Definitions
- the present invention relates to a low-cost, durable and highly aesthetic shingle for roofing. More particularly, the present invention relates to a durable and flexible fiberglass composition shingle for roofing which is particularly configured as a ridge cover for application to the ridges, hips, and rakes of a roof where generally planar sections of the roof surface angularly intersect. Like a comparatively thick wood shake, the configuration of the present shingle gives an appearance of depth and creates shadow lines at adjacent shingles, which appearance of depth and shadows are considered among the principal aesthetically pleasing aspects of a wood shake roof. On the other hand, the present shingle provides fire protection much better than conventional wood shakes, and even better than conventional organic asphalt composition roofing, as well as a lower weight and better durability than the latter.
- a conventional low-cost organic asphalt composition ridge cover is known in accord with U.S. Pat. No. 3,913,294, issued Oct. 21, 1975 to B. Freiborg.
- the Freiborg patent is believed to teach a cover for the hips, ridges, and rakes of a roof wherein the cover includes a body of sheet organic filamentary material or organic felt layered first on an outer face with saturant asphalt penetrating somewhat through the felt sheet as well as saturating into the filaments of the felt, and then additionally layered with on outer asphalt layer securing a cosmetic and abrasion-resisting outer coating of granular mineral material.
- the ridge cover of Freiborg is configured as an elongate trapezoid having a T-shaped slit extending along its length near the center thereof.
- Plural transverse score lines transect the upright of the T-shaped slit, and the ridge cover is back folded on itself at these score lines either two times or four times to provide a central thickening in the ridge cover.
- the asphalt material tends to be brittle, especially when cool, the ridge cover of Freiborg while warm during manufacturing is folded lengthwise with the granular material outward.
- This lengthwise fold both allows shipment of the ridge cover in a compact form, and insures that any bending along the lengthwise fold which occurs in the field preparatory to installation of the cover on a roof is in the direction of unfolding the ridge cover at this lengthwise fold.
- the shingle of Freiborg is frequently found at a job site and before being unfolded for installation to have been damaged in manufacture, packing, shipping, or handling and to have fissures or cracks in the layered asphaltic material, especially at the lengthwise fold.
- the layered construction and brittle nature of the asphaltic material apparently combine to result in a somewhat fragile ridge cover which frequently is damaged even before it can be installed on a roof.
- the conventional organic asphalt composition shingle provides a layered or non-uniform composition of relatively weak organic fibers, some of which are saturated by and/or embedded in a matrix of relatively strong and stiff, but sometimes brittle, saturant asphalt material.
- the cover of Freiborg may endure the limited unfolding or opening necessary in the field for installation on a roof.
- these conventional ridge covers may require that they be warmed in the field before they are opened for installation. Such opening or unfolding in the field, even though it is of a limited nature and is performed in the direction of greatest tolerance to folding, may crack and destroy the ridge cover taught by Freiborg if it is performed at a low temperature.
- inorganic composition roofing materials have been developed which are considerably more flexible, durable and fire resistant than the conventional asphalt composition roofing materials of organic felt layered with asphalt and mineral granules.
- these improved modern roofing materials include a sheet-like mat or felt of inorganic glass fibers with a layer of coating-grade asphaltic material partially impregnating the inorganic felt.
- the coating grade asphaltic material cannot saturate into the glass fibers of the felt. However, the asphaltic material does penetrate into and partially through the sheet of inorganic felt.
- the asphaltic material additionally may be filled, for example, with granite dust or other inert material to improve the resistance of the material to ultraviolet light, or may be filled and modified (or "blown") by a steam and hot air process which modifies the viscosity and melting point temperature of the asphalt. Still alternatively, the asphaltic material may include rubberizers to improve its flexibility and reduce its tendency toward brittle fracture.
- the inorganic felt is conventionally layered with the asphaltic material and the resulting composition of fibrous material and matrix asphaltic material is not materially uniform throughout its thickness. Like the older roofing materials, an additional layer of asphalt adheres granular material to the outer surface of the roofing material to provide coloration, abrasion, and weather protection.
- these improved modern roofing materials offer a considerably greater flexibility, durability, and fire protection than conventional organic felt roofing materials.
- These improved roofing materials provide a composite of inorganic glass fibers which are very strong in tension and have an initial limpness or flexibility, but which will not endure sharp bending. That is, these inorganic glass fibers will fracture if subjected to a sharp bend.
- the felt of glass fibers is layered with and forms an intermediate composite with a matrix of asphaltic material which itself may be conventionally brittle, or may preferably be modified to be somewhat flexible. Even though the glass fibers are brittle and will fracture if bent sharply, they are somewhat flexible for small deflections and distortions of the shingle, and their very high tensile strength somewhat offsets the brittleness of the asphaltic matrix material.
- fiberglass shingles have been widely adapted for roofing uses.
- flexibility of fiberglass shingles which contributes to their greater tolerance to being walked on, and to their greater ability to endure the give and take of a building roof with changes in temperature and moisture content of the underlying structure, for example, is not an unmitigated advantage.
- the greater initial flexibility of fiberglass shingles may contribute to a greater susceptibility to their being caught by wind and being lifted off the roof surface. With conventional flat shingles, this wind susceptibility is generally overcome with the use of an adhesive securing the free end of each shingle to an underlying portion of a shingle below. This underlying portion of the lower shingle is secured to the roof by adjacent roofing nails and retains the upper shingle via the adhesive.
- roofing practice has evolved to the use of fiberglass shingles on the planar portions or fields of a roof, and in some cases, to the additional use of asphalt composition ridge covers of organic felt as taught by Freiborg.
- this practice results in a roof system having a durable shingle on the fields and a less durable ridge cover. Consequently, some home owners who believe that they have a roof warranty of 20 or 30 years, or longer, which warranty would apply properly to the field shingles, may discover to their dismay that the shingle manufacturer's warranty is voided by the combination in the roof system of the shorter-lived organic asphalt composition ridge covers.
- the field shingles provide an Underwriters Laboratory Class "A" fire protection rating
- the conventional ridge covers do not provide any significant level of fire protection. Consequently, the fire protection of the roof system is seriously compromised by the presence of the conventional organic ridge covers.
- a formed high-profile ridge cover is presented by U.S. Pat. No. 4,920,721, (the '921 patent) issued May 1, 1990 to the co-inventors of the present invention.
- the '921 patent teaches a high-profile shingle which includes an elongate trapezoidal base of fiberglass mat fill-coated with asphaltic material, and provided with an outer coating of granular mineral.
- the shingle is provided with at least one lengthwise extending stiffener which helps overcome the initial flexibility of the fiberglass felt material while also resisting back bending of the shingle.
- a lengthwise generally obtuse bend is formed in the shingle, and a comparatively thick sealing member is provided adjacent the free end of the shingle to space it away from the roof structure or from an underlying shingle.
- the base inorganic felt material of the shingle according to the '921 patent has sufficient bend tolerance to allow the formation of the lengthwise bend, which generally forms an obtuse angle, but is otherwise is treated as a stiff structure which is not distorted from its planar configuration.
- the base material from which this shingle is formed would not conventionally be expected to tolerate the sharp back bends involved in forming a shingle as taught by Freiborg. It may be appreciated that the design of the shingle taught by the '921 patent uses conventional fiberglass shingle material to best advantage, while compensating for its shortcomings.
- a shingle according to the '921 patent is also somewhat expensive to make and ship. That is, both the stiffener and the sealing member represent separate pieces to be formed and united with the remainder of the shingle. Also, the comparatively thick sealing members take up space and to a certain extent prevent the shingles nesting together in a shipping box as might be desired.
- the present invention provides an improved shingle which is particularly configured for its use as a ridge cover.
- the shingle is formed of a base of fiberglass mat of felt with a fill-coat of impregnating asphaltic material especially modified to make it less brittle.
- the modified asphaltic material may be considered somewhat rubbery in comparison to the rather brittle asphaltic materials used by Freiborg, for example.
- the fiberglass felt and asphaltic material are combined in such a way as to provide a composition structure of inorganic glass fibers in an asphaltic matrix which is uniform substantially through the thickness of the ridge cover.
- the Applicants have discovered that the base of fiberglass mat impregnated with a fill-coat of the modified asphaltic material will also tolerate sharp back bending at least as well as or even better than the old organic asphalt composition material.
- the Applicants have unexpectedly discovered that a materially uniform composition of inorganic fibers in a modified asphaltic matrix may be folded and sharply bent back on itself in order to form a ridge cover superficially somewhat similar to the old structure of Freiborg.
- modified asphaltic material impregnating into the mat of glass fibers surrounds and supports these fibers such that the mat will tolerate sharp bending.
- the matrix of modified asphaltic material rather than itself being brittle, is somewhat rubbery and may distribute bending forces in the composite structure of the shingle rather than itself fracturing and concentrating bending forces on the glass fibers.
- An outer coating of granular mineral material is adhered to the base with an additional layer of the modified asphaltic material.
- the improved material from which the shingle is fabricated is not layered with brittle asphalt, but is fill-coated or permeated with a modified asphaltic material to provide a composite material which is materially uniform throughout its thickness, and which allows a durability and service life which the shingle of Freiborg could not match.
- the present improved shingle is configured, shaped, and dimensioned to offset any undesirable consequences which might result from the use of the improved material of construction with a flexible fiberglass mat including the less brittle and more flexible modified asphaltic material.
- the resulting shingle rather than being brittle at particular temperatures as is a conventional asphalt composition shingle, is comparatively flexible. Because the fibrous mat of the improved shingle tends toward initial flexibility, like other fiberglass shingles, and the impregnating layer of modified asphaltic material is also more flexible and less brittle than conventional asphalt material, the resulting shingle may be considerably more flexible than conventional asphalt composition shingles at any particular temperature.
- the improved shingle is configured with a decreased length and increased width. Consequently, the free end of the shingle does not extend as far from the nailed portion of the shingle and a decreased susceptibility to wind lifting results.
- FIG. 1 provides a fragmentary perspective view of a shingle embodying the present invention installed on a roof;
- FIG. 2 is an enlarged fragmentary perspective view of the shingle seen in FIG. 1;
- FIG. 2A is a fragmentary cross sectional view taken along line 2A--2A of FIG. 2 and viewed in the direction of the arrows;
- FIG. 3 provides a plan view of a pair of conventional shingles as they are generally disposed adjacent one another during shipping, and illustrating the nature and extent of fissuring and cracking sometimes encountered with the conventional shingles;
- FIG. 4 provides a plan view of a sheet of shingle material at an intermediate stage of manufacture.
- a roof 10 is seen to include a pair of generally planar and conventional shingle-covered inclined surfaces or fields 12, which intersect with one another at an inclined hip 14.
- the roof 10 includes a plurality of aligned and partially overlapping ridge cover members 16.
- ridge cover member 16 employed at the hip 14 may be used also at the ridges and rakes (not shown) of the roof 10.
- the ridge cover members 16 each include a chevron-shaped sheet-like upper portion 18 and a similar chevron-shaped sheet-like lower portion 20, which portions are connected by a thickened portion 22.
- the thickened portion 22 is thickened by repeated back folding of the sheet material, generally referenced with the numeral 24, from which the ridge cover 16 is formed. Because this sheet material 24 is generally in the range of from one-eight to three-sixteenth of an inch thick, and the thickened portion 22 is formed by back folding the material 24 either twice or four times on itself, the portions 18 and 20 define respective upper surfaces 26, and 28 which are spaced apart perpendicularly to the plane of the sheet material 24 by twice or four times the thickness of the sheet material 24.
- the upper surfaces 26, and 28 are spaced out of plane with each other by a dimension preferably in the range of from one-forth to three-forth of an inch.
- the upper portion 18 and lower portion 20 define respective longitudinal fold lines 30 and 32 which are similarly spaced apart from each other in a direction perpendicular to the fold lines.
- successive ridge cover members are installed upwardly along the hip 14 by nailing through the thickened portion 22 as is shown with the exposed nail heads 34 on one ridge cover, or alternatively, by nailing above the thickened portion 22 through the lower part of the portion 18.
- Each ridge cover 16 is installed with the lower portion 20 of each overlapping the upper portion 18 of the preceding ridge cover member to cover the nail heads exposed on this preceding cover member.
- a lower end edge 36 of each successive ridge cover member 16 extends slightly down-slope beyond the thickened portion 22 of the preceding ridge cover member. Consequently, the ridge covers 16 as installed on roof 10, provide a shadow, referenced on the drawing Figures with the numeral 38, falling on the lower portion 20 of the next lower ridge cover member.
- the existence and extent of the shadow 38 depends on the ambient lighting conditions, and that this shadow generally will be similar aesthetically to that at a hip of a wood shake roof.
- Each ridge cover 16 includes a felt or mat 40 of entangled fine-dimension inorganic glass fibers 40. Encompassing these glass fibers 40 is a fill-coating or impregnating mass of modified, or filled and modified asphaltic material referenced with the numeral 42. The material surrounds and bonds to the fibers 40 and forms a three dimensional matrix having a depth generally equal the thickness of the felt 40. On an upper or outer surface of the felt/matrix (40/42), is disposed a comparatively thin layer of additional modified asphaltic material 44, which secures a layer of protective granular mineral material 46 thereto.
- the modified or filled and modified asphaltic material 42 is composed of asphalt having at least three percent of a flexibility-improving elastomeric material added thereto.
- the flexibility-improving additive is styrene-butadiene-styrene (SBS) added to the asphalt at a seven percent by weight ratio.
- SBS styrene-butadiene-styrene
- the asphalt and SBS are combined in a high-power high-shear mixer/blender, and masticated with one another at a temperature of from 350 to 360 degrees F. While the seven percent loading of SBS has been found in actual practice of the present invention to give satisfactory results, the percentage of SBS may be increased up to about twelve percent, if desired.
- the asphaltic material 42 After being so modified to improve its flexibility, the asphaltic material 42 in forcefully impregnated into the felt 40 of glass fibers. A subsequent operation applies the layer 44 of additional asphaltic material and embeds the granular mineral material 46 in this layer while still hot. .[.A sheet roofing material conforming to the above specification is available from Herbert Malarkey Roofing Company, 3131 North Columbia Avenue, Portland, Oreg..].
- Another flexibility improving additive may be employed in the practice of the present invention.
- An alternative flexibility improving additive which is known to the Applicants is atactic polypropylene. This material may be added to natural asphalt in about the same percentages indicated above (i.e., three percent to twelve percent by weight), and will give good results, the Applicants believe.
- a sheet of the material 24 is shown in plan view at an intermediate step of the manufacture of the ridge cover 16.
- This sheet initially is planar and rectangular with upper and lower parallel edges 48 and 50, and parallel side edges 52.
- a triangular portion 54 of the sheet material 24 is trimmed away at each side to create new relatively angulated side edges 52'. Consequently, the sheet of material acquires a trapezoidal shape like the ridge covers 16.
- the sheet material 24 is slit to form successively oppositely angulated separation lines 56.
- the sheet material 24 defines plural oppositely-disposed work pieces (in the present case, five work pieces, although a different number of work pieces is equally possible) respectively referenced with the numerals 16a, 16b, 16c, 16d, and 16e.
- Each of these work pieces becomes one ridge cover member 16 upon completion of the manufacturing process.
- the work pieces 16a-16e are each of elongate trapezoidal shape. These work pieces 16a-16e have a length "L" in the range of from 21 and 3/4 inch to 24 and 1/4 inch.
- each work piece 16a-16e has a width "w" of from 5 inches to 8 inches, and this narrow end of the work piece which will form the upper portion 18 of the finished ridge cover has a length "l” of from 6 inches to 9 inches.
- each work piece has a width "W” of from 7 and 3/4 inches to 9 and 3/4 inches wide.
- a length-wise extending centrally located T-shaped slit 58 is formed in each work piece.
- the T-shaped slits each include an upright portion of the T-shape, referenced with the numeral 60 which is from 5 and 5/8 inches to 7 and 5/8 inches long, and a cross bar portion of the T-shape which is referenced with the numeral 62.
- An end 64 of the upright portion 60 away from the cross bar portion 62 defines one margin for the thickened portion 22, as will be seen.
- the work pieces 16a-16e each include plural spaced apart transverse score lines 66 which are aligned with one another in pairs on opposite sides of the upright portion 60.
- One pair of the score lines 66 are aligned with the end 64 of the upright portion 60 of the T-shaped slit 58.
- each is back folded on itself at the score lines 66 to create the thickened portion 22.
- the work pieces may be first folded double at the pair of score 66 lines aligning with the end 64 of the upright portion 60 with their upper surfaces together, and then be successively back folded in opposite directions at each successively adjacent pair of score lines.
- the present ridge cover members are depicted and described with the score lines 66 in order to clarify the formation of the ridge covers from the sheet material as depicted in FIG. 4, the Applicants have discovered that the remarkable and surprising flexibility and tolerance to back bending which is possessed by the present material of construction allows the ridge covers 16 to be formed without the score lines 58. While the work pieces are still back folded at each location indicated by the score lines, the actual formation of these score lines as a step in the manufacture of the ridge covers may be omitted. This elimination of the necessity to form the score lines 66 additionally reduces the costs of manufacture for the present ridge covers.
- FIG. 3 depicts the prior art ridge cover according to the Freiborg patent, it also illustrates the type and extend of cracking and fissuring which may be found in ridge covers made according to the conventional teaching of Freiborg. This type of cracking and fissuring may be present even before the covers are unfolded for their installation on a roof. Understandably, such cracked and fissured ridge covers may not be useable at all, or can not be expected to give a very long service life if they are used.
- the present ridge covers In contrast to the ridge covers of Freiborg, while the present ridge covers superficially appear similar structurally, they are considerably and surprisingly different so far as their structure, material uniformity through the thickness of the ridge cover, service life, durability, and fire protection are concerned.
- the present ridge covers are also particularly dimensioned differently than the conventional ridge covers to compensate for the greater flexibility of the ridge covers, and achieve a secure and wind-resistant installation on a roof.
- the surprising flexibility of the described material of construction also allows the present ridge covers to endure the sharp lengthwise bend which places them in to condition for compact shipment without the fissuring and cracking experienced with conventional ridge covers. Also, the preheating of the conventional ridge covers which has been necessary before they would endure unfolding to their installation condition is reduced or eliminated by the present invention. As a result, the sometimes heavy rate of damage in shipping, handling, and preparations for installation which was experienced with conventional ridge covers is drastically reduced by the present invention. Thus, yet another saving is realized out of this present invention, the lost expenses of shipping and handling damage-prone conventional ridge covers which because they are found to have been damaged prior to their installation on a roof are not suitable for installation at all.
- the inclination in the field while installing a roof is to make best use of the materials at hand.
- conventional ridge covers are found to be a little damaged they are frequently installed nonetheless.
- This inclination to use marginal materials, to compromise the integrity of the roof system as installed, and to perhaps further undermine the roof warranty of a home owner is decreased by the present invention.
- the present flexible ridge covers are not nearly so susceptible to damage in shipping and handling as are the conventional brittle ridge covers. Consequently, roofers in the field are provided with a flexible ridge cover not damaged in shipping and requiring less special care and handling in installation.
- the resulting integrity of the installed roof system is much improved.
- Home owners may enjoy the full 20 year, 30 year, or longer, warranty of their roof system, as well as an improved .[.Class "A",.]. fire rating for the entire roof.
- the present invention has been depicted, described, and is defined by reference to a particularly preferred embodiment of the invention, such reference does not imply a limitation on the invention, and no such limitation is to be inferred.
- the invention is capable of considerable modification, alteration, and equivalents in form and function, as will occur to those ordinarily skilled in the pertinent arts.
- the sheet like base of inorganic fibers could be woven rather than felted. While such a woven base material is not generally used in the roofing art because of its cost, it would provide a much stronger shingle and the invention could be practiced using such a base material.
- other elastomeric polymers could be used in modifying asphaltic material to improve its flexibility. The two flexibility improving additives mentioned herein are exemplary only.
