Abstract

A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line. Additionally, the person applying shingles to a roof is directed where to apply the fasteners, so that a greater number of fasteners secure a given shingle to the roof.

Claims

1. A wind-resistant shingle having front and rear surfaces comprising a web coated with a solidified coating material and having a layer of granules on a surface of the coating material, with the shingle having a butt portion and a tab portion, each of which portions extend longitudinally of the shingle;

with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end, and with the lower end of the butt portion merging with the upper end of the tab portion;

with a pair of generally horizontal, visually distinct, vertically spaced-apart lines extending longitudinally of the front surface of the shingle in the lower end of the butt portion of the shingle, on the layer of granules, adjacent the upper end of the tab portion of the shingle;

with at least the lowermost one of the vertically spaced-apart lines comprising a line of sealant; and

with said visually distinct vertically spaced-apart lines defining therebetween a generally horizontal, longitudinally-extending fastener area for visually directing a predetermined location for fastener placement in applying shingles to a roof.

2. The shingle of claim 1, wherein both of said pair of vertically spaced-apart lines comprise lines of sealant.

3. The shingle of claim 1, wherein indicia means on the shingle define a generally horizontal longitudinally-extending, visually distinct line of fastener application, located in said fastener area.

4. The shingle of claim 3, wherein said line of fastener application is visually discontinuous.

5. The shingle of claim 4, wherein the shingle is a multi-tab shingle having generally vertically disposed, horizontally spaced-apart slots in the tab portion and wherein said discontinuous line of fastener application comprises fastener location spots above the upper ends of said slots.

6. The shingle of any one of claims 1-5, with said at least one line of sealant being discontinuous.

7. The shingle of any one of claims 1-5, wherein the shingle has an overall height in the vertical direction of essentially 18 inches, with the butt portion having an overall height in the vertical direction of essentially 10 inches and the tab portion having an overall height in the vertical direction of essentially 8 inches and wherein the fastener area has a sealant-free height in the vertical direction within the range of 1/2 inch to 1 and 1/16 inches.

8. The shingle of any one of claims 1-5, wherein the fastener area is at a vertical height in the butt portion of the shingle to comprise means whereby, when shingles are laid up in courses on a roof, with tab portions of shingles of an overlying course overlying butt portions of shingles of a next-underlying course, leaving only tab portions of shingles exposed, fasteners applied in the fastener area when fastening shingles to a roof will pass through the upper ends of the butt portions of shingles of the next-underlying course.

9. The shingle of claim 8, wherein the shingle has an overall height in the vertical direction of essentially 18 inches, with the butt portion having an overall height in the vertical direction of essentially 10 inches and the tab portion having an overall height in the vertical direction of essentially 8 inches and wherein the fastener area has a sealant-free height in the vertical direction within the range of 1/2 inch to 1 and 1/16 inches.

10. The shingle of claim 4, wherein the shingle is of the single-tab type, not having slots in its tab portion, and wherein said discontinuous line of fastener application comprises fastener location spots in the lower end of the butt portion of the shingle.

11. A method of applying shingles to a roof to resist wind-induced stripping of shingles from the roof, comprising:

(a) providing an underlying course of shingles, each having a web coated with a solidified coating material and having a layer of granules on a surface of the coating material, with each shingle having;

a butt portion and a tab portion, each of which portions extend longitudinally of the shingle;

with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end, and with the lower end of the butt portion merging with the upper end of the tab portion;

with a pair of generally horizontal, visually distinct, vertically spaced-apart lines extending longitudinally of the shingle in the lower end of the butt portion of the shingle, on the layer of granules, adjacent the upper end of the tab portion of the shingle;

with at least the lowermost one of the vertically spaced-apart lines comprising a line of sealant; and

with said vertically spaced-apart lines defining therebetween a generally horizontal, longitudinally-extending fastener area for directing a predetermined location for fastener placement in applying shingles to a roof;

(b) fastening the shingles of the underlying course to the roof by applying fasteners through the fastener areas of the underlying courses of shingles into the roof;

(c) providing an overlying course of shingles, each having a web coated with a solidified coating material and having a layer of granules on a surface of the coating material, with each shingle having;

a butt portion and a tab portion, each of which portions extend longitudinally of the shingle;

with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end, and with the lower end of the butt portion merging with the upper end of the tab portion;

with a pair of generally horizontal, visually distinct, vertically spaced-apart lines extending longitudinally of the shingle in the lower end of the butt portion of the shingle, on the layer of granules, adjacent the upper end of the tab portion of the shingle;

with at least the lowermost one of the vertically spaced-apart lines comprising a line of sealant; and

with said vertically spaced-apart lines defining therebetween a generally horizontal, longitudinally-extending fastener area for directing a predetermined location for fastener placement in applying shingles to a roof;

(d) applying shingles in the overlying course to the roof with tab portions of shingles of an overlying course overlying butt portions of shingles of a next-underlying course, leaving tab portions of shingles exposed; and

(e) fastening the shingles of the overlying course to the roof by applying fasteners

(i) through the fastener areas of the overlying course of shingles; and

(ii) through upper ends of butt portions of shingles of the next-underlying course of shingles.

12. The method of claim 11, wherein both of said pair of vertically spaced-apart lines comprise lines of sealant on each shingle.

13. The method of claim 11, wherein indicia on the shingles define generally horizontal, longitudinally-extending, visually distinct lines of fastener application, located in said fastener areas, and where the fasteners are applied through the lines of fastener application.

14. The method of any one of claims 11-13, wherein the lines of fastener application are visually discontinuous.

15. The method of claim 13, wherein the shingles are multi-tabbed shingles having generally vertically disposed, horizontally spaced-apart slots in the tab portions and wherein said discontinuous lines of fastener application comprise fastener location spots above the upper ends of said slots, and wherein the fasteners are applied through the fastener spots.

16. The method of claim 14, wherein the shingles are of the single-tab type, not having slots therein and wherein said discontinuous line of fastener application comprises fastener location spots in the lower ends of butt portion of the shingle, and wherein the fasteners are applied through the fastener spots.
