Abstract
A roofing shingle for enhanced wind/rain durability embodies two transverse lines of adhesion. A first discontinuous line of adhesive joins the butt edge of an overlying shingle to the underlying shingle. Secondly, a band of sealant adjacent the top edge of an underlying shingle seals against an overlying shingle to prevent penetration by wind driven rain to the roof deck. A reduced headlap is thereby permitted, thereby either reducing shingle size or extending shingle coverage. Exposed portions of the sealant band improve the erosion resistance of underlying shingles.

wherein the width of the shingle is more than twice said cut-out length;
and wherein the face of the shingle has an adhesive strip and a sealant band adapted to adhere to an overlapping shingle, the strip being discontinuous and aligned on the covered portion parallel to the butt edge above the apex of said cut-out, and sealant band is continuous being positioned at an imaginary fine parallel to and twice the cut-out length from the butt edge;
wherein the width of the shingle is more than twice said cut-out length;
and wherein the face of the shingle has an adhesive strip and a sealant band adapted to adhere to an overlapping shingle, the strip being discontinuous and aligned on the covered portion parallel to the butt edge above the apex of said cut-out, and sealant band is continuous being positioned at an imaginary fine parallel to and twice the cut-out length from the butt edge;
10. The shingle of claim 9 wherein the width of the shingle is twice the cut-out length, plus a head-lap distance.
11. The shingle of claim 10 wherein the headlap distance ranges from 1/4"
to 2".
to 2".
12. The shingle of claim 10 wherein the headlap distance ranges from 1/2"
to 3/4".
to 3/4".
13. The shingle of any one of claims 9 to 12 wherein at least a portion of the sealant band is offset toward the butt edge of the shingle from the imaginary line.
14 14. The shingle of any one of claims 9 to 13 wherein the sealant band brackets the imaginary line.
15. The shingle of any one of claims 9 to 13 wherein the sealant band is parallel to but offset from the upper edge of the shingle.
16. The shingle of any one of claims 9 to 15 wherein the width of the sealant band is in the range of 1/4" to 2".
17. The shingle of any one of claims 9 to 16 wherein the width of the second adhesive strip is in the range of 1/2" to 1 ".
18. The shingle of any one of claims 1 to17 wherein the sealant is an erosion resistant composition.
19. The shingle of any one of claims 1 to 18 wherein the sealant is a suitable acrylic, butyl, bitumenous or modified bitumenous composition.
20. The shingle of any one of claims 1 to 19 wherein the side edges of the shingle have complimentary spacing indicators.
21. The shingle of claim 20 wherein spacing indicators are notches or slits.
22. The shingle of claim 20 wherein the spacing indicators are offset stepped rectilinear notches.
23. The shingle of claim 22 wherein each side edge has two successively inset rectilinear notches, the first notch located a distance equal to said cut-out length from the butt edge, and the second notch inset further than the first notch at a selected distance above the first notch.
24. The shingle of claim 21 wherein each side edge has two spacing indicators, the first indicator being a notch located a distance equal to said cut-out length from the butt edge, and the second indicator being a slit positioned at a selected distance from the first indicator.
25. The shingle of claim 23 or claim 24 wherein the selected distance is in the range of 1/2" to 1 1/2".
26.
