Assembly of verge boards
Screw the verge boards to the eaves boards so that the
underside is flush with the lower edge. This means that
they are approx. 2 cm above the roof covers plates
How to cover and protect your roof
The roof should be covered with asphalt, tar paper,
shindles, or a high quality PVS or ABS trapezoid roof
covering.
A provisional roof felt-cover is part of the delivery, but this
is NOT a substitute for a proper roof covering. You can see
this as temporary protection (max. three months) until
bitumen sheeting, trapezoid cover sheets or the like MUST
come on top of it.
If available: Roof panels / trapezoidal panels made of PVC
and with ridge cover (holes must be pre-drilled!) must
fastened with flat headed screws.
Make sure to seal the trapezoidal sheets on the downward-
facing side with silicone or SikaFlex.

The Roof
Assembly of the roof boards
Please note:
Rafters, edges, eaves and gable
boards must be nicely parallel! No slits
or open seams!
Always start attaching the roof plates
in the middle and then work outwards!
Due to the construction of roof frame,
there should be no seams, or slits in
the ridge area!
Check that there is roof overhang
before you start fixing everything in
earnest!
