according to the various embodiments described herein. The common features of the various embodiments will first be described.
Typically, the building includes a substructure including main structural members 12 spanning over an interior of the building between walls at opposing sides of the building, and an upper supporting surface 14 above the main structural members upon which roofing materials can be supported to form the exterior of the roofing structure.
The roofing system 10 according to the present invention is assembled in layers over top of the upper supporting surface of the building. Typically, an ice shielding layer 16 is initially installed directly over the upper supporting surface in the form of ice shielding material dispensed from rolls in adjacent rows with overlapping seams to form a uniform layer fully spanning over the upper supporting surface of the building. The material of the shielding layer 16 acts as a moisture barrier.
A plurality of mounting clips 18 are mounted onto the upper supporting surface of the building by fastening to the structure of the building therebelow through the material of the shielding layer 16. Each mounting clip includes a bottom flange 20 lying generally horizontally to define the bottom end of the mounting clip which receives fasteners therethrough for securing the mounting clip to the supporting structure of the building therebelow.
Each mounting clip further includes an upstanding flange 22
7 perpendicularly oriented relative to the bottom flange to extend generally vertically upward from one side edge of the bottom flange to define the overall height of the mounting clip between the top and bottom ends thereof. A top flange 24 extends horizontally outward from the top end of the upstanding flange 22 so as to be parallel and spaced apart from the bottom flange while extending laterally outward from the upstanding flange in an opposing direction relative to the bottom flange such that the overall shape of the mounting clip is generally Z shaped. The top flange thus defines the top end of the mounting clip to which subsequent components of the roofing system are secured as described in further detail below. Each mounting clip is formed of a single sheet of sheet metal which has been cut and folded into the desired shape.
The mounting clips 18 are mounted in rows extending across the roof in the longitudinal direction of the roof. Within each row, the mounting clips are longitudinally spaced apart from one another and oriented such that the upstanding flanges 22 of all the mounting clips within a common row lie within a generally common vertical plane oriented in the longitudinal direction. Adjacent rows are spaced apart from one another in the lateral direction of the building.
A first insulating layer formed of first rigid insulating panels 26 are mounted onto the top side of the shielding layer 16 to span the full height Of the mounting clips such that the bottom flanges 20 lie flat against the bottom faces of the first rigid insulating panels 26 and the top flanges 24 lie flat against the top faces of the first rigid insulating panels 26. The first rigid insulating panels 26 are generally rectangular in shape so as to be elongate in the longitudinal direction of the building.
The panels 26 typically have a width in the lateral direction corresponding to the width between two adjacent rows of the mounting clips to fully span the width between the .. upstanding flanges 22 of the corresponding adjacent rows of the mounting clips.

A first insulating layer formed of first rigid insulating panels 26 are mounted onto the top side of the shielding layer 16 to span the full height Of the mounting clips such that the bottom flanges 20 lie flat against the bottom faces of the first rigid insulating panels 26 and the top flanges 24 lie flat against the top faces of the first rigid insulating panels 26. The first rigid insulating panels 26 are generally rectangular in shape so as to be elongate in the longitudinal direction of the building.
The panels 26 typically have a width in the lateral direction corresponding to the width between two adjacent rows of the mounting clips to fully span the width between the .. upstanding flanges 22 of the corresponding adjacent rows of the mounting clips.

8 Within each longitudinally extending row, a plurality of the panels 26 are abutted in series with one another to form a generally uniform layer. Adjacent rows of the panels 26 are similarly abutted so as to be separated only by the upstanding flanges of the mounting clips between adjacent rows. The rigid insulating panels comprise a rigid foam material commonly used for building insulation having a slight degree of resiliency when compressed by the thickness of the sheet-metal forming the mounting clips such that the panels 26 can be snuggly abutted to opposing sides of each upstanding flange with the flanges being slightly recessed into the resilient compressibility of the foam material so that adjacent rows of the foam material can also be substantially abutted with one another with minimal gaps therebetween.
The foam material forming the panels 26 has sufficient rigidity that the foam panels provide the primary cross bracing support between adjacent rows of the mounting clips when fully spanning the lateral width between mounting clips of adjacent rows.
When installing the panels 26, typically only a first row of mounting clips are mounted onto the upper supporting surface of the building structure followed by a corresponding first row of panels 26 abutted against the mounting clips. A
subsequent row of mounting clips can then be snuggly mounted against the other side of the row of panels 26, followed by a subsequent row of panels 26. Installation proceeds laterally across the width of the building in a similar manner with each row of mounting clips being installed in abutment against a previously installed row of insulating panels.
The roofing system further includes a plurality of mounting channels 28 which are mounted to extend over top of the first rigid insulating panels 26 of the first insulating layer in a lateral direction of the building such that each mounting channel 1r

Installation proceeds laterally across the width of the building in a similar manner with each row of mounting clips being installed in abutment against a previously installed row of insulating panels.
The roofing system further includes a plurality of mounting channels 28 which are mounted to extend over top of the first rigid insulating panels 26 of the first insulating layer in a lateral direction of the building such that each mounting channel 1r
9 extends perpendicularly across a plurality of rows of mounting clips. Each mounting channel is typically supported so as to extend across one mounting clip of each of the rows of mounting clips across which the mounting channel extends to permit fastening of the mounting channel to the top flange 24 of each mounting clip across which the mounting channel extends, Each mounting channel 28 comprises a uniform Z shaped profile which is uniform along the full length of the mounting channel extending in the lateral direction across the roof. More particularly, each mounting channel includes a bottom flange 30 which is horizontally oriented to define the bottom end of the mounting channel for mounting flat against the top flanges of the corresponding ones of the mounting clips for fastening between the mounting channel and the mounting clips respectively.
Each mounting channel further includes an upstanding flange 32 extending upwardly from one side of the bottom flange in perpendicular relationship therewith to extend vertically upward and define the overall height of the mounting channel between top and bottom ends thereof. A top flange 34 which defines the top end of the mounting channel extends laterally outwardly from one side of the upstanding flange opposed from the bottom flange to form the Z shaped profile.
The top flange is a horizontal flange oriented perpendicularly to the upstanding flange and parallel to the bottom flange therebelow. One or more mounting channels may be abutted in series across the lateral width of the building within each row of mounting channels.
A second insulating layer is formed by a plurality of second rigid insulating panels 36 formed of similar material to the first rigid insulating panels 26, but being reduced in height relative to the first insulating layer. The height of the panels forming the second layer correspond substantially to the full height of the mounting channels 28 such that the top flange 34 of the mounting channels lies flat against the top surface of the second rigid panels and the bottom flange of the mounting channels lies flat against the bottom face of the second insulating layer.
5 The second rigid insulating panels 36 are rectangular in shape so as to be elongate in the lateral direction of the building for mounting in laterally extending rows between adjacent ones of the mounting channels 28. Within each row, a plurality of the panels 36 are abutted in series with one another to form a uniform layer of material. The panels 36 having a width which spans a full width between two adjacent
Each mounting channel further includes an upstanding flange 32 extending upwardly from one side of the bottom flange in perpendicular relationship therewith to extend vertically upward and define the overall height of the mounting channel between top and bottom ends thereof. A top flange 34 which defines the top end of the mounting channel extends laterally outwardly from one side of the upstanding flange opposed from the bottom flange to form the Z shaped profile.
The top flange is a horizontal flange oriented perpendicularly to the upstanding flange and parallel to the bottom flange therebelow. One or more mounting channels may be abutted in series across the lateral width of the building within each row of mounting channels.
A second insulating layer is formed by a plurality of second rigid insulating panels 36 formed of similar material to the first rigid insulating panels 26, but being reduced in height relative to the first insulating layer. The height of the panels forming the second layer correspond substantially to the full height of the mounting channels 28 such that the top flange 34 of the mounting channels lies flat against the top surface of the second rigid panels and the bottom flange of the mounting channels lies flat against the bottom face of the second insulating layer.
5 The second rigid insulating panels 36 are rectangular in shape so as to be elongate in the lateral direction of the building for mounting in laterally extending rows between adjacent ones of the mounting channels 28. Within each row, a plurality of the panels 36 are abutted in series with one another to form a uniform layer of material. The panels 36 having a width which spans a full width between two adjacent
10 rows of the mounting channels 28 such that each adjacent row of panels 36 is separated only by the thickness of the sheet-metal forming the upstanding flanges 32.
Each mounting channel is formed of rigid sheet-metal which is cut and folded to define the desired shape of the channel similarly to the formation of the mounting clips.
Similarly, to the first insulating layer, the rows of panels 36 forming the second insulating layer and the mounting channels 28 are installed together by installing a first row of mounting channels 28 followed by a first row of second rigid insulating panels 36 abutted snuggly against the upstanding flanges 32 of the first row of mounting channels. A subsequent row of mounting channels 28 are then installed against the previously installed row of panels 36, followed by a subsequent row of mounting channels. Installation continues row by row across the full length of the building in the longitudinal direction such that adjacent rows of the second rigid insulating panels are separated only by the sheet metal thickness of the upstanding flanges of the mounting channels.

The roofing system further comprises a heat radiating barrier layer 38
11 formed of a heat radiating material. More particularly, the material of the barrier layer comprises flexible sheets of material which are typically dispensed from rolls. The sheet of material includes a fibrous insulating core with a metallic foil material spanning both top and bottom faces of the fibrous insulating core. The insulating core .. spans most of the thickness of the barrier layer relative to the foil faces. Adjacent rows are mounted to span across the roof by closely abutting the insulating cores of adjacent rows such that laterally protruding flanges of the foil facing material are arranged to overlap the seams between adjacent rows of the core material. The seams between adjacent rows of the heat radiating material of the barrier layer .. remain unsealed to allow some breathability and moisture venting through the heat radiant barrier layer 38.
The roofing system further includes exterior sheets 40 of the roof finishing material fully spanning over the barrier layer 38. In the illustrated embodiment, the exterior sheets comprise standing seam roofing panels mounted to span transversely across the mounting channels 28 in the longitudinal direction of the building such that each roofing panel spans across a plurality of channels.
Conventional mounting clips for mounting into the seam of a standing seam roofing material are used by fastening the base of the standing seam mounting clips to the top flange 34 of respective ones of the mounting channels using suitable fasteners.
