Installing the Roof Flashing
The roof flashing will seal the area between the center collar and the roof panels.
What You Should Know
Each roof flashing section overlaps and bolts together with the previously installed roof flashing section.
1. Install the first roof flashing section (A) onto the roof panel, and align the holes on the roof flashing
with the roof panel.
NOTE:
Flashing is not supposed to be attached to the center collar.
2. Install flange bolts (B) and flange nuts (C), securing the first roof flashing section (A) to the roof
panel ribs.
NOTE:
Only the first roof flashing section is installed using only six of the required flange bolts and
nuts. Any remaining unfilled holes will be filled when the last roof flashing section is installed.
