Abstract
In a roof system having exceptional insulating value, high density polyurethane foam or extruded polystyrene is used to form molded panels of predetermined size, shape and ornamental configuration. A non-skid primer coat is applied to the top surfaces and sides of the panels at the time of manufacture. A fabric layer or polyester mesh may be embedded in the bottom of the molded foam panels to enhance adhesion characteristics. During installation, the panels are set in a layer of low rise foam adhesive that is applied to the underlying roof deck or other surface (e.g., plywood, concrete, roofing felts, or spray foam), thereby avoiding the use of penetrating fasteners while enhancing wind uplift resistance. The panels may include interlocking structure for side-by-side and/or overlapping installation. Edges of the foam panels that need to be cut for fitting at valleys, hips, ridges, etc. are repaired in the field using factory supplied fabric and coating. After complete installation of the panels, a final topcoat composition such as, but not limited to, acrylic epoxy, silicon, or polyurea is applied to seal the roof system and provide a select roof color and desired grade.
Description
- 1. Field of the Invention
- This invention relates to foam panel roof systems and, more particularly, to a roof system and method of fabrication and installation of foam roof panels without the use of penetrating fasteners.
- 2. Discussion of the Related Art
- In residential and commercial steep slope roof construction, roofing tiles or shingles are usually installed on top of roofing felts with the use of mechanical fasteners (e.g., nails). Typically, a layer of tar is first applied to the roof deck (e.g., plywood) in order to seal cracks and gaps. The roofing felts are applied using tin tags and nails that penetrate the felts, tar and roof deck. Thereafter, the tiles or shingles are installed using mechanical fasteners that also penetrate the entire roof structure. The use of penetrating fasteners for roof installations presents a number of concerns and potential problems. In particular, the use of a large number of mechanical fasteners penetrating the roof deck compromises the watertight integrity of the roof system. Moreover, spot attachment of tiles and shingles using mechanical fasteners results in limited strength against uplift forces experienced during high wind conditions, particularly hurricanes. Additionally, the weight of conventional roofing tiles, typically made of ceramic, cast concrete or clay, renders them extremely hazardous as projectiles in a hurricane.
- In the past, various foam roofing tiles or panels have been proposed as an alternative to conventional ceramic and/or cast concrete tiles or wood shingles. Many of these proposed roofing tiles and panels have a hard plastic outer shell and a foam core. Examples of foam roofing panels in the related art are disclosed in the U.S. Patents to: Gleason et al., U.S. Pat. No. 4,279,106; Gadsby, U.S. Pat. No. 3,899,855; Pavia, Jr., U.S. Pat. No. 5,125,805; and Kirkhuff, U.S. Pat. No. 4,065,899. All of these foam core roofing panels are designed for installation using penetrating mechanical fasteners, which presents the several problems noted above. Moreover, the foam core panel systems in the related art do not allow for easily repairing cut or damaged tiles at the installation site in a cost effective manner.
- The insulation methods used in conventional steep slope roof structures presents further problems and concerns. Typically, insulation is applied on the inside of the roof structure, under the roof deck, such as in a crawl space or attic. This has the effect of trapping heat between the roof deck and the roofing tiles. Over time, the high temperature below the tiles, as a result of trapped heat, causes premature failure of the roof system.
- Accordingly, in view of the many problems and concerns associated with roofing systems and installation methods in the related art, there remains an urgent and definite need for an improved roof system and method of fabrication and installation that eliminates the need of penetrating fasteners and improves insulating values and wind uplift strength, while remaining cost effective and esthetically appealing.
- Considering the foregoing, it is a primary object of the present invention to provide an affordable and architecturally appealing foam roof panel system and method of fabrication and installation for use in the residential and commercial steep slope roof market, and wherein the entire system is installed without the use of any penetrating fasteners.
- It is a further object of the present invention to provide a foam roof panel system and method of fabrication and installation that allows for ease of installation and field modifications to the foam roof panels.
- It is a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that provides for field finishes that allow the owner/customer the option of selecting the appropriate top coat covering, including color and grade, according to the customer's budget, personal preference and needs.
- It is still a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that provides exceptional insulating value while offering aesthetically pleasing panel designs.
- It is still a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that provides tremendous uplift strength and resistance to high wind forces, particularly during hurricanes.
- It is yet a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that is lightweight, stronger, and safer during hurricanes.
- It is still a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that provides a useful life that is considerably longer than conventional steep slope roof systems.
- It is yet a further object of the present invention to provide an improved foam roof panel system and method of fabrication and installation that is relatively easy to install, and easily repaired and maintained in the field in a cost effective manner.
- These and other objects and advantages of the present invention are more readily apparent with reference to the detailed description and accompanying drawings.
- The present invention is directed to a roof system and method of fabrication and installation for use on residential and commercial sloped roofs. The roof system includes individual panels molded with a high density polyurethane foam or extruded polystyrene. The panels are molded to predetermined sizes, shapes and ornamental configurations. The foam core of the roofing panels provides exceptionally high insulating values. During manufacture, a non-skid primer coat is applied to the top surfaces and sides of the panels. A coated wire mesh may be embedded in the mold, within the foam core, to provide additional strength and resistance to warping, thereby maintaining the shape of the panel configuration. A fabric layer or polyester mesh may be embedded in the bottom of the molded foam panels to enhance adhesion characteristics. Additionally, the bottom surface may be configured with grooves or other irregular surface patterns to improve adhesion. During installation, the panels are set in a layer of low rise foam adhesive that is applied to the underlying roof deck or other surface (e.g., plywood, concrete, roofing felts or spray foam), thereby avoiding the use penetrating fasteners while enhancing wind uplift resistance. Installation over spray foam, such as polyurethane spray foam or other approved foam insulation may be performed in conjunction with the use of deck leveling guides to minimize waviness and to maintain uniform foam insulation thickness over the underlying roof deck.
- The molded foam panels may be formed to include interlocking structure for side-by-side and/or overlapping installation. Edges of the molded foam panels that need to be cut for fitting at valleys, hips, ridges, etc. can be repaired in the field using factory supplied fabric and coating. After complete installation of the molded foam panels, a final topcoat composition such as, but not limited to, acrylic epoxy, silicon, or polyurea is applied to seal the roof system and provide a select roof color and desired grade.
- For a fuller understanding of the nature of the present invention, reference should be made to the following detailed description taken in conjunction with the accompanying drawings in which:

FIG. 12 is a cross-sectional view of the molded foam roof panel ofFIG. 11 illustrating a solar panel tray molded within the top of the roof panel for accommodating the solar cell. - Like reference numerals refer to like parts throughout the several views of the drawings.
- The roof system of the present invention is shown throughout the several views of the drawings and is generally indicated as 10. The
roof system 10 usesindividual roofing panels 20 that are molded with a high density polyurethane foam or extrudedpolystyrene foam core 22. Thepanels 20 are molded in various sizes, shapes and configurations according to the desired aesthetic appearance of the roof. The moldedpanels 20 may also be formed as ridge caps, as well as other accessory components for fitting at unique intersections of the roof, terminations with walls, valleys, hips, ridges, etc. Thefoam core 22 of theroofing panels 20 provides exceptionally high insulating values well beyond that of conventional roofing tiles and shingles. During manufacture, anon-skid primer coat 24, such as a cement acrylic coating composition, is applied to the top surfaces and side edges of the molded panels. To enhance the adhesion characteristics, thebottom side 26 of the moldedpanels 20 may be provided with a fabric layer orpolyester mesh 28 that is adhered to or embedded in thefoam 22. Alternatively, thebottom side 26 of the panels may be provided with a grooved or irregular surface configuration to allow for improved adhesion at installation. Thefoam core 22 may further be provided with a coated wire mesh 30 embedded within the foam core to provide additional strength and resistance to warping. The embedded wire mesh 30 helps to maintain the shape of the moldedpanel 20, particularly when the panel is formed in unique or unusual configurations. - The molded
foam panel 20 may be designed for overlapping installation as seenFIGS. 1 , 2 and 9. In this instance, thepanels 20 are formed to include interlocking structure on the engaging overlapping surfaces. Specifically, the overlapping periphery of the panels may be formed for notched, flush fitting and overlapping attachment of adjacent panels, as demonstrated inFIGS. 4 and 5 . In this instance, a rib or protrudingflange 44 along theedge 40 of one panel is adapted for interlocking receipt within a correspondingly configuredgroove 46 or channel formed in the overlappingportion 42 of the adjacent panel, as seen inFIGS. 3-5 . Alternatively, thepanels 20 may be formed for side-by-side interlocking engagement. In this instance, theside edge 50 of one panel is provided with a protruding rib ortongue 54 for interlocking receipt within a correspondingly configuredgroove 56 formed in theabutting side edge 52 of an adjacently positioned panel, as shown inFIGS. 6-8 . In order to cover the seam between the adjacently positioned panels, an overlappingpatch panel 20 a may be provided, as seen inFIG. 6 . In this instance, the top surface 60 of thepanels 20 where thepatch panel 20 a is to be attached may be recessed, so that when thepatch panel 20 a is installed, the top surface of the patch panel lies flush with a remaining top surface of the adjacent panels. - During installation, the molded foam panels are set in a layer low
rise foam adhesive 70. Referring toFIGS. 1 and 2 , installation of theroof system 10 of the present invention on asloped roof structure 100 is shown. Theroof structure 100 includes aframe 110, such as trusses, with aroof deck 120, such as plywood sheets, fastened to theroof frame 110. In this example of theroof system 10, aspray foam insulation 80, such as polyurethane spray foam, is applied to the plywood roof deck. In order to maintain uniform thickness of the layer ofspray foam insulation 80 over theentire roof deck 120, guide blocks 82 may be used. Specifically,elongate wood blocks 82 of desired height (e.g., 2″) are fastened to the top surface of theroof deck 120 prior to application of thespray foam insulation 80. The guide blocks 82 may be installed in transverse parallel rows spaced 2 to 3 feet apart. The layer ofspray foam insulation 80 can then be applied with the guide blocks 82 serving as a height indicator to maintain uniform thickness of the applied layer ofspray foam insulation 80 over theroof deck 120, while minimizing waviness commonly associated with spray foam installations. - The method of installation of the
roof system 10 of the present invention consists of setting the moldedfoam panels 20 in a layer of lowrise foam adhesive 70, as seen inFIGS. 1 , 2 and 9. The lowrise foam adhesive 70 may be applied over thespray foam insulation 80 or, alternatively, directly to plywood deck, concrete deck, roofing felts, or other membrane system. Use of low rise foam adhesive, or approved equivalent, provides optimal bonding of thepanels 20 to the roof, providing excellent uplift strength to resist hurricane force winds. - During installation, edges of the molded
foam panels 20 will need to be cut for fitting at valleys, hips, ridges, etc. The cut edges are repaired in the field using factory supplied fabric and coatings. After complete installation of the moldedfoam panels 20, including ridge caps and accessories at valleys, hips, ridges, etc., a final top coat composition is applied over the entire roof, coating all exposed surfaces of the panels. The top coat composition may include, but is not limited to, acrylic epoxy, silicon, or polyurea. The top coat composition is applied to seal the entire roof system and provide a select roof color and desired grade, according to the needs and budgetary constraints of the customer. -
FIGS. 10-12 illustrate a further embodiment of theroof panel 20 of the present invention, wherein the roof panel incorporates one or moresolar cells 90 on the top side of the panel.FIG. 12 shows a cross-section of the moldedfoam panel 20 including a recessedtray 92 for receiving asolar cell 90 that is anchored to the foam core. A protectivesolar glass 94 coverssolar cell 90 and is flush with the top surface of thepanel 20.FIG. 11 illustrates a moldedfoam panel 20 incorporating a plurality ofsolar cells 90 within in recessedtrays 92, as shown inFIG. 12 , with each of thesolar cells 90 electrically connected in series byconductors 96 extending through the foam core. Male and female 97, 98 connectors are provided at opposite ends of thepanel 20 for electrical connection with adjacently installed panels. - While the present invention has been shown and described in accordance with preferred and practical embodiments thereof, it is recognized that departures from the instant disclosure are fully contemplated within the spirit and scope of the invention.
