ROOF ASSEMBLY CONT...
STEP 3:
• Ensure shed is sitting level and square.
• Beginning from the left hand end (looking from front)
centralise the Roof sheets on the Ridge Beam.
• Ensure that the Roof is tight against the Gable Wall Sheets. Screw 1 x 50mm Roofing screw through the 1st pan into
the Ridge Beam. (a - fig.2).
• At the back left hand corner, (from front) line up the ribs on the Roof Sheet with the ribs on the Wall Sheet then using
1 x 50mm Clout, predrill and nail Roof Sheet through the rib into the Top Plate. (b– fig.2.)Repeat at the front left hand
STEP 4:
• Centralise the Roof at the other end (R/H end) with the Ridge Beam.
• Using 1 x 50mm Roofing Screw, fix roof sheet though the pan, to the other end of
Ridge Beam. (d–fig.2).
• Using 2 x 50mm Clouts fix sheet though rib to front & back Top Plates. (e–fig.2).
• Ensure that the Ridge Beam is straight, screw roof sheets to ridge beam beside
each overlap, through the pan using 5 x 50mm Roofing screws.
• Ensure the Front and Back Top Plates are straight. Screw the roof sheets to the
front & back Top Plates, through the ribs, using 1 x Roofing Screw per rib. (fig.1).
STEP 5:
• Place barge flashings on roof at end of
shed ensuring the diagonal trimmed end
is facing out. (See diagram on pg. 5)
• Rivet the Barge Flashings to the roof
and the side wall, using four rivets on top
of barge and four into the side (fig.3).
STEP 6:
• Rivet the 2 Ridge Caps together using 4
x rivets, so total flashing is 3.050m long.
Rivet the Ridge Cap to the centre of the
roof using 10 x rivets as shown (fig.2).
STEP 7:
• Place spouting in position and rivet to
Barge Flashings at each end and rivet to
roof sheets (1 rivet per 1 sheet) (fig.4).
IMPORTANT
Use 50mm Clouts only on ribs covered by flashings,
shown in fig.2. Predrill holes using a 3.5mm drill bit.
Use Roofing Screws on all other ribs and pans.
Ensuring screws are not overtightened as this can dam-
age the seals and cause the shed to leak.
