in the row above. If they are pushed up hard to the screws
shattered slates can result due to thermal expansion.
The hook length required is related to the batten spacing.
Note that the length of a clip is measured from the bottom of
the clip to the bottom of the screw hole.

15. Eaves
– slating is started at the eaves, from a verge if
present, with a line of the clips screwed to the first batten at
the slate width interval, and a line of eaves slates hung on
these. A row of clips are then screwed to the first batten
between these eaves slates and the first row of standard
slates hung.
½ size eaves slates (500 series, 250x285mm) and 1½ size
eaves slates (600 series, 450x335mm) are available.
The eaves will overhang the first batten by the clip length
minus 25mm. Where this overhang is too small, longer clips
may be used if available, although then the batten spacing on
the first course may need to be reduced.
16. Verge
– If the roof runs from one verge to another it is an
advantage to design the roof to fit an exact number of slates,
to the nearest half slate, using the slating interval given. The
slates should overhang the verge wall by around 50-75mm,
taking account of whether a bargeboard will be used. The
verge can be finished using an undercloak of conventional
slates in the normal manner or a dry fix verge can be installed.
Alternatively, depending on local regulations, the edges of the
slates can be left as they are with just some cement or a
bargeboard to fill the gap above the wall top.
Unless secured with a dry fix verge, the edges of the verge
slates must be secured to the battens with verge clips
(supplied). These are screwed to the lower edge of the
battens so that each secures three layers of slates, and the
end should be bent in slightly so that it grips the slates. These
clips may be installed before slating commences, using a line
to get a neat edge.
The first full height verge slate from the eaves will be a 250 x
500 slate (500 series) or a 450 x 600 holed slate (600 series).
The 250 wide slate will require a clip modified to go around
the thickness of both the eaves and verge slates – this is
easily achieved with a pair of pliers. The 450 wide slate-and-
a-half has a hole for the clip in the row above. This must be
positioned correctly, and with the clip screwed through the
lower hole where possible.
If running out to a second verge, which does not fit to the
