The reason our product is dyed blue is to distinguish it as meeting the necessary standard: it's a colour commonly used by Nordic and Baltic suppliers. But it's the BS5534 grading stamp, not the colour, that's important.”
In most cases, irrespective of rafter spacings, 50 x 25mm battens should be used for our standard preholed fibre cement slates. Where BS 5534 suggests 38 x 25mm battens are acceptable, the slates should only be laid with 100 or 110mm lap.
The original idea behind putting a dye into the battens' preservative treatment was to make “graded” battens stand out from the usual, “ungraded” ones (which usually look a bit green in colour, on account of the type of preservative used) and for that reason, the colouring process was originally very successful – with

Roof battensThey maintain the roof covering in straight, consistent rows, and provide a strong anchor for the nails or clips used to secure the tiles or slates. They must be capable of carrying both the 'dead' loads and 'live' loads, and are typically timber, but can also be plastic which does not decay as easily.
Counter battens are wooden strips that are installed vertically over pitched roofs to which horizontal tiling battens are attached. They are used to allow rainwater to pass off the tiles and away from your roof.
The quick answer is YES. Roof battens no matter how you look at them are a structural element of any roof.
Battening a wall for plasterboard or dry lining is a great way of providing a little warmth and fighting condensation in a cold building. However, without adequate ventilation behind the board, condensation can still form on the cold wall as warm air passes through the plasterboard.
While the width of the battens is your choice, they should be wide enough to overlap the edges of the larger boards by at least ½ inch on both sides.
Rough sawn, unseasoned boards or boards surfaced on one side and two edges (S1S2E) are commonly used for board-and-batten siding. Sizes are from 1 x 2 in. to 1 x 12 in. Boards up to 6 in. wide should be fixed with one nail per bearing driven through the center of the board.
Timber battens should be fitted vertically to the building to support the cladding, the battens should be pressure treated softwood, typically of minimum size 25 x 38mm (1 x 1½ inch) - the thickness of the battens should be at least 1½ times the thickness of the timber cladding to ensure they are thick enough to take
Purlins and battens are not synonymous. Purlins are placed on edge and battens are placed on the flat.
You do not have to use a batten roofing system under most building codes. In some cases, it is necessary, but in most cases using batten on your roof is a choice to gain the benefits of using this system. There are primarily two options for roofing, a direct to deck system or a roof batten system.
For all roof areas and rafter pitches, every tile should be mechanically fixed with at least a nail, a clip, or a combination of these options that provide adequate combined resistance to the wind uplift loads on the tiles. For roof pitches of 45° and above, each tile should be fixed with at least one nail.
Measure between the top of the top batten and the top of the lower batten and this divide this measurement by the manufacture's 'gauge' - this will give the number of slates/tiles rows need to cover the roof. This number is very unlikely to be a whole number, so round the number up to the next whole number.

If they are tile battens then from an old roof then that makes it more likely that they aren't treated . The batterns are one off the first things to be replaced on any roof work and are far less likely to be retained and retro sprayed.
JB Red is the branding given to our BS 5534 graded roofing battens, which are coloured red to help identify the batten as graded on site. It is part of the trademark that sets the JB battens apart. This gives a straight distortion free batten that is light to handle and meets the required moisture content in BS 5534.
Blue in colour indicating that each individual batten has been assessed, graded and complies with the strength requirements of BS 5534. Roofing battens, also known “Slaters' lat” act as a fixing point for tiles on a pitched roof. Pressure treated for a longer life, eliminating the need for annual re-treatment.
Other treated timber including battens are pressure preservative treated with Tanalith E and roof battens are completed to BS5534.
