of the full size shingle 11 and just slightly removed from the minor edges 15 an intermediate pair of adhesive bands 27 are located at the one third and two third points as measured along the major edges 13 of the full size shingle 11 one edge of the intermediate pair of adhesive bands 27 is at the one third and two thirds point line with each of the intermediate adhesive bands 27 within the one third part of the full size shingle closest to the nearest minor edge 15 a middle adhesive band 29 is located substantially along the centerline between the two minor edges 15 referring now to fig2 the smaller or half size shingle 30 is shown the half size shingle 30 like the full size shingle 11 includes the upper portion 19 and the lower portion 21 this shingle also has a pair of major edges 31 and a pair of minor edges 33 the major edges 31 are approximately one and one half times the length of the minor edges 33 the minor edges 33 of the half size shingle 30 are substantially the same length as the minor edges 15 of the full size shingle 11 with the half size shingle 30 only one pair of adhesive bands 35 are on the shingle 30 again each of the adhesive bands 35 should be at least one quarter inch in width as with the larger or full size shinge 11 however with the half size shingle 30 shown in fig2 each of the adhesive bands 35 is substantially as long.
