 21' Diameter Gamma Roof Assembly Instructions

Attaching the Roof Panels

Roof panels overlap the previous roof panel, giving protection from outside elements. Rafters and roof 
panel support clips will support to hold the roof panels.

Before You Begin

Ensure all roof rafter assemblies and purlins are installed and properly tightened. Pre-determine the 
manway access location. Make sure roof panel support clips are attached on the purlins before installing 
the roof panels (A).

What You Should Know

For adjustment purposes, roof panels (A) are installed to each rafter first, causing exposed gaps (B) 
between each roof panel (A) group. 

(See Figure 4P.)

 After all roof panels are installed, ensure that all 

installed hardware (flange bolts with sealing washers and flange nuts) are tightened to secure the 
roof panels.

When installing the roof panels (A), take into consideration placing the manway for ease of access to and 
from the sidewall and roof ladders.
