When using plain tiles, battens should be fixed to rafters no more than 600mm apart, and should span across at least 3 rafters. The minimum batten spacing for rosemary roof tiles is 88mm, with the maximum spacing being 115mm for a 90° roof. For a 45° roof, the batten spacing would therefore be 137mm.

How to Calculate Batten Spacing for Other Kinds of Roof Roof Batten Spacing for SlatesĬalculating the batten spacing for roof slates is thankfully quite easy.

105m (roof side 1) + 105m (roof side 2) = 210mįor my roof structure, I would need 210 metres of batten material in total (not including extra for damages/mistakes).

7m (eaves length) x 15 (tile rows) = 105m (as both eaves are equal, this is the same calculation for both sides).

Each side has an eaves length of 7m (7000mm) with 15 rows of tiles.

I am measuring a standard two-sided roof structure.

If you have measured in feet, convert the measurement to metres.

We suggest adding on a few extra lengths of batten to accommodate any potential damage or mistakes.

To calculate the total length of batten material required for the entire roof structure, add together the lengths of the battens needed for each section.

We recommend splitting up your notes to make this step easier. This will give you the total length of battens needed for each side of the roof.

Multiply the number of rows in each section of the roof by the length of the eaves for that specific section.

Note these measurements down separately but do not add them together.

Measure the length of the eaves for each section of the roof.

You can do so by following this easy method: To ensure you have enough battens to cover the square metreage of your roof, you’ll also need to calculate the total length of batten material required. Therefore, the batten spacing for this roof should be 325mm.

5200mm (distance from bottom to top) ÷ 16mm (number of tile rows) = 325mm.

5200mm (distance from bottom to top) ÷ 330mm (maximum tile gauge) = 7mm rounded up to 16mm.

After measuring, the distance from top of the bottom batten to top of top batten is 5200mm.

400mm (length of tile) - 75mm (overhang) – 25mm (nib) = 300mm (distance to next batten).This will give you the batten spacing for your roof, or its batten gauge. Divide the distance between the top and bottom battens by the number of courses.This will tell you how many courses are needed to tile your roof. Measure from the top of the lowest batten to the top of the highest batten, then divide this number by the maximum gauge recommended by the manufacturer, and round this up to the nearest whole number.Once you’re happy that this is correct, fix the batten into place. Make sure that the batten is placed so that the ridge tiles will overlap the top course of roof tiles by around 75mm. Position a batten just below the ridge (the top of the roof) and lay another sample tile onto it.This will give you the correct distance between the first and second batten, which you can now fix in place. Subtract the length of the nib and the length of the overhang from the total length of the tile.Then, measure the tile nib (from the top of the tile down to the bottom of the nib), and note this measurement down too. Measure the length of the tile and note this down.The bottom edge of the tile should stop just short of the gutter centre. Lay a sample tile (not fixed) so that the bottom edge overhangs the fascia and guttering by the amount suggested in the manufacturer’s guidelines. Start by establishing the position for the first roof batten at the eaves (the lowest point on the roof).Below, we’re going to talk you through a simple and practical method for calculating the correct roof batten spacing for your tiled roof. The distance between roof battens is often referred to as the batten gauge. There’s no question that working out the right roof batten spacing is a critically important step, whether you’re building a pitched roof on a new build, or finishing off a refurbishment project by tiling the roof. How to Calculate Batten Spacing for Roof Tiles Battened roofs are also easier to maintain and are capable of withstanding harsh winds without faltering. As well as providing a robust anchor point for the nailing of slates and tiles, battens can also help to increase ventilation and weather resistance, reduce ice damming, and even reduce heat loss and gain.

Roof battens are lengths of wood that are fixed along the trusses of a roofing structure to form a base on which roof tiles can be hung.
