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 in the 
corresponding indents in the 
apexes. 
Make sure that the upper wall log, 
apexes and rafters are level. Having 
fitted the rafters, screw them onto 
the apex from above. 
 Installation of rafters: 
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.
