TL;DR
Nail overdrive is the fastening defect in which a pneumatic nailer sinks a nail head through a shingle's surface mat instead of seating it flush, cutting the shingle and destroying its hold. Overdriven fasteners void wind warranties and show up later as creeping or blown-off shingles, and they commonly trace to excessive compressor pressure or careless gun depth settings.
What it means
Nail overdrive is the fastening defect in which a pneumatic nailer sinks a nail head through a shingle's surface mat instead of seating it flush, cutting the shingle and destroying its hold. Overdriven fasteners void wind warranties and show up later as creeping or blown-off shingles, and they commonly trace to excessive compressor pressure or careless gun depth settings. Manufacturer specs and roofing inspections call for heads flush with the surface — neither raised nor buried.
