Installation Guide

Roof boards have lightly rounded edges on the face (assembly face down as the ceiling) and bevelings and
furrows on the back (assembly upwards as the roof underlayment).
The back side has usually wane on it. Again this is not a defect but a characteristic of the product and like
the floor boards, these have only one good side.
Safety first! Begin nailing the roof from front. Fix the first boards on both sides to align with the roof and
make sure that they sit flush with the edge of the purlins and that they do not exceed the centre line of the
ridge purlin at the middle. Nail all the boards both to the uppermost wall planks and all the purlins. Leave
aprx. 1/16”space between each roof board to allow them to expand and contract with moisture. Use the
centerline of the ridge purlin as a guide to keep the roof boards straight. Measure and trim the last roof
board to fit flush with the ends of the purlins (drawing 11). Trim cut the bottom line of the roof straight if
needed. Then fix the fascia boards according to drawing 12.
If the cabin includes roof boards of two different lengths, install the long one first starting from the front
and then alternate the short and long boards.
