Installation manual
Apex
In most cases, the apex is supplied in one piece (attention: in some house options, the apex can comprise
several parts! In this case, these parts will have to be screwed together prior to other actions). Having installed
the last wall logs, place the apex on the front and back walls and attach them with screws.
The apexes have indents for the rafters. The rafters also have the corresponding indents, ensuring that the
roof is placed firmly and in the right place.
Now place the rafters

apexes.
Make sure that the upper wall log,
apexes and rafters are level. Having
fitted the rafters, screw them onto
the apex from above.
ATTENTION: If the wall logs are not properly pressed on top of one another without gaps, the upper wall log
may not be on the same level with the apexes. In this case you should tap the wall logs downwards as
necessary or plane the apex or sidewall log somewhat lower.
Roof
Before installing the roof boards, make sure that the house is completely level. Use the water-level to
check all walls.
ATTENTION: When placing the roof, use a stable ladder. Do not step on the roof as the structure is
suitable to sustain only an even load (snow, wind, etc.), and not a point load!
Begin the installation of the roof boards from the front edge of the roof. Tap the boards lightly and
attach them from above and below with nails to the rafters and upper wall log.
ATTENTION: Do not press the roof boards together too densely and you will avoid moisture-causing
bulging! Leave an interval of about 1 mm between the boards to allow for swelling.

During the whole process of installing the roof boards, make sure that their crest rafters coincide
and the eave sides of the boards extend at a uniform distance. Verify this with a rope or the lateral
eave lath that you may install for verification purposes.

The roof boards must be even with the rafter ends in front and behind. If necessary, saw both last
roof boards so narrow that they are even with the rafter ends.
