Assembly Instructions
INSTALLING THE FIRST PANELS ON A 14’, 20’, OR 26’ WIDE CARPORT 
When you install sheet metal panels on a 14’, 20’ and 26’ wide carport, the first course of panels down the peak will be 
positioned to one side of the roof and the first panels on the other side of the roof will overlap these panels 10” or to the 
second major rib. See illustration below. 
If you have a 14’, 20’ or 26’ wide carport, you should have marked all of the peaks on the frame sections 3 5/8” from one 
end. This mark will be the guide for the under lap edge of the first course of roof panels. If you did not mark the peaks, 
mark them now. See page 9. 
Install the first panel as shown below with the proper overhang (11” ) On Center frames). Do not install screws above the 
lower edge ribs at this time . Do not install screws into the third frame section at this time. 
Run a bead of butyl caulk tape at the end of the panel 1” from the end as shown below. Let a little caulk extend slightly 
over each edge.

In order to seal panels properly and prevent leaking, each course of panels running from front to back on your carport 
must be completely sealed with butyl caulk tape or clear butyl caulk from a caulk gun. The ideal assembly would have full 
length roof panels. For purposes of shipping and handling, this is not possible. Several lengths of panels are provided 
and these lengths must be sealed together to extend the length of your carport. 
You may have a carport that is longer or has more than two panels down the length of the carport. Each additional panel 
must be sealed to the previous panel, as you will seal panel two to panel one. See next page for Panel 2 installation.
