| How
long does a GRP roof or gutter last?
A
GRP Roof or gutter lining will remain virtually maintenance free for a period
in excess of twenty five years. GRP roofs that have been protected from UV degradation
by chippings on the gel surface should remain serviceable for considerably longer.
After twenty five years, a new gel surface can be applied to roofs and gutter
linings extending life expectancy even further (subject to specific site conditions).
Unprotected GRP rooflights
are still in use forty years after installation. |
| What
does it cost?
Compared
to traditional roofing materials (felt and bitumen based products) fibreglass
materials are more expensive although this additional cost is offset by vastly
increased life expectancy. In many cases GRP is a cheaper alternative to traditional
materials due to faster installation and the reduced need to strip out existing
materials, roof sheets/tiles or glazing bars etc. The price per roof or gutter
lining is often dictated by site conditions, please contact
us
for further information and budget pricing.
|
| Is
the work guaranteed?
All
of our work is guaranteed. Please contact
us
for specific information and insurances etc. |
|
Can I
walk on it?
A
GRP roof or gutter lining is perfectly safe to walk on, and is far less likely
to be damaged compared to traditional roofing materials. Pedestrian access can
be easily incorporated in roofs or gutter linings and specific specifications
can be used for roof gardens or balcony/patio areas etc. |
| Can
GRP be used on pitched roofs?
Fibreglass
has for many years been used successfully on pitched roofs as well as flat areas.
Rooflights and Velux installations are easily incorporated into the new GRP roof.

| Does
my existing roof have to be re-decked?
As
the GRP roof systems we use lend themselves to over-roofing (providing the existing
deck is in serviceable condition) it is not always necessary to strip the existing
roof covering and decking. An initial site survey should establish whether the
existing deck should be replaced as per building regulations. |
| Can
my GRP roof be used as a roof garden?
Fibreglass
roofs are much stronger than traditional felt roofs , and so make excellent roof
gardens, balconies and patio areas. |
|
What colours/surface
finishes are available?
Our
standard specification GRP roofs are finished with white FLEX-TRIM edges and an
application of clean 6mm lime stone chippings embedded into the white gel-coat
surface. Most aggregates could be used instead of lime stone, or in certain circumstances,
the surface can be finished with the gel-coat surface left bare, or a non-slip
surface applied. Most colours can be supplied, please contact
us
for specific information. |
|
Can a
GRP roof incorporate insulation?
Insulation
can easily be incorporated beneath the GRP roof structure (in accordance with
warm roof/cold roof situations). |
|
Does
a GRP roof require venting?
We
create a breathing roof system which allows moisture vapour to vent at the edges
without compromising the roof's overall integrity. Larger areas may require the
inclusion of roof vents that are easily incorporated into the roof structure. |
| Can
a GRP roof incorporate flashings/soakers or a Velux?
GRP
roofs are ideal for the incorporation of flashing details and specific soakers
for Velux units or rooflights etc.
Independent
GRP soakers or flashing units can also be manufactured on site for use on a variety
of roof surfaces (tile, fibre cement sheet, slate etc.) although we still advocate
the use of a lead flashing to the perimeter of our GRP roofs to aid in the transmission
of moisture vapour. Top

Can a
GRP roof incorporate a gutter detail?
A
gutter detail is easily incorporated into the roof structure, as are most shapes
and roof pitches. |
|
Do we
supply GRP Materials/FLEX-BASE/FLEX-TRIM?
Please
contact GRP
Refurbishment Systems
for information on material supplies. |
|
Can we
refurbish GRP rooflights?
As
an alternative to replacement, old GRP rooflights can be repaired and have a new
gel-coat surface applied in-situ. |
|
Are COSHH
assessments required?
COSHH
assessments are always completed before any work commences, as required by health
and safety regulations. COSHH assessments and material data sheets are always
available on site. |
|
What
types of gutter are suitable for a GRP lining?
Most
commercial and domestic gutters are suitable for a GRP lining, although it may
not be practical for some rainwater goods. Please contact
us
for specific enquiries. |
|
Is GRP
suitable for a fragile/rusting gutter?
The
GRP gutter linings we manufacture are reinforced at the base with a special synthetic
core material sandwiched between further layers of glassfibre, producing a structure
of great strength (but lightweight). As an independent lining (as long as the
gutter supports are still serviceable) GRP can safely be installed over (or within)
a fragile structure. |
|
Is a
GRP gutter lining suitable for a house?
Our
GRP gutter linings are suitable for domestic and industrial applications. |
| Our
existing gutter is stepped, is GRP suitable?
A
stepped gutter (usually the result of a lead gutter installation) is perfectly
suited for a GRP gutter lining. The seamless construction of a GRP gutter lining
can accommodate most shapes, sizes and protrusions through the gutter itself.

|
Does
the existing gutter have to be stripped out?
Most
gutters can be lined in-situ without the need of stripping out roof sheets, glazing
bars and flashings etc. In some cases e.g. when a timber gutter has rotted, the
gutter structure may have to be rebuilt, and then lined with GRP. |
| Can
a GRP gutter lining incorporate insulation?
Insulation
can easily be incorporated beneath the GRP gutter structure (in accordance with
warm roof/cold roof situations) as long as the volume of the gutter has been increased
to compensate. |
|
Is a
GRP gutter lining suitable for asbestos cement gutters?
GRP
gutter linings are especially suitable for installation to asbestos cement gutters,
as the installation process virtually eliminates disturbing the original gutter
structure or adjacent asbestos cement roof sheets and closure panels. |
| Can
a GRP gutter lining increase the capacity of my gutter?
We
always try to maximize the volume of a GRP gutter lining by utilizing the available
space beneath the roof covering. As the lining sheet is preformed, we are able
to slide this sheet (FLEX-BASE) behind any closure panels (splash plates) or up
to the first batten on a tiled roof, thus increasing the gutter volume considerably. |
| Can
additional outlets or weir ends be created?
We
create an independent gutter lining (a gutter within a gutter) and so the process
of creating weir ends or additional outlets is very straightforward. |
| Can
any shape gutter be lined with GRP?
A
GRP gutter lining can accommodate most shapes, sizes and protrusions through the
gutter itself. |
|
Will
a GRP gutter lining cope with expansion and contraction?
Yes.
We create an independent gutter lining (a gutter within a gutter) and always take
thermal and structural movement into account during installation.
