ABSTRACT:
A roofing material fastener comprises a shank having a length dimension and a point. The shank is adapted to enable it to be driven through at least a first course of roofing material and into a roof deck. A fastener head is positioned in a region of the shank distal from the point. A spike protrusion projects from the distal region of the shank to a terminus. The length of the spike protrusion is less than one half the length of the shank, measured from the point to the fastener head. The spike protrusion is adapted to penetrate a depth less than the full depth of a second course of roofing material installed above the first course. The spike protrusion is shaped to inhibit sawing through the second course of roofing material by the spike protrusion.
