The Nature of Wood
The wood provided for your garden building is softwood which has been kiln dried and is pressure treated for
protection against fungal decay and insect infestation. Wood is a natural product which may have knots, knot holes,
imperfections, cracks and warping.
Due to the inherent properties of wood we make no guarantees with regards to the above, nor will replace any
lengths of timber for any of the following reasons:
•Any timber that contains knots where they do not influence the structural stability of the product.
•Cosmetic appearances - colour variations e.g. caused by the structure or age of the product.
•Timber that has shakes, cracks or gaps that do not influence the structural strength of the product.
•Any timber that has been covered or buried underground.
•Twisted timber that can be installed.
•Queries arising from a neglectful manner of construction be in the foundation or erection of the product.
•Queries due to modifications by the owner causing timber to deform.
Any valid queries will be satisfied by the exchange or replacement of the defective parts only.
Your Gazebo has been designed with the self build in mind. However, it is important that the assembly
instructions are followed carefully.
Precautions:
•Always use working gloves.
•It is essential to have an assistant.
•All screw holes need to be pre-drilled using a 3mm drill bit (not provided) to avoid timber splitting.
The Gazebo is pressure treated so you will not need to treat it immediately or apply a preservative.
Pressure treatment does not mean that the timbers are waterproof, so you may wish to apply water repellent.
Water repellent can also be applied to timbers treated with a preservative.
Colour Transfer
This product has been pressure treated with wood preservative and a brown colour additive. Consideration should
be given to the propensity of the material to stain light colour adjacent surfaces, such as paving flags, render or
coated timber surfaces. We recommend contact between the timber and these surfaces is limited, and careful
consideration to storing the product prior to assembly should been taken in order to prevent such discolouration.

•Start to fix the Roof Boards by positioning the longest board flush to the ends of Rafter and 22mm to the
centre. See diagram below.
•Use 1x Ring Shank Nail for every Rafter it touches.
•Repeat the above steps for every roof section.
Note: The wall panels have been hidden from view for illustration purposes
Leave a 2mm gap between each roof board
•Using the same principle from previous step continue to place roof boards rising up
to the gazebo apex (place roof boards in levels rather than sections in order to keep
roof boards square.)
•Leave a gap of approximately 2mm between each Roof Board using a 2mm spacer
(not provided).
•Work your way up to the apex of the roof.

Plastic Waterproof Membrane:
•Fully cover the roof with the plastic waterproof membrane leaving a minimum of 30mm overhang.
•Use a staple gun or tacks to secure the membrane to the roof boards.
Felt:
•Starting at the lowest edge of the roof, lay the felt horizontally across the roof boards.
•Make sure that the lowest edge of the felt overhangs the eaves edge of the roof by approximately 40-50mm, and by
approximately 50mm on the front and back edges.
•Nail at approximately 200mm intervals.
•Overlap by 200mm if you need to connect two rows of felt.
•Continue laying the next layers of felt and nail into the roof boards at 200mm intervals horizontally and with 300mm
intervals vertically.
•Overlap the layers by 200mm and we recommend you seal any joints using the optional felt lap adhesive.
•Repeat this process on the opposite side of the roof.
IMPORTANT
•When the felt has reached the ridge, fold over a length of felt to cover both sides of the upper layers of felt by 200mm
or more, seal the joints and nail together.
•Make sure to nail the felt on both sides of the ridge.
•Diagrams used for visualisation purposes.
•Quantity of layers of the felt may vary.

•Felt lap Adhesive is an optional extra.
Step 1: Starting on the lowest edge of the roof, place a row of shingles over the top of the roof membrane, place slots
running upwards with the black edge of the shingle overhanging the roof by 15-20mm and nail along the bottom edge
of the tile using 4 nails provided. Carefully trim off any excess at the end of the row and keep any full 'tabs'.

Continue to lay the shingles in a row off-set and by overlapping each row until you have reached the ridge. (Use the
off cuts to fill in the spaces at the beginning and end of the rows).
Cut the shingles into three tabs and taper the adhesive edge. Rotate shingles to run parallel with the ridge, gently
bend over the ridge and secure in position with nails. Once all ridge shingles meet at the tip of the roof overlap
shingles and secure into place with nails.

Important: Adhesive layer (Bitumen) on the back of the shingles will adhese the shingles together in warm
sunlight.
