A roofing shingle (20) comprises a web (22) of roofing material configured with a first series of sealant material sites (60) and a second series of sealant material sites (62) provided on the roofing shingle (20). The web (22) of roofing material is configured with a length dimension (L) and a width dimension (W). The sealant material sites 60 of the first series are provided along a first axis (66) which is essentially parallel to the length dimension of the web. The sealant material sites (60) of the first series are discontinuous along the first axis (66) and separated from one another along the first axis by a first interval (70). The sealant material sites of the second series (62) are provided along a second axis (68) which is essentially parallel to the length dimension of the web and spaced apart from the first axis (66) with respect to the width dimension. The sealant material sites (62) of the second series are discontinuous along the second axis (68) and are separated from one another along the second axis (68) by a second interval (72), the second interval (72) being different than the first interval (70).
