nail fixing holes on the batten line, two rivet holes
to hold the tail and an additional hole to
accommodate the rivet for the subsequent single
verge slate.
When trimming to verges, valleys and hips, avoid
using pieces less than 150mm wide. If possible,
use a slate and a half with the cut edges
protected to prevent cement run off due to
exposure to weather.
In practice
A recently completed five bedroom bespokedesigned
house (built on the site of an original
three bedroom bungalow) showcases the correct
method for installing verge slates. The roof was
being replaced as part of the larger project. On
the original bungalow, concrete roof tiles were
installed and the weight of the tiles had made its
roof start to dip in the middle. The typical weight
per m² of interlocking concrete tiles equals 45-
50Kg. In contrast, a m² of fibre cement slates
weighs just 20Kg making them a lighter, versatile
alternative and the perfect choice for this project.
The slates were chosen by Mid Kent Roofing and
professionally installed according to the relevant
British Standards. Particularly worthy of attention
is the verge detail, as seen in the photograph
(left) showing double slates cut to a slate and a
half. With two rivets and three nails, there is very
little chance that environmental conditions will
affect the verge slates, which, as discussed, can
be vulnerable to lifting if fitted incorrectly.
