With low
pitch roofing products continuing to be in high demand, Marley has launched a
new concrete interlocking tile, which can be used down to a minimum pitch of
just 12.5 degrees.
The new
Mendip 12.5 has the same double pan design as the original concrete tile, but
includes some innovative features to ensure it can be used at a lower pitch.
Designed
with single storey extension projects in mind, the Mendip 12.5 has four
weatherproofing channels at the face of the tile to prevent water ingress from
wind driven rain. To make it even more watertight, the tile has no nail
hole and is instead installed with its own Mendip clip.
As well as
the original Mendip tile, which can be used down to pitches of 15 degrees, the
range now features the Mendip 12.5 in two colours - Smooth Grey and Smooth
Brown - giving contractors more choice on low pitch projects.
Daniel
Redfern, from Marley, comments: “The increase in single storey rear extensions,
following the relaxation in planning laws, means we are seeing increasing
demand for low pitch roofing products. We already offer an extensive low
pitch range, with a selection of clay and concrete tiles that can be used from
17.5 down to 12.5 degrees. However, the lowest pitch concrete tile in the
range only went down to 15 degrees, so we wanted to offer contractors an even
lower option for extension projects.
“Single
storey extension projects often require a lower pitch roof due to the position
of first floor windows. Standard tiles aren’t always suitable because
weather tightness decreases as the roof pitch gets lower and it takes longer
for water to drain from the roof. However, Mendip 12.5 has been designed
with discreet features to channel away wind driven rain and keep it watertight,
so it is guaranteed to perform at much lower pitches.”
The Mendip
12.5 is installed with a head clip and it is also compatible with the speedy
SoloFix one-piece clip and nail, which can be used as the second clip in
accordance with BS 5534.
When
installing to a low pitch of 12.5 degrees, it has a maximum 100mm head lap and
can be used at six metre rafter lengths only.
The new
tile also has strong sustainability credentials, including an A+ rating in the
BRE Green Guide to Specification and an ‘Excellent’ BES 6001 Responsible
Sourcing Certification.
