How To Batten A Roof For Tiles

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.

How to batten a roof for tiles.

When set in mortar a cut batten end should be treated or the batten turned so that the treated end is in the mortar. The slate or tile manufacturer or supplier will specify the size of battens to be used typically this would be 40 x 20mm 1 5 x inch but where the horizontal gaps between rafters is large or the slates tiles are heavy then. Set the last batten at the ridge so that the ridge tiles will overlap the top course of tiles by at least 75mm. The spacing of the roof battening highly depends on the type of exterior roofing material that is going to be used.

Next place your two tiles one on top of the other loose onto the battens without anything being fixed. This is not required for dry fix systems. How to space a tiled roof firstly get two of your roof tiles and either two full battens or two offcuts of batten and place them onto the roof one above the other. Just short of the centre of the gutter.

Make sure the tile lugs are seated snuggly onto the top edges of the battens. With dry fix systems the batten cut end is deemed to be within the roof and does not require treating. The batten should be positioned so that a ridge tile will overlap the roof tile by roughly 3 inches. For example horizontal battens run.

Joints should be directly over rafters with the batten square cut tightly butted and skewed nails. If a batten end is to be set in mortar be sure an appropriate treatment has been applied. For example metal roofing will be attached to special metal roof battens. Battens should be nailed to the centre of the rafter and any joints should be directly over a rafter with the batten square cut tightly butted and skewed nailed.

Use two tiles to determine the spacing required for the battens. Hold a final short strip of batten across the top of the roof just below the ridge and rest a tile on it. A minimum of a 3 inch overlap is required for the tiles. How you install battens can affect the drainage efficiency.

After you have determined the distance between the first two battens measure the distance and set battens using that. Start at the lower edge of the roof nailing the batten into place at the centre of the rafter. The batten seams are covered with batten joint and then the metal sheets are attached at specific intervals.
