Take two sections of roof batten.
Tile roof battens spacing.
For example 25x50mm battens should be used for single lap modern roof tiles when laid on rafters with a 600mm span.
The spacing of the battens depend on the type of roofing material and are applied horizontally.
Their spacing is determined by the size of the tiles and the height and pitch of the roof to be covered.
According to bs 5534 the appropriate batten size will depend on the span of the rafters and the roof covering.
Battens are not always used in a roofing system.
Because battens support the tiles the spacing is determined by the size of the tiles and the length of the roof to be covered.
Place these on the roof one above the other.
It is also important aesthetically so that the tiles on the finished roof are equally spaced.
Battens should be fixed to rafters set at centres not more than 600 mm apart and should span at least 3 rafters.
Spacing the battens the next thing to do is to work out the spacing for the battens up the roof.
Roofing battens or laths are strips of timber which are nailed into lines along the roof trusses of a house from which the roof tiles are hung.
Shingles and tiles are affixed using the battens as spacing.
To ensure this the battens should be at least 1 2m long.
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.
Battens should be fixed to rafters set at centres not more than 600mm apart.
Here are some guidelines to bear in mind.
Not more than one in four battens should be joined over one truss for gauges over 200mm.
The gauge is in fact the same as the margin which is the length of the tile exposed.
