MK3A ROOF
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 2:
Position first Roof Sheet centrally over Ridge Beam
on the right hand end of shed with the LIP on the left
hand side. (For sheds with a Clear Roof Panel, go to
the next page). Position the next Roof Sheet. Ensure
it overlaps correctly then rivet together, 100mm and
600mm down from the centre on both sides. Fit re-
maining Roof Sheet.
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. En-
sure Top Plate is straight and screw, using one 50mm
Roofing Screw per Rib. Repeat at the front.
