CGI Roof Sheets
Position the first corrugated roof sheet so it is level with the front or
back panel (depending on where you start). Allow an even overlap
on both sides of the side panels. Rivet the sheet (in the valley of the
corrugations) to the top of one of the side panels. Weatherproof the
rivets with silicone.
When one end of the corrugated roof sheet is secured, push down
on the other end to create a small arc over the ridge beam. Ensuring
the sheet is flush with the front wall, rivet the sheet to the top of
the remaining side panel (Figure 6).
Barge Flashing
When all the roof sheets are positioned, fix the barge flashings to
the roof sheets (Figure 8). These overlap each other to provide a
firm seal.

Ridge Beam
On the top edge of the front and back panels, measure the centre
of the shed and mark it so that the ridge beam can be centered
correctly (Figure 4). After drilling pilot holes, fix the ridge beam to
the top of the wall panel with the rivets provided (Figure 5).

Ensure the corners of the panels are lapped correctly. Drill four
evenly spaced holes through both the overlaps (Figure 2) and
secure with rivets (Figure 3). Use the same method to attach the
other side panel and then the front panel of the shed.
To make sure the shed is square, measure the diagonals. They
should be equal lengths.

Walls
Carefully lay all four panels on the ground in their correct positions
(Figure 1). With the aid of another person, lift the back panel and
one of the two adjacent side panels into the vertical position.

The corrugated sheets should be laid directly from the pack, side by
side, with a one and a half corrugation overlap. The sheets should
be laid into the prevailing wind (Figure 7).
