Definitions

  • This invention relates to the designs of multi-layer shingles.
  • it relates to multi-layer shingles having shiplap joints.
  • Asphalt roofing shingles have been in general use on roofs for nearly 100 years. They provide excellent water shedding characteristics to protect roofs from water leaks.
  • the shingles are installed on a roof and overlap each other in a way that water cannot leak through the joints of the shingles to the base board of the roof.
  • each course of shingles is horizontally offset, about 4" to 10", relative to the preceding course of shingles so that the joints of the shingles in a course do not line up with the joints of the shingles in the preceding or succeeding course.
  • each course of shingles overlaps the preceding course of shingles by more than 50% of the shingle width.
  • a shingle surface can be divided into two areas, called the "headlap portion” and the "exposure portion".
  • the headlap portion is the area of the shingle covered by the shingles of the succeeding (i.e. next higher) course of shingles
  • the exposure portion is the area of the shingle exposed to the environment. More overlapping area means less roof coverage area for the shingle.
  • the higher the ratio of the headlap portion to the exposure portion the higher the shingle cost per unit of roof coverage area is, because a larger overall shingle area is required to provide an amount of exposure which is equal to the roof coverage area.
  • the headlap to exposure ratio cannot (in the prior art) be reduced to less than one.
  • the invention provides a roofing shingle comprising: (a) a base layer having first and second longitudinally spaced-apart end edges defining between them a length for said base layer, said base layer also having laterally spaced-apart top and bottom edges defining a width for said base layer, said base layer having an upper surface, (b) a second layer laminated to said upper surface of said base layer, (c) said second layer having a first end portion inset from said first end edge of said base layer over at least a substantial portion of the width of said base layer, said first end portion being inset from said first end edge from a position adjacent said top edge of said base layer to a position at or near said bottom edge of said base layer, so that said first end edge of said base layer extends in a longitudinal direction beyond said first end portion of said second layer over said substantial portion of the width of the base layer to form a projecting end of said base layer, (d) said second layer having a second end portion extending longitudinally beyond said second end edge of said base layer over at least a
  • each shingle In conventional multi-layer asphalt roofing shingles, the typical size of each shingle is about 39 3/8" (long) x 13 1/4" (wide). Usually, such shingles are installed across the roof in horizontal courses, without overlapping any other shingles in the same horizontal course. However they overlap the shingles in the preceding course, as courses or rows are applied vertically up the roof. In addition, each course of shingles is installed with an offset horizontally to the preceding course, so that joints between the shingles in the same course do not line up with the joints between the shingles in the preceding course or succeeding course. In the aforementioned shingle, the typical exposure of the shingle is about 5 5/8" out of the 13 1/4" width of the shingle.
  • the headlap portion is usually the width of the shingle less 2", divided by 2, which yields the 5 5/8" exposure portion in the above example.
  • the headlap-to-exposure ratio of the shingle is 7 5/8" divided by 5 5/8" and is equal to 1.36.
  • the headlap-to-exposure ratio close to one or less than one. All portions of the vertical joint between horizontally adjacent shingles in the same course must either be placed on top of the shingles in the preceding course or be covered by the shingles in the succeeding course.
  • the inventor has realized that when multiple layer laminate shingles are used, they can be designed to provide a shiplap feature which can eliminate the restriction that the headlap-to-exposure ratio must be greater than 1. Once the restriction is removed, the headlap-to-exposure ratio can be reduced significantly. A smaller shingle width will then be required to provide the same amount of roof coverage area, or alternatively the same overall shingle width can provide a larger amount of roof coverage area.
  • a shiplap joint is the overlapping portion of two consecutive shingles in the same course after installation.
  • Shingle 10 includes a base layer 12 having longitudinally spaced-apart end edges 14, 16 which define between them the length of the shingle base layer, and laterally spaced-apart top and bottom edges 18, 20 which define between them the width of the base layer. (When the shingle 10 is laid, the top edge 18 will be at the top of the headlap portion and the bottom edge 20 will be at the bottom of the exposure portion.)
  • Shingle 10 also includes a second layer 24 , formed in the Figs. 1a, 1b embodiment by four individual tabs 26, 28, 30 , and 32 .
  • the number, spacing and size of these tabs is largely optional, except as will be explained. (For example, the tabs 26, 28, 30 and 32 can be of substantially equal size.)
  • the tabs 26-32 which can have various colors of granules applied to them, are laminated to the base layer 12 in conventional fashion, with slots 34 between the tabs 26-32 to provide an ornamental appearance.
  • one end tab 26 has an end edge 36 extending longitudinally beyond the end edge 14 of the base layer 12 by a first longitudinal offset indicated at 38 .
  • first longitudinal offset 38 is about 2" to 6".
  • the end edge 40 of the fourth tab 32 is inset from the end edge 16 of the base layer by a second longitudinal offset 42 which is preferably of the same longitudinal extent as offset 38 (although offset 42 can be slightly smaller or larger if desired).
  • end edges 36, 40 will usually not be straight, since they are cut to a shape such that the end edge 36 of one shingle, and the end edge 40 of its adjacent shingle, form one of the slots 34 when the shingles are installed on a roof.
  • the shingle 10 has at one end a projecting tab portion 44 and at the other end a projecting base layer portion 46 .
  • the projecting tab portion 44 will cover the projecting base layer portion 46 for adjacent shingles, thus forming a set of shiplap joints which cover any gaps between horizontally adjacent shingles in the same course. Therefore, no rain water can leak through the joints, even if the joints are neither placed on top of shingles in the preceding (lower) course nor covered by the shingles in the succeeding (next higher) course. Therefore, the headlap-to-exposure ratio no longer needs to be greater than 1.
  • the headlap width 48 of the double laminate shingle 10 is larger than 2", to provide sufficient overlapping area between successive courses of shingles to avoid rain water being driven up between the courses by high winds and leaking through in the headlap area.
  • the exposure portion of the shingle may be between 6" and 18".
  • the headlap-to-exposure ratio can be reduced from more than 1 to 1.0 or less, or (preferably) 0.5 or less.
  • the tab 26 which has the projecting portion 44 extends fully from the top edge 18 to the bottom edge 20 of the base layer 12 .
  • the vertical joint between horizontally adjacent shingles is fully covered (from top to bottom) by the projecting tab portion 44 .
  • the projecting tab portion 44 extend over the full width of the shingle, although it is desirable that it do so, or at least that it extend over most of the shingle width.
  • the tab 26 extend to a position adjacent (at or near) the top edge 18 of the base layer 12 .
  • the bottom edge of the tab 26 can be displaced slightly upwardly from the bottom edge 20 of the base layer 12 (e.g. for decorative purposes), but it should preferably be close to (e.g. within an inch or two of) the bottom edge 20 of the base layer 12 .
  • Fig. 2 shows portions of three courses of prior art shingles 50 laid on a roof (without any shiplap joints).
  • the prior art shingles 50 may each be assumed to be three units wide (i.e. high) and have vertical joints 52 between horizontally adjacent shingles.
  • joint 52-1 it will be seen that the top 1/3 of this joint (indicated at 52-1a and located in the headlap portion 54 ) will be covered by the succeeding course, and in addition the bottom third of the joint (indicated at 52-1c ) will be protected by the preceding course which is beneath it.
  • the middle third of the joint is exposed and will be penetrated by rain.
  • the shiplap joint can extend only a short distance above and below the middle third 52-1b of the joint 52-1 and will provide protection against rain penetration. However in practice this would not normally be sufficient to prevent wind driven rain penetration. Therefore it is preferred that the tab 26 having the projecting portion 44 extend from a position at or close to the top edge 18 , to a position at or close to, or at least not spaced too much above, the bottom edge 20 of the base layer 12 .
  • Figs. 3a, 3b show a double laminate shingle very similar to that of Figs. 1 a, 1b, and in which primed reference numerals indicate corresponding parts.
  • the second layer 24' is formed from a single sheet instead of from a plurality of individual tabs.
  • the second layer 24' contains cutouts or slots 34' extending from its bottom edge over part of its width to form decorative tabs, which can have various colors of granules applied thereto.
  • Figs. 4a, 4b show an embodiment which is the same as that of Figs. 3a, 3b except that a longitudinally extending narrow strip 60 (which forms a third layer) has been adhered on top of the headlap portion of the double laminate shingle, adjacent the top edge 18' .
  • the length of the narrow strip 60 can be equal to or less than the overall length of the second layer 24' .
  • the strip 60 does not affect the shiplap joint previously described, but when the shingles of Figs. 4a, 4b are installed on a roof, the butts of the shingles in each succeeding course will line up with the bottom longitudinal edges of the narrow strips 60 . Therefore these shingles after installation will to some extent have the appearance of more costly triple laminate shingles.
  • Figs. 5a, 5b show another design which is the same as that of Figs. 4a, 4b except that strip 60 has been omitted and a narrow strip 62 has now been adhered beneath the base layer 12', flush with the butt or bottom edge 20' of the base layer 12' .
  • the length of the narrow strip 62 can be equal to or less than the length of the base layer 12' and will provide the appearance of a more costly triple laminate shingle.
  • Figs. 6a, 6b and 6c show an embodiment similar to that of Figs. 5a, 5b except that the narrow strip or third layer 64 (similar to strip 62 ) is now irregular in shape, having wider portions 66, which project below the bottom edge 20' of the base layer 12' in selected locations as shown for projections 68 .
  • the projections 68 can be of desired width, e.g. 1/4 to 1/2 inch, or they can be of different widths, or they can be slanted, i.e. starting at zero projection and ending at 1/4 or 1/2 inch.
  • the projections 68 will normally have colored granules applied thereto (as will the remainder of the exposed portions of the shingles), but use of granules in the remainder of strip 64 is optional.
  • the locations for projections 68 are chosen to be aligned with tabs of the second layer, e.g. the second and fourth tabs 28', 32' , as shown in Figs. 6a, 6b. This again provides a more decorative appearance for the shingle, at relatively low cost.
