The Klober Kolumn
In the latest of its FAQ series, the technical support
team at Klober takes RCI readers through some
of the more common queries received by the
When do I need to use hip trays when installing a roll
It all depends what roof finish you are using. If you are using slate
or plain tiles, there is no need to install hip trays. If you are using a
concrete profile, such as Double Roman tiles, then it’s important to
install hip trays as this provides vital support – making sure that the
finish is as aesthetically pleasing as possible.
Can your continuous dry verge be retro-fitted? If so
Yes – continuous dry verge can be retro- fitted, although it does
however become slightly more complicated than if it was a newbuild
or complete renovation. We would advise stripping back the tiles
along the gable end and making sure the battens are cut back level
along the verge. You will need to fix the verge under the battens as
this makes sure the product is secured. As the tile/slates are laid,
ensure that the verge tiles are extended fully into the verge strip
where they will be firmly held.
Would you introduce extra ventilation when using a
membrane like your Permo air?
We would advise against installing extra ventilation when
installing Permo air. The reason for this is that when you install extra
ventilation, you are introducing cold air into the ventilation space.
This can cause cold spots, which in turn, can cause condensation
