MK2 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 supported 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 neces-
sary to temporarily 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 correct-
ly then rivet together, 400mm down from the
centre on both sides. Fit remaining Roof
Sheets.
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 Roof-
ing 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.
