Take two sections of roof batten.
Tile roof battens spacing.
The slate or tile manufacturer or supplier will specify the spacing of the battens up the roof for the particular type of covering this spacing is referred to as the gauge the gauge may depend upon the pitch of the roof and the amount of exposure.
Because battens support the tiles the spacing is determined by the size of the tiles and the length of the roof to be covered.
Roofing battens or battening also called roofing lath are used to provide the fixing point for roofing materials such as shingles or tiles.
Their spacing is determined by the size of the tiles and the height and pitch of the roof to be covered.
To ensure this the battens should be at least 1 2m long.
Step 1 rest a sample tile on the roof so the bottom edge overhangs the fascia and guttering by the distance recommended by the tile manufacturer taking into account any local ordinances that apply to your building.
Here are some guidelines to bear in mind.
Battens should be fixed to rafters set at centres not more than 600mm apart.
According to bs 5534 the appropriate batten size will depend on the span of the rafters and the roof covering.
Battens should be fixed to rafters set at centres not more than 600 mm apart and should span at least 3 rafters.
Shingles and tiles are affixed using the battens as spacing.
Spacing the battens the next thing to do is to work out the spacing for the battens up the roof.
Not more than one in four battens should be joined over one truss for gauges over 200mm.
Place these on the roof one above the other.
The gauge is in fact the same as the margin which is the length of the tile exposed.
The supplier of the tiles should recommend the spacing up the roof between the battens known as the gauge this usually varies according to the size of the tiles the pitch of the roof and the degree of exposure.
The spacing of the battens depend on the type of roofing material and are applied horizontally.
Battens are not always used in a roofing system.
