OSB ROOF
To install the OSB plates, it is essential that the rest of the structure is straight and level. Make sure that the
walls are level, that the gables are vertical and that the rest of the structure is straight. Check if there are any
intermediate failures to install before installing the OSB plates. To install the OSB plates, position them so
that they do not exceed the ridge purlin. To do this, start by positioning a plate on each side of the roof. Be
very careful to position them correctly so that they do not protrude from the ridge purge so as not to
interfere with the installation of the bituminous felt. To fix them, you will have to either screw them or nail
them, it all depends on the shelter chosen at the level of the intermediate and ridge purlins but also at the
level of the planks finishing the walls of the shelter. The screws are to be fixed vertically, the nails will be
planted, making sure that the point is inclined towards the center of the plate (see diagram in "Roof in
battens") to ensure good grip. Once the plates are fixed, position the bituminous felt. The load on the OSB
plates must not exceed 25 kg / m². The roof is designed to support light elements. In the event of snow, the
roof can support a maximum of 8 cm of fresh snow. Snow should be removed from the roof as it goes to
prevent it from melting and becoming heavier.
BITUMINOUS FELT
The roof of the shelter must be covered as soon as it has been assemled. Measure the lenght of the roof to
assess the lenght of the bituminous felt. The sheets of felt should be covered like fish scales, first fix the felts
close to the lower edge of the roof and reassemble so that the felts upstream cover the felts downstream.
Arrange the strips horizontally and overlap the felt when installing it. This provides better resistance and
tightness.Store the bituminous felt vertically in a dry place away from heat and cold.When laying, nail, screw
or glue close enough to the edges so that wind and rain cannot easily infiltrate. At a minimum, it is mandatory
to check the waterproofness of the roof every year.
TREATMENT:
- Before assembly we recommend to treat the beams twice all four sides of the board with an oil-based
protective product-to protect the wood from fungus, blackening, and insects.
- Once the assembly is completed, we recommend that you treat the garden shed with selected protective
treatments or paint it. Untreated wood will turn gray / black if left as it is for a while, or even blue, and traces
of moisture may appear. By regularly applying a new finishing layer the life of your shed shall be lengthened.
This should be repeated every 3 years.
- We strongly recommend that you also treat doors and windows with a colorless wood impregnating agent,
indoors and outdoors! Otherwise the doors and windows could bend.
- To paint, use high quality tools and paint. Please follow the manufacturer's operating and safety instructions
and the application manual. Never paint a surface in very sunny or rainy weather. Consult a specialist for
paints suitable for untreated softwood and please follow their instructions.
The lifespan of your garden shed, as with many natural products, is subject to the frequency of the protective
treatment.
FOUNDATION:
Before assembling the shelter, make sure that the foundations are flat, level and fixed to the ground. You can
pour a concrete screed or use joists for example (not shown).
