Q) Why is the Cembrit system more Hurricane resistant than other
forms of roofing?
A) The primary reason is the method of fastening. Most roofing
systems rely solely on nails driven into the roof deck. Cembrit on
the other hand has a unique system of four 4" x ¼"
Lag screws per panel. These are screwed into 2" x 2"
horizontal battens, which in turn are screwed through the roof deck
directly into the rafters or trusses. This means that the panels
are structurally tied into the framing of the house and not just
to the decking.

Q) Ok, so what about Termites?
A) Termites eat materials, such as wood, cardboard and other
organic materials. Cembrit panels are manufactured from a
fibre-reinforced cement, which does not attract Termites.

|
Q) How about moss and lichen?
A) Due to its smooth surface, Cembrit does not support the
growth of moss and lichen, making it extremely suitable for
collecting rainwater.

Q) Will it insulate my roof against the heat?
A) Unlike Asphalt, Cedar, Ribbed Steel and other
"flat" roofing materials, Cembrit is corrugated which
allows air to circulate under the panel. As the roof heats up
in the day, the hot air rises and pumps out through the unique
ridge venting system. The eaves are closed with an impregnated
foam strip profiled to the tile. This allows the air to flow in;
but keeps the birds and the bugs out.
|
|
Q) Is it difficult to install?
A) No, normally any roofing company or builder can install
the system. Remember, Cembrit is in panel form, so it is similar
to installing a small sheet of plywood. In fact you even cut
it with a circular saw and carbide tipped wood blade. You do not
use a cement blade.

Q) Will the panels be affected by salt from the sea?
A) Cembrit panels are manufactured from Cement; therefore
they resist the affects of salt air or acid rain. However, the
panels should be installed with corrosion resistant lag screws.
We can supply these if you cannot obtain them locally.
As an added benefit, they will not rot, rust or corrode and
are class “A” fire rated - they will not burn.

|
Q) What about the environment and Asbestos?
A) Nothing in the Cembrit System contains Asbestos and
the whole system is environmentally friendly. Unlike asphalt
shingles, Cembrit does not need to be stripped off every few
years and taken to the landfill site, where they leach into the
ground water. Cembrit can actually be installed over a layer of
shingles, which eliminates the cost of their removal.

Q) How do I know what I will need for my roof?
A) If it is a new building, you should send us your
Architectural drawings, if an existing roof we will need a good
quality sketch drawing with all the dimensions and roof pitch.
The materials required for your roof will be calculated from
these drawings. We will then submit the full quotation to you;
with all the materials you will need itemized, what it’s going
to cost and how much the shipping will be. If some of the
installation materials are not available locally, we can supply
them from our Canadian offices.

Q) What’s the difference between the B6 & B7 panels?
A) The B6 is a larger panel covering 11.7 sq ft. and is
normally used for commercial, institutional and affordable
housing. The B7 is a smaller panel covering 5 sq. ft. and
looks more like clay tile when installed. It is therefore
used mainly for residential and hotel roofing where superior
aesthetics are required.

|
|
Q) What’s the B9 Panel used for?
A) The B9 is a non-coated panel, which is only available in
the natural cement grey colour. It is manufactured in exactly
the same way as the B6 and B7 and has all of the same accessories
and benefits. The B9 panel is available in 4ft, 6ft & 8ft
lengths. It is primarily used for Agricultural, Industrial and
Commercial uses.
