Abstract
A multiple-layer laminated shingle and a method of making the shingle are provided, in which at least one thermal set adhesive of high temperature resistance is applied for securing the shingle layers together, to reduce reliance on a roofer having to fasten (via nails, staples or other fasteners) through a narrow headlap zone of a posterior shingle layer in order to secure the posterior shingle layer to a roof; such that a vertically wide portion of the headlap area of the anterior shingle layer is presented to the roofer as a nailing zone.
