Photos of a box gutter being lined with EPDM single ply rubber
The builder has built a new side extension and we left the decking
open ready to lay a new single ply EPDM rubber flat roof.
RubberBond EPDM single ply rubber roofing
is in fact gas permeable and the main adhesive used to lay it is
water-based. The moisture in the decking and from the adhesive will
evaporate through the EPDM rubber. However its is
good building practice to lay a new roof covering
only on a dry roof, and in this case the
roof was allowed to dry before laying.
This photo shows that the builder has lined the sides of the
parapet walls, ready to receive the EPDM rubber single ply.
This is an option as the open brickwork could either have been
rendered or left open. However by leaving it open, the finished look
of the job would have been compromised, so for not much more cost,
rendering the brickwork makes the EPDM rubber roof
look superb.
The EPDM single ply Rubber is being
set out here for laying. You can see that joints will be minimal.
In
this photo the EPDM single ply rubber
has been dressed up the parapet walls and over the decking. It has
been glued into position and the internal corner is being dressed,
ready for finishing. By dressing the corner in this way there is no
possible way that the corner can leak, even before it has been
finished, as there is no open cut at decking level.
The
EPDM will be dressed over the top of the
surrounding parapet walls, ready for coping stones to be laid. There
is no need for any lead or any expansion joints.
The
EPDM rubber is very flexible and lends itself to
being dressed up and around most corners. The large sheets minimise
joints and this cuts down on labour costs.
The
decking and all the edges of the EPDM Rubber have
now been glued down. The final patching is about to take place, and
as you can see, the flat roof is really taking
shape.
This
is the finished EPDM single ply box gutter, ready
for the builder to tile the pitched roof around the
skylights. Coping stones will also be set onto the parapet wall.
