Description
ROOFING PANEL SYSTEM
Field of the Invention This invention relates to roofing panels which can be used to construct a weather-resistant roof without the use of shingles or similar coverings. The weather-resistant roof may be an original roof or a replace ment/repair of an original roof. The roofing panels comprise a wood product sheathing panel which has been coated on one side with roofing granules which are bonded to the sheathing panel with a weather-resistant adhesive~
Background of the Invention Various products and methods are known for roofing houses and other buildings. Although the known systems differ in their details, they typically involve cover-ing the roof supports with boards or sheathing panels (e.g. plywood or waferboard)~ The method o~ attachment is usually with fasteners such as nails or staples or a suitable construction grade adhesive or a combination of such techniques. After the roof supports are covered, the boards or sheathing panels are then covered with a moisture barrier such as a treated felt paper and the resulting surface is then covered with shingles~ roll-roofing, tar or the like to thereby achieve a weather-resistant roof~
Such techniques involve a significant amount of on-site labor and may involve different skilled trades.
Consequently, there is an incentive to develop roofing systems that can be more economically installed for an original roof and for roof replacement and repair.
Summary of the Invent_ n Thus, in accordance with one aspect of the invPn-tion, there is provided a roofing panel for constructing a roof, said roofing panel comprising:
(a) a sheathing panel made of wood, said sheathing ,~
8~
-la-panel having first and second sides;
(h) roofing granules adhesively bonded to substan-tially said entire first side of said sheathing panel with a weather-resistant polyurethane resin;
and ~c) said roofing panel being substantially fr~e of roofing granules within a narrow border along at leas~ one edge of said first side of said sheathing panel, wherein when two roofing panels are abutted to construct a roof, said narrow border of each of said roofing panels are adjacent, wherein said narrow borders may be subsequently treated to form the roof.
In accordance with another aspect of the invention;
there is provided a method of making a one-step roofing panel comprising the steps of:
(a) coating one side of a wood product sheathing panel with a weather resistant adhesive;
(b) applying roofing granules to the adhesive coated sheathing panel to thereby bond the granules to the sheathing panel when the adhesive cures;
and (c) keeping a narrow border along at least one margin of said sheathing panel substantially free of roofing granules which are adhesively bonded to said panel, wherein when two roofing panels are abutted to construct a roof, said narrow border of each of said roofing panels are adjacent, wherein said narrow borders may be subsequently treated to form the roof.
In accordance with still another aspect of the invention, there is provided a method of constructing a weather resistant roof without the use of shingles, said method comprising the steps of:
(a) attaching a first roofing panel to the roof supports, said roofing panel consisting essentially of a wood product sheathing panel to which roofing -lb-granules have previously been adhesively bonded to;
(b) positioning and attaching a seeond of sald roofing panels to said roof supports, said second roofing panel abutting said first panel, each panel having a narrow border along said abutting edges which is substantially free of roofing granules, each panel having one end that overhangs a facia board, said one end having an end side and an underneath side coated with a weather resistant adhesive;
(c) sealing the seam between the adjacent roofing panels by caulking; and (d) sealing the underneath edge to the facia board by caulking.
The present invention is based upon the discovery of an alternative roofing system in which a sheathing panel made of wood (e.gO plywood or waferboard) is precoated with roofing granules that have been adhesive-ly bonded to substantially one entire side of the sheathing panel. A typical sheathing panel of this type will have nominal dimensions of from 4 feet by 8 feet up to as much as 8 feet by 2~ feet, or even larger. By using pre-coated sheathing panels of tnis type, a finished roof can be obtained in essentially one step by merely fastening these roofing panels to the roof supports and then sealing the joints between adjacent roofing panels.
If desired, the seams between adjacent panels can simply be coated with a suitable adhesive or caulk, with or without additional roofing granules being sprinkled over or mixed with the caulking or sealing material, or the seam may be covered with a suitable tape which may optionally and preferably be covered with matching roofing granules.
Although the roofing panels of the present inven-tion may be fabricated at any site away from the construc-tion site, it is convenient for the roofing panels to be fabricated at the place where sheathing panels are manufac-tured.
The roofing panels of the present invention may also be used to re-roof an existing roof that needs to be replaced by either placing the roofing panels over the existing shingles or tearing down the original roof to the sheathing and then using the roofing panels.

MATERIALS USED IN MAKING THE
ROOFING PANELS
The Sheathing Panels Although the present invention is broadly appli-cable to roofing panels which are made from any sheath-ing panel made of wood (e.g~ plywood~ waferboard, etc.) it will be described with particular reference to waferboard because waferboard is particularly well-suited for use in the present invention.
Although the basic manufacture of sheathing panels made of wood does not form an inventive part of the present invention, some description of the manufacture of wood panels other than plywood may be helpful to a full under-standing of the present invention.
The manufacture of wood panels from small wood frag-ments such as ch~ps, fibers and wafers is known and is different from the manufacture of multiple ply products such as ordinary plywood. Typically, the manufacture of panels from small wood fragments involves converting the wood into fragments suitable for the particular process being em-ployed, mixing the wood fragments with a suitable adhesive, and then molding the resulting mixture into the desired shape. Often the desired shape is in the form of large panels which are known to the trade by such diverse names as particle board, chip board, and waferboard depending upon the particular method and products from which the particular boards are made. Numerous variations of board-making processes exist and each type of wood fragment and each type of adhesive poses its own special processing needs and offers its own advantages and disadvantages The resulting wood panels have numerous applica-tions depending upon their own characteristics such as their density, s~rength, water-resis~ance, and cost.
However, wood panels made from wood fragments have their own characteristic appearance which is different from that of solid wood boards and paneling.
In a classic method of manufacturing sheathing panels from wood wafers, de-barked logs are cut into standard lengths and then fed to a waferizer which typically con-tains a series of revolving knives which serve to cut thin ribbons of wood from the short logs. These ribbons of wood break into short lengths called '7wafers"~ The resulting wafers are dried and then mixed wi~h a suitable exterior adhesive (e.g. ~ess than 10 percent, usually less than 3 percent of ad~esive based upon the weight of the finished panel) and a wax (e.g. less than 3 percent, usually less than one percent of the wax solid based on the weight of the finished product). The wax is often used as an aqueous emulsion, typically 50 percent wax and 50 percent liquid.
This wafer/adhesive mixture is then used to form a mat by depositing the mixture over the surface of a caul until a preselected depth of the mixture is reached. Next, the resulting mat is pressed at an elevated temperature in a large heated hydraulic press until the mat has been com-pressed to the desired thickness and the adhesive has been set. The presses, which frequently have multiple press openings, are then opened and the large waferboard panels are removed. The panels are then allowed to cool and may be cut into smaller sizes or trimmed before or after cooling.
These waferboard panels, as well as other sheathing panels, have nominal thicknesses of 1/8 inch up -to 1 inch or more, usually l/4 inch to 3/4 inch. Panel sizes are usually 4 feet by eight feet or larger (e~g. 4 feet by 12 feet or 8 feet by 28 feet).
The Adhesives Any suitable adhesive can be used for the purposes of the present invention so long as it has the desired characteristic of weather-resistance. Suitable adhesives include one and two componen~ polyurethane systems~ epoxy resins of various types including the bisphenol epichlor-hydrin resins, asphaltic materials, and the like. If desired, the adhesives will optionally include various additives to improve their weather resistance or other properties such as conventional UV absorbers, fire re-tardants~ colorants, fillers, and the like.
Roofing Granules Any roofing granule may be used, although all do not serve with equal effectivenessO The granules may be smoothe or irregular in shape and may be made of organic or inorganic materials such as silicates (e.g~ sand), pulver-ized rock, glass beads or crushed glass beads, plastic or metal chips, etc.
The size of the roofing granules may vary widely, but for most applications granules having a maximum dimension of less than lO millimeters, usually less than 5 milli-meters, e.g. about 1-3 millimeters, will be acceptable.
Method of Making the Roofing Panels The method of making the roofing panels of the present invention can be understood by reference to the drawings.
As shown in Figure l, a roofing panel generally designated by the numeral l, comprises a sheathing panel 2 (e.g. waferboard). Typically the panel 2 is polygonal shaped for use on structures such as a geodesic dome and is rectangular shaped for structures as shown in Figure 2.
One side of the sheathing panel 2 is coated with roofing granules generally designated by the numeral 3 which have been adhesively bonded to the sheathing panel 2 with adhesive 4.
If desired, the sheathing panels can be precoated or pre-treated wi-th preservatives, weather-resistan~
coatings, and active or latent adhesives (e.g. a solvent activated adhesive) before applying the roofing granules~
Although the roofing granules 3 and the adhesive 4 can be premi~ed before coating sheathing panel 2, it is generally convenient to first coat the sheathing panel 2 with adhe-sive 4 (e.g. coated to a depth of 5 to 100 mils, usually 10 to 40 mils) and then substantially completely cover the wet adhesive with rooflng granules 3 which become firmly bonded to the sheathing panel 2 when the adhesive 4 has cured or hardened.
Although an entire side of sheathing panel 2 can be coated with adhesive 4 and roofing granules 3~ it is preferred to fabricate the roofing panels 1 by a process in which roofing granules are substantially excluded within a narrow border 5 along at least one edge o the granule/adhesive coated sheathing panel 2~ However~ this border can be, and preferrably will be, coated with the adhesive 4. By substantially eliminating the roofing granules in this narrow border~ the narrow, granule-free border permits an effective sealing technique to be used for sealing the seams between two adjacent roofing panels.
The details of this sealing procedure are described under the heading "Methods of Constructing a Weather-Resistant Roof". Typically the width of this border will be on the order of 2-10 centimeters wide on roofing panels of a size of at least 4 feet by 8 feet.
Optionally and preferably, each roofing panel will be provided with at least two borders which are substan-tially free of roofing granules. Although granule free borders can be provided along all four edges of a rectan gular roofing panel, it is preferred to have such borders alony three edges, only, for reasons which are hereinafter explained. For other polygonal shaped roofing panels, such as those used for geodesic domes, it may be preferable to have some roofing panels with such a border along all of the edges. It ls understood that the shape oE each roofing panel is not limited to a rectangle o~ polygon, but may be any closed surface shape.
The cure time of the adhesives can be shortened by the use of heat or catalysts or both. Consequently~ a convenient time to apply the adhesive and roofing granules to a sheathing panel is at the conclusion of the manufac-turing process of the sheathing panel when the panel typically has some retained heat as a result of its own manufacturing process. For example, when waferboard is manufactured it is hot pressed as part of the manufacturing process. When the large sheets of waEerboard (e.g. slightly larger than 8 feet by 28 feet) are removed from the heated press/ they are trimmed and allowed to cool to room or warehouse temperature. Consequently, it is useful if the adhesive and roofing granules are applied to the waferboard panels while the panels still have some retained heat, thereby taking full advantage of the available energy. In manufact~ring process where the waferboard panels are allowed to cool, it is useful to preheat the panel before applying the adhesive and roofing granules. One method of heating is to use an infra-red radiation source.
Methods_of_Constructing a Weather-Resistant Roof In constructing weather-resistant roofs by use of the present roofing panels, it is convenient and prefer-red (but not necessary) to do one or all of the following:
(1) Fabricate the roofing panels in standard sizes so that their longest dimension is substantially equal to a number of different but commonly en-countered roof peak-to-eave distances (16 feet, 18 feet and 20 feet) of a standard 4-12 pi-tch roof.
Field of the Invention This invention relates to roofing panels which can be used to construct a weather-resistant roof without the use of shingles or similar coverings. The weather-resistant roof may be an original roof or a replace ment/repair of an original roof. The roofing panels comprise a wood product sheathing panel which has been coated on one side with roofing granules which are bonded to the sheathing panel with a weather-resistant adhesive~
Background of the Invention Various products and methods are known for roofing houses and other buildings. Although the known systems differ in their details, they typically involve cover-ing the roof supports with boards or sheathing panels (e.g. plywood or waferboard)~ The method o~ attachment is usually with fasteners such as nails or staples or a suitable construction grade adhesive or a combination of such techniques. After the roof supports are covered, the boards or sheathing panels are then covered with a moisture barrier such as a treated felt paper and the resulting surface is then covered with shingles~ roll-roofing, tar or the like to thereby achieve a weather-resistant roof~
Such techniques involve a significant amount of on-site labor and may involve different skilled trades.
Consequently, there is an incentive to develop roofing systems that can be more economically installed for an original roof and for roof replacement and repair.

Typically, the manufacture of panels from small wood fragments involves converting the wood into fragments suitable for the particular process being em-ployed, mixing the wood fragments with a suitable adhesive, and then molding the resulting mixture into the desired shape. Often the desired shape is in the form of large panels which are known to the trade by such diverse names as particle board, chip board, and waferboard depending upon the particular method and products from which the particular boards are made. Numerous variations of board-making processes exist and each type of wood fragment and each type of adhesive poses its own special processing needs and offers its own advantages and disadvantages The resulting wood panels have numerous applica-tions depending upon their own characteristics such as their density, s~rength, water-resis~ance, and cost.
However, wood panels made from wood fragments have their own characteristic appearance which is different from that of solid wood boards and paneling.
In a classic method of manufacturing sheathing panels from wood wafers, de-barked logs are cut into standard lengths and then fed to a waferizer which typically con-tains a series of revolving knives which serve to cut thin ribbons of wood from the short logs. These ribbons of wood break into short lengths called '7wafers"~ The resulting wafers are dried and then mixed wi~h a suitable exterior adhesive (e.g. ~ess than 10 percent, usually less than 3 percent of ad~esive based upon the weight of the finished panel) and a wax (e.g. less than 3 percent, usually less than one percent of the wax solid based on the weight of the finished product). The wax is often used as an aqueous emulsion, typically 50 percent wax and 50 percent liquid.
This wafer/adhesive mixture is then used to form a mat by depositing the mixture over the surface of a caul until a preselected depth of the mixture is reached. Next, the resulting mat is pressed at an elevated temperature in a large heated hydraulic press until the mat has been com-pressed to the desired thickness and the adhesive has been set. The presses, which frequently have multiple press openings, are then opened and the large waferboard panels are removed. The panels are then allowed to cool and may be cut into smaller sizes or trimmed before or after cooling.
These waferboard panels, as well as other sheathing panels, have nominal thicknesses of 1/8 inch up -to 1 inch or more, usually l/4 inch to 3/4 inch. Panel sizes are usually 4 feet by eight feet or larger (e~g. 4 feet by 12 feet or 8 feet by 28 feet).
The Adhesives Any suitable adhesive can be used for the purposes of the present invention so long as it has the desired characteristic of weather-resistance. Suitable adhesives include one and two componen~ polyurethane systems~ epoxy resins of various types including the bisphenol epichlor-hydrin resins, asphaltic materials, and the like. If desired, the adhesives will optionally include various additives to improve their weather resistance or other properties such as conventional UV absorbers, fire re-tardants~ colorants, fillers, and the like.
Roofing Granules Any roofing granule may be used, although all do not serve with equal effectivenessO The granules may be smoothe or irregular in shape and may be made of organic or inorganic materials such as silicates (e.g~ sand), pulver-ized rock, glass beads or crushed glass beads, plastic or metal chips, etc.
The size of the roofing granules may vary widely, but for most applications granules having a maximum dimension of less than lO millimeters, usually less than 5 milli-meters, e.g. about 1-3 millimeters, will be acceptable.
Method of Making the Roofing Panels The method of making the roofing panels of the present invention can be understood by reference to the drawings.
As shown in Figure l, a roofing panel generally designated by the numeral l, comprises a sheathing panel 2 (e.g. waferboard). Typically the panel 2 is polygonal shaped for use on structures such as a geodesic dome and is rectangular shaped for structures as shown in Figure 2.
One side of the sheathing panel 2 is coated with roofing granules generally designated by the numeral 3 which have been adhesively bonded to the sheathing panel 2 with adhesive 4.
If desired, the sheathing panels can be precoated or pre-treated wi-th preservatives, weather-resistan~
coatings, and active or latent adhesives (e.g. a solvent activated adhesive) before applying the roofing granules~
Although the roofing granules 3 and the adhesive 4 can be premi~ed before coating sheathing panel 2, it is generally convenient to first coat the sheathing panel 2 with adhe-sive 4 (e.g. coated to a depth of 5 to 100 mils, usually 10 to 40 mils) and then substantially completely cover the wet adhesive with rooflng granules 3 which become firmly bonded to the sheathing panel 2 when the adhesive 4 has cured or hardened.
Although an entire side of sheathing panel 2 can be coated with adhesive 4 and roofing granules 3~ it is preferred to fabricate the roofing panels 1 by a process in which roofing granules are substantially excluded within a narrow border 5 along at least one edge o the granule/adhesive coated sheathing panel 2~ However~ this border can be, and preferrably will be, coated with the adhesive 4. By substantially eliminating the roofing granules in this narrow border~ the narrow, granule-free border permits an effective sealing technique to be used for sealing the seams between two adjacent roofing panels.
The details of this sealing procedure are described under the heading "Methods of Constructing a Weather-Resistant Roof". Typically the width of this border will be on the order of 2-10 centimeters wide on roofing panels of a size of at least 4 feet by 8 feet.
Optionally and preferably, each roofing panel will be provided with at least two borders which are substan-tially free of roofing granules. Although granule free borders can be provided along all four edges of a rectan gular roofing panel, it is preferred to have such borders alony three edges, only, for reasons which are hereinafter explained. For other polygonal shaped roofing panels, such as those used for geodesic domes, it may be preferable to have some roofing panels with such a border along all of the edges. It ls understood that the shape oE each roofing panel is not limited to a rectangle o~ polygon, but may be any closed surface shape.
The cure time of the adhesives can be shortened by the use of heat or catalysts or both. Consequently~ a convenient time to apply the adhesive and roofing granules to a sheathing panel is at the conclusion of the manufac-turing process of the sheathing panel when the panel typically has some retained heat as a result of its own manufacturing process. For example, when waferboard is manufactured it is hot pressed as part of the manufacturing process. When the large sheets of waEerboard (e.g. slightly larger than 8 feet by 28 feet) are removed from the heated press/ they are trimmed and allowed to cool to room or warehouse temperature. Consequently, it is useful if the adhesive and roofing granules are applied to the waferboard panels while the panels still have some retained heat, thereby taking full advantage of the available energy. In manufact~ring process where the waferboard panels are allowed to cool, it is useful to preheat the panel before applying the adhesive and roofing granules. One method of heating is to use an infra-red radiation source.
Methods_of_Constructing a Weather-Resistant Roof In constructing weather-resistant roofs by use of the present roofing panels, it is convenient and prefer-red (but not necessary) to do one or all of the following:
(1) Fabricate the roofing panels in standard sizes so that their longest dimension is substantially equal to a number of different but commonly en-countered roof peak-to-eave distances (16 feet, 18 feet and 20 feet) of a standard 4-12 pi-tch roof.
(2) Manufacture the roofing panels in standard widths such as 4 feet or 8 feet wide so as to match the normal spacing of roof supports (e~g., 16 inches or 2 feet on centers~.
(3) Fabricate each standard size of roofing panel into two types, one type being pro~ided with a granule-free border along two adjacent margins of the panel and the other type being provided with three granule-free borders~
The method of constructing a weather-resistant roof according to the present invention can be understood by reference to Figure 2. Whlle the method shown and herein-after described is for cons~ructing an original roof, it is understood that the roofing panels may also be used to replace an existing roof.
As shown in Figure 2, a building generally design-ated by the numeral 20 has a series of roof supports 21.
A series of roofing panels are selected which have their longest dimension equal to the peak-to-eave distance of the building 20 and the panels are applied to the roof supports 21 with the end panel 22 having only two granule-free borders with the intermediate panels 23 being pro-vided with three granule free borders. The panels 22 and 23 are suitably attached to the roof supports with fast-eners such as nails or staples or adhesive or a combination of fasteners. After the roofing panels 22 and 23 are in place, the seams are sealed. The seams may be sealed by merely caulking the seams with any suitable caulking material (e.y. butyl rubber caulk~. Cosmetically, it is desirable if the seams are covered with additional adhesive to at least the full width of the granule free borders and then additional roofing granules of a matching color are sprinkled over the wet adhesive to thereby form a weather proof seal and cosmetically match the sealed seam with the remainder of the roofing panels 22 and 23. It is understood that in some cases the roofing panel may not fully extend from the peak to the eaves and it may be necessary to have more than one panel to cover such a distance~ This would therefore require a horizontal seam between two panels.

g As shown in Figure 3, the roofing panel 30 comprises a sheathing panel 33 coated wi-th roo~ing granules 35 which have been adhesively bonded to the sheathing panel 33 with adhesive 34. The roofing panel 30 has a granular free border 39. Two roofing panels 30 are applied to a roof support 31 and are suitably attached to the roof support 31 with fasteners such as nails or staples or adhesives or a combination of fastners. The seam between the roofinq panels 30 is then sealed. For convenience and weather~
ability, it is preferred to seal this seam with an adhesive coated tape 37 which is placed over the seam and bonded to the roofing panel 30 within the granular free borders 39.
Desirably, the tape 37 will be precoated on one side with matching roof granules 38 and on the other side with a contact adhesive 32 covered with a suitable release film~
If the tape has not been precoated with roofing granules 38, it may be covered with additional adhesive and sprin-kled with additional granules to improve bc~h its appear-ance and weatherability. The same technique can be used at the roof peak, in valleys and at vents or chimneys.
By not having a granule free border on the panels along the eaves, no special treatment of the panels 22 and 23 is required along the eaves. However~ Figure 4 shows a preferred method of construction along the eaves.
A roofing panel designated by the numeral 43 comprises a sheathing panel 42. The sheathing panel 42 has a top side 44, an end 45 and a bsttom side 46. The top side 44, end 45 and a portion of the bottom side 46 proximate to the end 45 are coated with an adhesive coating 47 (e.g. poly-urethane). Roofing granules 48 are coaked on the adhesive 47 on the top side 44. Roofing granules 48 may also be coated on the end 45 and a portion of the bottom side 46 proximate to the end 45. The roofing panel 43 is suitably attached to the roof support 41 and facia board 49 with fasteners. The bottom side 46 is sealed to the facia board 49 by merely caulking the seam with any suitable caulking t~
material (e.g. butyl rubber caulk).
I~ is understood that there are numerous suitable methods of sealing the seams. For example, metal strips may be fastened over the seams to seal the seams.
One method of finishing the peak of a building is shown in Figure 5. Roofing panel 53 comprises a sheathing panel 52. The roofing panels 53 are suitably attached to the roof supports 51. One side of the sheathing pane~ 52 is coated with roofing granules 58 which have been adhe-sively bonded to the sheathing panel 52 with adhesive 55.
The roofing panel 53 has a granular free border 59. The bottom edge of the roofing panels 53 meet at the peak of the roof and form a dead space 50. The dead space 50 between the two roofing panels 53 is preferably filled with a suitable caulk 56, although this is not required. An adhesive coated tape 54 having a roofing qranular backing 58 is placed over the dead space 50 and bonded to the roofing panels 53 within the granular free borders 59~
Desirably, the tape will be precoated on one side with matching roofing granules and on the other side with a contact adhesive covered with a suitable release film. If the tape has not been precoated with roofing granules, it may be covered with additional adhesive and sprinkled with additional granules to improve both its appearance and weatherability. Alternately, the tape may be constructed such that the additional granules may be simply pressed into the tape itself and thereby held in placeO
A preferred method or finishing the peak of a building is illustrated in Figure 6. The roofing panel 63 compris-ing roofing granules 68 adhesively coated to the sheathing panel 62 by adhesive 65 are fastened to the roof support 61. Unlike the method as illustrated in Figure 5, wherein the two roofing panels 53 contact one another~ the roofing panels 63 are disposed by approximately the width of the base 70 of a ridge vent 60~ The ridge vent 60 is prefer-ably metal or plastic and is lightweight. Upper portion 71 $~i of the ridge net 60 has a screen 74, as shown in Figure 7, to allow air to flow in and out of the top of a buildingO
Flange 72 of the ridge vent 60, the roofing panel 63, and a perforated plastic lip 69 are fastened to the roof support 61 by a fastener 64. During a rain, the perforated plastic lip 69 deflects the wind and reduces the amount of rain blown into the building via the screen 74. The ridge vent 60 may be further sealed to the roofing panel 63 by a suitable caulking material 66.
Other modifications of the invention will be apparent to those skilled in the art in light of the foregoing description. This descr.iption is intended to provide specific examples of individual embodiments which clearly disclose the present invention. Accordingly, the inven~
tion is not limited to these embodiments or to the use of elements having specific configurations and shapes as presented herein. All alternative modifications and variations of the present invention which follows in the spirit and broad scope of the appended claims are included.
