The maximum headlap overlap dimension is beneath the subsequently installed shingle laterally proximate the openings in the buttlap portion of the subsequently installed shingle. A method for making the shingle is disclosed comprising cutting a sheet of roofing material longitudinally along non-straight lines wherein at least a portion of each formed shingle has a width of about twelve inches.
