5.6 Installing the top flashing
Mounting steps:
• Install additional roof battens 30 mm below and
280 mm above the upper end of the corrugated metal
sheet area (measured form the centre of the battens).
The second roof batten should stick out above the top
flashing to allow the fixing clip.
• Position the left-hand and right-hand corner flashing
with the respective two outer corrugations and the
flat part overlapping the lateral flashing, and push
them downwards as far as they will go. (Alternatively, by
use of a rubber hammer, about 150 mm of the top
flashing respectively (see area marked in grey above).
The flattened sheets can then be used in place of the
corner flashings).
• Continue positioning the top flashings, taking care to
align them properly and to have them overlap
each other by at least 80 mm (= two high points of the
corrugation). Fix each overlap with an adapter and 2
screws 6.5 x 65 mm (if in the right position) or with a
calotte and screw 4.5 x 45 mm.
• Work the upstand of the flashings with tinsmith tools to
ensure a clean overlap.
• Fix the upstand to the underlying batten at least every
500 mm, using fixing clips and screws 4.5 x 45 mm.
• Complete the fixation of the top flashings by fixing the
corrugated part at least every 500 mm, using adapters
and/or calottes and the according screws.
