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).
