Step 2:
Position first Roof Sheet centrally over Ridge

Note:
Condensation can form on the under side of shed roof. If building paper is required, fit now. Building paper will need to be sup-
ported by netting or roofing twine.
Step 1:
Check that the diagonal measurements of the shed are the same. If building on unlevel ground it may be necessary to tempo-
rarily brace the shed with pieces of timber from the packaging.
Step 3:
Starting from the left hand end, centralize Roof on
Ridge Beam. Ensure Roof is tight against end Wall
Sheets, predrill then nail one 50mm Clout through
Rib into the Ridge Beam. At the back, line up Ribs on
the Roof Sheet with the Ribs on Wall Sheet. Using
one 50mm Clout, nail through Rib into Back Top
Plate. Repeat at the front.
Note The 6 x 50mm Clouts on end ribs are covered by the
Barge Flashings.
Step 4:
Centralize Roof at the other end and nail through
Rib into the Ridge Beam and Top Plates, using
50mm Clouts. Ensure Ridge Beam is straight, then
Screw one 50mm Roofing Screw into Ridge Beam
through each Rib on overlap (one screw per sheet).
At the back, set up a String Line in centre of Top
Plate. Ensure Top Plate is straight and screw, using
one 50mm Roofing Screw per Rib. Repeat at the
front.
