SYSTEM OF PLACEMENT OF SHINGLES ON A ROOF, A PLURALITY OF SHINGLES THUS PLACED, AND A ROOF WITH SUCH SHINGLES THEREON
A system of placement of adjacent roofing shingles on a roof is provided, whereby the horizontal spacing of adjacent shingles, the vertical placement of shingles, and the proper angular orientation of shingles is provided, due to a system of indicia on a visible upper surface of the shingles. A plurality of adjacent appropriately oriented shingles and appropriately placed shingles are provided, as is a roof having a plurality of shingles laid up thereon in courses.
The present invention deals with the art of placing generally rigid simulated slate, tile or wood shake shingles on a roof. Generally, such shingles are of the rigid type, simulating slate, tile, or wood shakes.
It is desirable in placing shingles on a roof, to properly space adjacent shingles from one another, to allow for expansion and contraction with variations in temperature, and to properly align adjacent shingles so that shingles in the same course have upper and lower edges that are aligned with adjacent shingles in that course, and such that adjacent shingles in a given course are spaced the same distance from each other between the upper and lower edges of the shingles, rather than being cocked at an undesirable angle, all to assure that the visual appearance of the roof is that of a generally uniform, consistent shingle placement, for aesthetic purposes.
THE PRESENT INVENTIONThe present invention is directed to providing a system of placement of adjacent roofing shingles on a roof, such that the placement of adjacent shingles, when laid up on a roof, are in accordance with a predetermined desired placement as to lateral spacing, vertical spacing and alignment.
SUMMARY OF THE INVENTIONIn accordance with the present invention, a system of placement of adjacent shingles is provided based upon visual indicia that appear on the top surfaces of the shingles.
It is therefore an object of this invention to provide a system of placement of adjacent roofing shingles of the real or simulated tile, slate, or shake types, on a roof, such that the placement of adjacent shingles, when laid up on a roof, is in accordance with a predetermined desired placement as to lateral spacing, vertical spacing, and angular alignment.
It is another object of this invention to accomplish the above object, while providing a plurality of adjacent shingles disposed on a roof.
It is a further object of this invention to provide a roof having a plurality of shingles of the type described above, laid up in courses in accordance with the system described above.
Referring now to the drawings in detail, reference is first made to
Thus, visual indicia are provided on the top surfaces of the shingles. Proper alignment of the visual indicia or markings provide information as to whether or not adjacent shingles are appropriately spaced apart to accommodate thermal expansion and contraction, as to whether or not the shingles are vertically spaced so that upper edges of adjacent shingles are appropriately aligned, as to whether or not lower edges of adjacent shingles are properly aligned, and as to whether or not side edges of adjacent shingle are properly aligned, as well as to have appropriate aesthetic effect in giving the appearance of an installation of a natural slate, tile or shake product.
Accordingly, a synthetic, generally rigid or substantially rigid shingle 11 is provided having an outer or top surface 12, upper and lower edges 13 and 14, respectively, left and right edges 15 and 16 respectively, a bottom surface 17, with or without appropriate relief 18 or the like in the upper surface 12 thereof, in order to provide the appearance of and simulate natural materials.

Angled construction lines 27 and 28 are shown overlying the shingles 11 of

Referring now to the illustrations of
With reference to the spacing 48 between the shingles 11 illustrated in
It will thus be seen that one can visually sight along both angled indicia lines and horizontal indicia lines on the outer, upper surfaces of the shingles 11, in order to determine whether the alignment of edges of the shingles is appropriate, whether the lateral spacing is appropriate, and/or whether the vertical spacing is appropriate.
With reference now to
The construction lines 50 and 51 in the illustration of
In
However, with reference to
Thus, selection of the appropriate pair of sight lines on two adjacent shingles can provide a tool whereby the same shingle may be used with different controlled spacings, with the spacings being controlled by proper selection of the sight lines.
It will thus be understood that the broken lines indicate improper spacing or improper vertical or angular alignment, and visual bends that might appear along a sight line would indicate an undesirable canting or angular placement of one shingle relative to an adjacent shingle.
Furthermore, placement of the indicia at different positions vertically along a shingle can provide an indication of desired exposure length of the weather surface of the shingle, by indicating conformance with a proper predetermined vertical placement of one shingle relative to an adjacent shingle.
The indicia markings described above can be provided on the top surface of the shingle by a variety of techniques. Such techniques could include printing, stamping, embossing, branding, etching, coating, molding, and the like, or any of the above. In the case of molding, complex shapes that would be difficult to de-mold would preferably be avoided, in order to simplify the mold designs and processing of the shingles.
It will thus be understood that this invention provides an advantage in properly spacing shingles, that includes an ease of installation by simplifying spacing and alignment of the shingles, and ease of molding because the avoidance of extra components or parts or shapes that might otherwise cause undesirable complications in molding or de-molding.
It will be apparent from the above that various modifications may be made in the details of the markings, and or construction of the shingles in accordance with this invention, all within the spirit and scope of the invention as defined in the appended claims.
