InsTallaTIon of fInal Panel
While backlapping the last roof panel (to match panel coverage with the building length) is routinely
done, this installation method can compromise the integrity of the roof by trapping moisture
between the panels . This moisture could, in time, create an environment conducive to rust and
metal failure .
Manufacturer recommends field cutting the final panel lengthwise to create
the desired panel width necessary to finish off the building.
The cut edge of the panel
should always be installed on the outside edge, not the lap edge . The “narrow” panel should be
handled with care, and foot traffic avoided until the final panel is completely installed .
