How To Set Out A Roof For Tiling

Roofing battens are nailed into the rafters or roof joists or trusses and provide support for the roof tiles or slates.

How to set out a roof for tiling.

After you have determined the distance between the first two battens measure the distance and set battens using that. Use two tiles to determine the spacing required for the battens. Roofing with plain tiles positioning the battens. Set the last batten at the ridge so that the ridge tiles will overlap the top course of tiles by at least 75mm.

Start by establishing the position for the lowest batten for the slates tiles on the roof allow for the overhang of the stales tiles in front of the fascia. The updated bs 5334 code of practice for slating and tiling specifies a number of batten sizes based upon the span of the rafters and the product being used. Use a hammer and nails to attach a second short strip of batten further up the roof the distance between it and the first batten being the distance calculated in step 3. Make sure the tile lugs are seated snuggly onto the top edges of the battens.

For example 25 x 50mm battens are required for single lap modern roof tiles laid on rafters with a 600mm span. With the joints between them. Step 5 hold a final short strip of batten across the top of the roof just below the ridge and rest a tile on it. Setting out up the roof gauge set the first batten at eaves to allow the tails of the eaves course tiles to overhang the fascia by 40 to 45mm ie.

The supplier of the tiles should recommend the spacing up the roof between the battens known. A minimum of a 3 inch overlap is required for the tiles. Just short of the centre of the gutter. Having set out and nailed all the battens the setting out of tiles on each batten should be considered.

Each plain tile is 165mm wide and can have up to 3mm gap between them. Then determine the position of the highest batten at the top typically the top of the uppermost row of slates tiles should be at least 75mm 3 inches under the edge of the ridge tile. Next place your two tiles one on top of the other loose onto the battens without anything being fixed.
