Abstract:
1. A method of securing an installed metal roof deck formed by a plurality of rectangular, overlapping, corrugated panels covered with at least one layer of insulation or sealer and supported from below by a plurality of parallel beams comprising the steps of: identifying a first location for a first fastener, wherein the first location occurs where a first beam meets a first valley in the corrugated panels; drilling a first access hole through the at least one layer of insulation or sealer at the first location, wherein the first access hole does not extend through the corrugated panels; positioning a first self-tapping screw through the first access hole and driving the first self-tapping screw through the corrugated panels and into the first beam; identifying a second location for a second fastener, wherein the second location occurs where the first beam meets a second valley in the corrugated panels; drilling a second access hole through the at least one layer of insulation or sealer at the second location, wherein the second access hole does not extend through the corrugated panels; positioning a second self-tapping screw through the second access hole and driving the second self-tapping screw through the corrugated panels and into the first beam; positioning a template that extends from the first self-tapping screw to the second self-tapping screw, wherein the template includes regular marks to identify intersections between valleys in the corrugated panels and the first beam; drilling additional access holes through the at least one layer of insulation or sealer at locations aligned with the regular marks on the template, wherein the additional pilot holes do not extend through the corrugated panels; and positioning additional self-tapping screws through each of the additional access holes and driving the additional self-tapping screws through the corrugated panels and into the first beam.
