An improved cinch strap and backup plate, used to form an enlap joint between two overlapping roofing panels, is disclosed. The backup plate is provided with horizontally extending shoulders which protrude outwardly from each end of the plate. One shoulder provides support for the endlap joint during its assembly, while the other shoulder provides support for later installed endlap joints. The cinch strap is configured to conform to the contour of the roofing panels. The cinch strap is provided with spines which provide structural support, and drainage channels which help to clear moisture from the roof. The cinch strap is configured so as to engage other, aligned cinch straps in a head-to-tail arrangement. The improved cinch strap and backup plate provide a structurally stronger, weatherproof endlap joint. |
