gable ends

[sudbrooke]

not sure if this should be in Roofing section, or here.....

Building a gable end, should the slope of the outer skin, and inner blockwork, be on the same level as the rafters, or is the outer skin lower than the rafter. to allow for bedding the final tiles onto the bricks? If so, how much?

And where do the battons supporting the tiles stop?

Won't the weight of the tiles make the battons sag down over the last 300 mm where they cannot be nailed to the rafters?

The strip of sheet material (not sure what it is called) that allows the tiles to go an inch or so beyond the outer skin - how is this fixed to the wall?

Thanks!

To answer your questions...
The gable end brickwork is finished (as long as there's no barge board) to the same pitch as the rafters, and to the same height.

The battens should finish 15mm or so back from the face of the brickwork.

The batten ends won't sag as they should be sat on the brickwork. Plus the mortar used to bed the tiles on will help also.

The sheet material you refer too Asbestolux) is only normally used with a barge board. It goes under the end of the battens, and is nailed into the barge board. It sounds like you intend to just sit the slates/tiles onto the brickwork? In which case they should be bedded on to the wall (roof felt 50mm back from wall edge) with mortar and flushed up neatly.

Hope that's of some use.

Cloak is used on both cut gables and barge gables.

The actual cloak can be formed with cement board or bedded plain tiles.

If you are building a cut brick gable i would suggest keeping the masonry down 10 - 15mm from the rafter top to allow for cloak bedding. If you are using a tiled cloak set the masonry down 20-25mm.

In some instances cement board cloak is fixed on top of the tile battens, the barge is then brought up to cover the batten ends.
