Description

BACKGROUND OF THE INVENTION

A residential and commercial roof generally serves utilitarian functions for building structures. The roof serves to keep moisture out of the structure and control the climate inside. The materials selected for construction of the external surfaces of the roof were likewise generally utilitarian. Tile, slate, wood, composite materials, and the like have traditionally been selected for roof construction due to concerns of cost and durability. The aesthetic properties of roof construction materials have generally taken a back seat.

Roofing products can be classified in three basic groups: shingles, roll roofing and underlayment. Shingles and roll roofing are typically outer roof coverings designed to withstand exposure to weather and the elements. In a typical roof installation, the underlayment is first laid on top of the roof deck, and then the outer roofing covering (e.g., shingles or roll roofing) is attached on top of the underlayment.

Asphalt, or “composite” shingles are a commonly used roofing material. Asphalt shingles may include an organic felt or fiberglass mat base on which an asphalt coating is applied. The organic felt or fiberglass mat base gives the asphalt shingle the strength while the asphalt coating provides resistance to weathering. An outer layer of mineral granules may also be applied to the asphalt coating to form a weather surface which shields the asphalt coating from the sun and provides additional fire resistance.

Composite shingles are typically manufactured as three tab shingles, laminated shingles, interlocking shingles, or large individual shingles. Even though composite shingles offer significant cost, service life, and fire resistance advantages, wood shingles are sometimes preferred due to pleasing aesthetic features, such as greater thickness as compared to composite shingles. Wood shingles may result in a layered look for a roof. Various composite shingles have been developed to provide an appearance of thickness comparable to wood shingles.

Roofs having composite shingles frequently have a dull or otherwise unpleasing appearance. Roofs are typically void of attention to architecturally appealing features. Current attempts to make roofs better looking and more interesting have been largely unsuccessful. There remains a long-felt need for a suitable means of creating a roof with an interesting appearance.

Preliminarily, it should be noted that certain terms used herein, such as for example above, below, upper, lower left and right, are used to facilitate the description of the invention. Unless otherwise specified or made apparent by the context of the discussion, such terms and other directional terms should be interpreted with reference to the figure(s) under discussion. Such terms are not intended as a limitation on the position in which the invention or components may be used. Indeed, it is contemplated that the components of the invention may be easily positioned in any desired orientation for use. Likewise, numerical terms such as for example “first”, and “second” are not intended as a limitation or to imply a sequence, unless otherwise specified or made apparent by the context of the discussion. The term “operatively connected” is understood to include a linking together of the portions under consideration and may include a physical engagement and/or a functional or operational connection.

Referring now to the drawings, there is illustrated in FIGS. 1 through 16 an interleaf, indicated generally at 20, according to the invention. The term “roof” may be understood to include an upper covering of a building. The term “interleaf” may be understood to include a device positioned generally between two or more shingles or other roof coverings on a roof. The term “shingle” may be understood to include a generally flat structure used to cover a roof. Shingles may be used in generally overlapping rows, or courses—or in any other suitable fashion.

Referring now to FIGS. 1 through 5, the interleaf 20 is shown positioned between an illustrated upper course 25 of shingles and an illustrated lower course 30 of shingles. Any of the interleafs shown in this application may be generally positioned as is the interleaf 20 shown in FIGS. 4 and 5. The upper course 25 includes a series of shingles positioned generally on top of the interleaf 20. The lower course 30 includes a series of shingles positioned generally below the interleaf 20. Each shingle shown includes a headlap portion 35 and a tab portion 40. It will be appreciated for the upper course 25 and lower course 30 shown, that the interleaf 20 is secured to the under surface of the tab portion 40 of the upper course 25 and the upper surface headlap portion 35 of the lower course 30. The interleaf 20 may be secured with any suitable adhesive, fastener or the like.

The interleaf may have any suitable length, width, and/or thickness. It will be appreciated that the illustrated interleaf 20 has a length L1 which is about the same as the sum of the length L2 of the tab portion 40 plus the length L3 of the headlap portion 35. In other words, for the interleaf 20 shown, L1=L2+L3. The length of the interleaf 20 may be lesser or greater than the length of a single shingle. It may be a multiple of the length of a single shingle or any suitable proportion or multiple thereof. The interleaf 20 shown has a thickness T1 at the exposed portion of the interleaf 20.

Referring to FIG. 1, it will be noted that the length of the interleaf 20 can vary as desired. FIG. 1 shows a plurality of interleafs 20a, b, c, d, e, f, g of varying lengths. For purposes of clarity in this application, the interleaf will be referred to with the single reference number 20.
