Abstract
A shingle or other roof covering is provided, comprising a tab portion and a butt portion. The shingle surface is provided with a band zone, in which adhesive zones are applied. The band zones run the entire width of a shingle, and are preferably located either on the underside surface of the tab portions, or on the top surface of butt portions. The adhesive pattern is so that shingle lifting due to wind is resisted, but so that mois-ture can escape between ovelapped shingles when the adhesive secures them together.

It will also be understood that, while two bands 108, 112 of adhesive zones 111, 1I7,.are disclosed in the embodi-ment of Fig. 2, it .will be commonplace, and in many instances preferable, that only one such band of adhesive zones is utilized, either at the location of band 108, ar at the location of band 112, as desired.
It will also be apparent that various details of shingle construction, such as are embodied in Fig. 1, may also be util-ized with respect to Fig. 2, and that the same need not be dupli-cated herein.
With particular reference now to Fig. 3, it will be seen that another embodiment of a shingle 201 is disclosed, having a butt portion 202 and tab portions 203. The tab portions 203 are sepa-rated by slots 204,~as set forth above. It will also be under-stood that beneath an imaginary line 200 in the tab portions 203, there is provided a band 208 of a plurality of adhesive zones 211. The adhesive zones 211 likewise represent an alternative arrangement in which the aggregate dimension defined by the length "X "' for the plurality of adhesive zones 211 within the band portion "L "' are at least as great as, and preferably greater than the dimension "L "' between one end of one zone to :~ n : j ~..

With respect to the embodiments of Figs. 1 and 2, it will be seen that the spaces 26, 115 and 126 between adjacent adhesive zones are non-perpendicular to the horizontal band, and comprise a plurality of parallel sloped openings through the band. With respect to the embodiment of Fig. 3, such openings 226 are gener-ally sloped, given the elliptical configurations of the zones 211. It will be understood that such openings 26, 115, 126, 226, allow for escape of moisture from between overlying shingles of the type illustrated in Fig. 5 , rather than being trapped above the sealing zones indicated. Successive courses of shingles are thus able to breathe, but without allowing any substantial direct invasion of air, wind or the like in a direction perpendicular to the bands 8, 108, 112, 208, etc., and with respect to the embodi-ments of Figs. 2 and 3, without allowing any space for direct invasion of the bands 108, 208, by wind or the like, in a direc-tion perpendicular to that of the horizontal bands; namely, in a direction such as that indicated by the arrows 121 or 221.

parallelogram configurations 111 of Fig. 2. In some respects, the arrangement of Fig. 4 provides a more preferred embodiment, in that it allows for an even more acutely sloped spacing 326 between adjacent adhesive zones 311 than in Fig. 2, and additionally allows for an aggregate length of the individual zones "X'~'~ in Fig. 4 being even greater than the length "L " "
measured horizontally from one end of one zone to an opposite end of another zone in a band portion. Typical of such an acute angle "a" might. be 17°, as for example, where the height of the parallelogram is a unit of approximately one, and the length of a base line is a unit of approximately three. It will be understood that the illustration of Fig. 4 is not to scale, but is intended to be representative, only. It will likewise be apparent that various other angular relationships may be used, more greatly or in lesser amounts, acute, and even that other configurations other than parallelogram configurations may be used for the adhesive application.

In Fig. ~ it will be seen that nailing zones 24 are indicated to show how shingles are-secured to a roofing surface 45. As aforesaid, the strips 109 or the like which cover the adhesive zones of an adhesive band are removed before application, to allow adhesive in adhesive zones to secure tab and butt portions of a pair of shingles in two successive courses, to adhere to each other to resist wind lift-up and the like. -It will be apparent-from the, foregoing that while the pre-ferred form,of the invention is recited as being that of a shingle, that roof coverings of other types other than shingles may be utilized, such as-rolled roofing or the like, in which the same adhesive arrangements as are disclosed herein may be satis-factorily utilized. Furthermore, while shingles in accordance with this invention are recited as having a plurality of tab portions, in the preferred embodiment, it will be understood that a single tab portion may be utilized with a single butt portion, for a given shingle.

With respect to the embodiment of Fig. 3, such openings 226 are gener-ally sloped, given the elliptical configurations of the zones 211. It will be understood that such openings 26, 115, 126, 226, allow for escape of moisture from between overlying shingles of the type illustrated in Fig. 5 , rather than being trapped above the sealing zones indicated. Successive courses of shingles are thus able to breathe, but without allowing any substantial direct invasion of air, wind or the like in a direction perpendicular to the bands 8, 108, 112, 208, etc., and with respect to the embodi-ments of Figs. 2 and 3, without allowing any space for direct invasion of the bands 108, 208, by wind or the like, in a direc-tion perpendicular to that of the horizontal bands; namely, in a direction such as that indicated by the arrows 121 or 221.

parallelogram configurations 111 of Fig. 2. In some respects, the arrangement of Fig. 4 provides a more preferred embodiment, in that it allows for an even more acutely sloped spacing 326 between adjacent adhesive zones 311 than in Fig. 2, and additionally allows for an aggregate length of the individual zones "X'~'~ in Fig. 4 being even greater than the length "L " "
measured horizontally from one end of one zone to an opposite end of another zone in a band portion. Typical of such an acute angle "a" might. be 17°, as for example, where the height of the parallelogram is a unit of approximately one, and the length of a base line is a unit of approximately three. It will be understood that the illustration of Fig. 4 is not to scale, but is intended to be representative, only. It will likewise be apparent that various other angular relationships may be used, more greatly or in lesser amounts, acute, and even that other configurations other than parallelogram configurations may be used for the adhesive application.
