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.
Plain tiles are laid on the battens in a brick bond pattern i e.
Having set out and nailed all the battens the setting out of tiles on each batten should be considered.

Roofing with plain tiles positioning the battens.
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 first course of tiles should be set out to equalise all the gaps between the tiles start and finish at corner or abutments and hopefully line up with the sides of window openings.
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.
After you have determined the distance between the first two battens measure the distance and set battens using that.
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.
