Chapter 7: Roof Assembly
Attaching the Roof Panels
Roof panels overlap the previous roof panel, giving protection from outside elements.
Before You Begin
Ensure all A-frame roof rafter assemblies are installed, and ensure all intermediate purlins are installed
and properly tightened. Predetermine the manway access location.
What You Should Know
For adjustment purposes, roof panels will be installed to each rafter first, causing exposed gaps between
each roof panel group (see figure below). After all roof panels are installed, ensure that all installed hard-
ware (flange bolts with sealing washers and flange nuts) are tightened to secure the roof panels.
