PITCHED ROOFS: are usually covered with tiles or slates which either fix, or clip over, battens. These battens sit on a roofing membrane and are nailed to the rafters below. The battens are fixed at regular intervals according to the gauge (distance between battens) specified by the tile manufacturer. This in turn will vary according to the angle, or pitch, of the roof.

Each tile must overlap the tile below it and this is critical  in working out how to tile even the porch roof we mentioned above.  If you are unsure which tiles you have Bmc Builders are always here to help.

The two main players in the roof tile market are Marley and Redland. Marley started making roof tiles in 1924 and Redland in 1919, both are still going strong with a huge range of tiles and slates. Different types of tile vary hugely in size with the small clay, or concrete “Plain tiles” at only 265 x 165mm compared to the largest of roofing slates at a giant 600 x 300mm. Both Marley and Redland manufacture similar tiles but they do not quite interlock with each other. It becomes very important then to identify your tiles correctly to ensure its weather resistant and a good finish to your property.

FLAT ROOF COVERINGS:

EPDM:

EPDM stands for Ethylene-Propylene-Dyne-Monomer. Basically it’s a synthetic rubber roofing material that is manufactured specifically for flat roofs.

EPDM has been in the UK for a pretty long time, but it is only until the last few years that is now becoming a very popular choice for waterproofing flat roofs in the residential market.

EPDM has many benefits over other systems. These being; Very flexible-elongates to 300%, resistant to UV, long life span, can be used to overlay old roofs (subject to a structurally sound deck) does not crack or perish and very environmentally friendly. These key points are everything that property owners in the UK are looking for.

EPDM was developed in the states back in the 80’s A true test of time, with a proven track record.

With the climate we have in the UK, from ice cold winters to sometimes hot weather, a good roofing product needs to be able to perform to these two extremes. Again  EPDM has already been put to the test, as commercially it has been installed in Alaska at -45 up to 130 degrees plus in the Middle East. So as you see, the UK climate is no problem for EPDM.

GRP:

GRP (Glass Reinforced Plastic) also known as fibreglass. This consists of a matting of glass fibre strands used in conjunction with a flexible resin compound which cures to a tough and durable finish.

GRP has been in use for many years and has been used for marine craft such as boats and yachts. It has also been used for car bodies and is found in aircraft manufacture. It is also recognised by construction authorities and home insurers as a premium flat roofing solution. We believe that it is
 the ultimate solution for flat roofing; it will require no maintenance and will look good for years. A GRP roofing sytem will give you peace of mind for many years to come.
